It´s easier on wheels - Sliding friction vs. rolling friction - February 2020
The new roller belt BRECOroll
Friction as a tribological loss value is unwanted in most technical processes. It leads to a temperature increase and wear and wastes drive power. To minimize this friction when using polyurethane timing belts in material transport systems, BRECO has developed a new product.
BRECOroll is a new development featuring rollers integrated in the teeth of the belt. BRECO has designed this product for applications in material conveying systems. Timing belts used to transport materials are usually very long. The load run of the belt is almost always supported by a support rail, which guides the belt on its sides and absorbs the weight of the workpieces on the belt and of the belt itself. This generates friction between the belt and the support rail. Frequently, a significant percentage of the drive power is used to overcome this self-inhibiting behaviour of the system. During this process, the drive is subject to major forces, generates heat and runs at a low degree of efficiency. The increase in the belt temperature lowers its stability – in particular, that of the welded point of the V connection – and reduces the service life of the belt. Rollers in the belt teeth replace the sliding friction with rolling friction, which is significantly lower. A significant reduction of the drive power is possible and the system’s self-heating behaviour decreases considerably.
The space required for the axis and roller can only be provided by a large belt tooth with a pitch of 20 mm. The T profile is better suited to this application than the AT profile, because the tooth crown of the AT belt makes contact in the pulley while running around it.
The BRECOroll is only available in the T20 division and only in 100 mm width. Please contact our sales partners for more information.
New item in our product range - transport with vacuum - October 2019
products such as films, paper, glass panes or thin metal sheets to a timing belt by means of a vacuum to transport them. The timing belts and associated components used for this purpose are almost always special developments designed and implemented by our application engineers together with the final customer’s design engineers. Every customer gets their own system, consisting of a timing belt, pulleys and vacuum or sliding rails.
Our new product, BRECOvacuum, provides an alternative. BRECO has developed a system of timing belts and pulleys which combines the drive tracks, i.e. the tooth systems, the vacuum channels and the required sealing bars. A coordinated component system is available. The geometric configurations of the individual pulley components are precisely adapted to the vacuum area on the timing belt. This prevents, for instance, wear caused by faulty tolerance adaptation of the two elements to each other, thereby increasing the system’s service life. Recommendations for the geometric design and ideal tolerance ranges of the “vacuum rail” are available.
As almost the complete BRECOvacuum is created in an extrusion process, its cost is lower than that of a belt produced in a step-by-step process. The system is currently being introduced in the AT10 version with two widths, 50 mm and 75 mm.

THE POWERHOUSE - April 2018
... that you hardly see.
Ten years ago, BRECO launched two optimised products in 15 mm pitch,
BRECOFLEX and BRECO-ATS15. In comparison to the AT20, the ATS15 timing belts have a lower polygon effect due to the pitch, and a higher number of meshing teeth with an almost 30% increased tooth shear strength. So the market has these two products, the only thing missing being absolute stiffness.
Now the BRECOFLEXmove timing belt
AT15 and BRECOmove timing belt
AT15 offer this missing property (BRECOmove timing belt
AT15 is available from October 2018). In addition to the familiar high tooth shear strength of the ATS15, the tension members used in the AT15move permit an approx. 40% higher belt stiffness with comparatively low minimum number of teeth, and smaller diameter with and without contraflexure. The AT15move timing belts are much stiffer than the ATS15, AT20 and ATL20 timing belts of the same width.

50th anniversary at BRECO - November 2017
The start of a success story
On Thursday 16 November 2017, BRECO will celebrate the 50th anniversary of its founding. Rudolf Breher founded BRECO as a tool making and plastics processing company with a staff of five employees and a production area of about 100 square metres, laying the foundation stone for the success, which continues today. The tool making can be regarded as the nucleus of the company. The first products were injection moulding dies for plastic parts and steel flanges, extrusion coated with polypropylene for the chemical industry.
Rudolf Breher was an innovator with an entrepreneurial instinct, who tried out new ideas, found new solutions and knew how to successfully implement them in innovative manufacturing processes and products. In 1968, the manufacturing process for producing open length timing belts from polyurethane (thermoplastic) was developed and filed for patent. This was followed seven years later by the patent for the extrusion process for manufacturing endless BRECOFLEX® timing belts. Success was underway
In 1968, BRECO joined Mulco, and in close cooperation with the individual member companies, BRECO® and BRECOFLEX® timing belts were successfully established as high-quality and versatile drive elements.
The company continued to grow due to shrewd investment in personnel and machines. Now BRECO employs a staff of 270 on a production area of about 12,000 square metres.
Specialising in the development of individual drive solutions, BRECO established a leading position in the market for polyurethane timing belts from the beginning. We will continue to defend and strengthen our leading position.
[was scarcely seen] - April 2017
New ads since March 2017
Since March 2017, BRECO has been branding new ads in the media with the title"... .was scarcely seen".
Hidden behind this mysterious headline is the task of our toothed belts:
In the background, as well as invisible to the eye their services reliably to settle.
Whether it is the BRECOprotect, which is particularly suitable for the high requirements in contact with foodstuffs,
the BRECOmove, which can transmit higher forces without problems, the BRECOgreen, which is produced to 37% of renewable raw materials, or the BRECObasic, which is a cost-effective alternative for simple applications.
This is movement.
BRECOmove - the belt that doesn´t give up - October 2016
BRECOmove for linear technology applications
After the successful market launch of the endless timing belt BRECOFLEXmove AT10, BRECO supplement the "move" product range with an open length version.
The BRECOmove timing belt AT10 demonstrates its strengths, in addition to high power transmission, particular in linear technology applications. The very high stiffness of the belt is the basis for excellent dynamic behaviour with short settling times and high positioning accuracy. This makes BRECOmove an excellent alternative to comparable standard timing belts as the AT10, ATL10 and the AT20. The available belt widths are 25, 32, 50, 75 and 100 mm.
Extension of the product range - BRECOprotect® - January 2015
More types, more possibilities
The product line BRECOprotect® currently includes the timing belt types AT10, AT15 and T10 in open length (BRECOprotect® M) and joined versions (BRECOprotect® V). The belt widths 16 (only T10), 25, 32, 50, 75 and 100 mm are available. This range will be extended by adding the timing belt types AT5, AT20, T20 and the flat belt F3.
BRECO PinLock - December 2014
Precise. Secure. Easy to assemble.
BRECO® PinLock is the name of a timing belt lock that is quick and easy to install. The high-precision water jet cut finger-type contour allows simple joining of the belt ends on site and guarantees excellent flexibility and smooth running. The optimised finger contour ensures uniform distribution of the load throughout each cross section and thus a high load bearing capacity of the connection. Stainless steel slotted set screws are used as pins and can be screwed in using the supplied bit and a cordless screwdriver without any special devices.
Sometimes you need a partner ... - October 2014
...with more power. The new BRECOFLEXmove AT10.
With BRECOFLEXmove AT10, BRECO has created a new high-performance belt that offers a 30% higher transmittable peripheral force than the standard BRECOFLEX-AT belt. With the same boundary conditions it offers 30% higher reliability and can be reduced in width by 30% compared to the standard version, allowing a more compact design and offering additional cost benefits.
Extension of our product range - BRECObasic® - October 2014
"Simple, good, reliable." This will also apply to the BRECObasic® open length TK10K13 BAS as of October. With this addition to the range, BRECO is offering a conventional transport belt with V-groove guidance in the basic price segment. The TK10K13 BAS is available in the widths 32, 50 and 100 mm and as 50 or 100 m rolls. The coating materials offered in the BRECObasic® catalogue - T version, T-groove, PU yellow basic, Supergrip basic and PAZ coating - are also available for this type.
AT timing belts - Even better than before - January 2013
AT profiles with higher load bearing
Thanks to the consistent use of high-quality materials, excellent cooperation with our raw material suppliers and the continuous improvement of our manufacturing processes, numerous tests have proven that our BRECO® and
BRECOFLEX® timing belts with AT profiles are even better than specified in the catalogue.
Due to the successful improvements in product properties achieved over the past few years, BRECO can now permit a 20% higher specific tooth load bearing capacity for AT profiles used in high-speed drives compared to the previous catalogue values; this applies with immediate effect.
The respective values have been updated in the calculation program "belt pilot" the updated PDF versions of the printed catalogue can be downloaded from our Website.
BRECOgreen - Sustainable. Eco-friendly. Green. - October 2012
The green product version
Climate and environmental protection and a conscientious use of natural resources are global issues that affect all areas of our lives. Now, BRECO emphasizes its innovative strength not only in the area of manufacture of high quality products, but also in the area of environmentally responsible management of the raw materials used. Decreasing availability of natural resources, increasing CO2emissions and an increased strain on energy supply have prompted us to optimise our use of materials.

BRECObasic® - Simple. Good. Reliable. - September 2012
The grey product version
The range of products offered by BRECO under the banner of the "BRECObasic®" brand is an inexpensive alternative for simple applications that require less than the full potential strength of standard-type BRECO® timing belts. The range is designed for applications that do not come with special demands relating e.g. to restricted tolerances, particular durability/ resilience requirements or further processing options for the timing belts.
BRECO®-fix Clamping elements - July 2012
The new generation
The BRECO®-fix clamping elements are used in linear systems. Clamp connectors and clamp plates optimally adapted to our timing belts are available for diverse areas of application. Both elements are used to fasten the belt ends on the machine frame or on the moving unit.
While the clamp connectors only enable simple fastening of the belt ends, the clamp plate can also be used for setting the pretensioning force via a clamping unit. The different variants A, B, and C specially optimised to the load are available to the user within a complete clamp plate system for the individual belt types and belt widths. The different variants and subcategories ensure absolute clamping reliability together with optimum handling and assembly thanks to their design. Providing a complete system comprising base plate, if necessary toothed insert, upper plate, clamping unit and standard part accessories spars the user awkward assembly and coordination of the individual parts. In addition, using the toothed inserts made from high-strength polyamide in the clamp plates of variant B allows production costs to be optimised. This results in a system with a very good price-performance ratio overall.

Beware of Counterfeits! - November 2011
Quality cannot be copied!
BRECO has been informed that, despite patent protection, a Chinese manufacturer has been producing ATN type polyurethane timing belts with counterfeit BRECO logos imprinted on the tooth side and exporting these imitations to Europe.
Luckily, quality cannot be copied, only comprehended.
We are warning our customers not to use these imitations. These are belts of inferior quality, which do not even come close to meeting our quality standards. Though these imitations are difficult to distinguish from the original at first glance, the tension members and polyurethane are of poor quality and the ATN pockets do not have the same dimensions as ours, so that problem-free operation and long service life are not guaranteed. If you did not purchase your ATN timing belts directly from one of our authorized sales partners, please verify your purchase source and contact us immediately should there be any doubts about the authenticity of the product.
It cannot be ruled out that other timing belt types with our BRECO logo have also been counterfeited. For this reason, we expressly warn against purchases of alleged BRECO products from Asian countries.
We will use every means at our disposal to put a stop to this misuse and hope for your continued full confidence in our products.
Breher GmbH & Co. KG
BRECO TSM alpha 1 - November 2010
Pretension is one of the few parameters the user of timing belt transmissions has to set. Pre-tension is intended to guarantee a minimum tensioning force at the slack span side to ensure smooth tooth meshing into the driven pulley. As such, it considerably influences the operating behaviour and the longevity of the entire drive.
The new fully electronic span measuring device BRECO TSM alpha 1 allows the reliable checking of the set pre-tension force of the timing belt transmission.
The Advantages at a glance:
• contactless measurement with one-sided belt touch
• measuring on all belt types including all different types of tension members, e.g. steel, kevlar, glasfiber
• reliable measuring results that are highly reproducible
• connection for external sensor for measuring hard-accessible parts
• an LCD indicating how full the battery is
• optical and acoustical indication necessitating a change of battery
