Timing-Belt Drives

Contrary to V-belt drives, timing belts are synchronous drives. The rotation is transmitted in an angle-synchronous way. This is why the official name of this belt is “synchronous belt”. Power is transmitted when the teeth on the belt (positioned in regular distances to each other) fit in the corresponding openings on the pulley. Most timing belts are made of rubber filled with tensile cords made of glass fibre or steel.

The Stemin Breitbach range of timing belt drives includes: SilentSync (EAGLE-Pd) [8M-14M], FALCON-Pd [8M-14M], TOPDRIVE HTD & MUSTANG SPEED & MUSTANG TORQUE [3M-5M-8M-14M], HPPD-PLUS [3M-5M-14M-20M], STS [S3M-S4.5M-S5M-S8M-S14M] und Zöllig (Inch) [MXL-XL-L-H-XH-XXH].

SILENT SYNC (Eagle-Pd) Timing belt Drive

more information
Unique combination of the SilentSync belts and the sprockets utilizes an Helical Offset Tooth (HOT) design that reduces noise to industry’s lowest level (up to 20 dB(A) is possible). Continuous rolling tooth engagement and flangeless sprockets provide self-tracking, reduced vibrations, greater efficiency and design flexibility. The SilentSync belt (Polyurethane) is also available in... [ read more ]

Inch Timing-belts

more information
This is the first generation, traditional timing belt with trapezoidal tooth profile. This neoprene timing belt is suitable for low power ratings and is wide due to its low tooth shearing capacity. This belt is also available as an open-end design.
