Back to Industrial Power Transmission Belt
Super Torque Synchronous (STS) Belts

Features
- High torque capacity drive
Unique tooth profile enables the belt to transmit higher power. - Lower noise level
Smoother tooth engagement and direct contact of tooth top with the pulley grooves enables the belt to run quietly even at high speeds. - Long service life
As the belt tooth meshes with the pulley grooves, the cord layer forms an almost true circle. This minimizes the cantilever effect on the cords, resulting in reduced bending fatigue and longer service life. - No maintenance
No lubrication or retensioning required. - Space saving
Due to higher power transmission capacity, the belt width and the pulley width can be designed more narrowly.
This means machine space can be reduced and the machine can be designed more compactly.
