Double-Sided Timing Belts
Double-sided timing belts are intended for drives with a change in the direction of rotation. They are manufactured according to ISO 5296 and can be used in all performance areas.
The standard design allows economical solutions for double-sided synchronous power transmission in the lower and middle power range. The CXP version has been designed for high power and speed. The CXA version has been developed for high torques.
Double-Sided DHTD
DHTDDouble-Sided High Torque Drive
Because of its tooth height and semi-circular tooth geometry, the HTD profile is especially good at avoiding jump-over of the teeth in operation. The HTD profile is extremely suitable for transmitting high torques. The profile is also available in the double-sided DHTD version. double-sided timing belts.
Double-Sided DSTD (Double-Sided STS)
Rubber double-sided timing belts enabling powerful and reliable solutions across a wide range of power applications in DSTDDouble-Sided Super Torque Drive
Thanks to its involute-shaped geometry, the STD profile achieves optimal meshing of the teeth in the sprocket. As a result, the STD also ensures very precise, low-noise operation even at high belt speeds. The profile is also available in the double-sided DSTD version. (Double-Sided STSSuper Torque Synchronous
STS is an alternative designation for the STD profile used by some manufacturers. Its involute shape allows optimal tooth engagement with the pulley, ensuring precise and quiet operation even at high belt speeds.
The STS, STD or even STPD profiles are compatible with each other and can be used in the same applications.) profiles
Antistatic – for compliance with requirements to ISO 9563.
The trendsetters with less polycyclic aromatic hydrocarbons (PAH) for clean operation and protection of persons in case of long-term contact with the belt.

The involute shape of the STD profile allows optimal tooth engagement with the pulley. As a result, it provides precise and quiet operation even at high belt speeds., CTDConti Torque Drive
The CTD profile is a symbiosis of the HTD and STD profiles, combining the benefits of both tooth geometries. The tooth height and width correspond to that of the HTD profile for transmitting extremely high torques and preventing jump-over at the same time, while the involute-shaped flank ensures very smooth running., GTRThe GTR profile is a symbiosis of the HTD and STD profiles, combining the benefits of both tooth geometries. The tooth height and width correspond to that of the HTD profile for transmitting extremely high torques and preventing jump-over at the same time, while the involute-shaped flank ensures very smooth running. It also incorporates an additional groove in the tooth head, which enables the air to escape gently from the tooth gap, further enhancing its smooth running., H.O.T.Helical Offset Tooth
The helical toothing of the H.O.T. profile delivers a degree of operational smoothness unrivaled by other timing belts The noise level can be reduced by up to 19 dB, and the polygon effect is almost eliminated, resulting in up to 20% lower vibrations. The profile’s offset toothing means the belt is also self-tracking: Flanges are not necessary, as a result of which the width of the system can be reduced., TTrapezoidal/Trapezprofil
The T profile is a trapezoidal standard profile in a metric pitch for conventional timing belt applications. The tooth geometry allows a play-free belt/sprocket pairing that results in unsurpassed precision. and ATThe AT profile is a further development of the T (Trapezprofil) profile. The teeth have a higher load capacity because of the increased tooth volume. The optimized flank angle results in improved tooth meshing. Here, too, a play-free belt/sprocket pairing that results in unsurpassed precision can be achieved. and belts with trapezoidal profiles.
