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

CONTI SYNCHROTWIN CXP
