Unique modified curvilinear tooth form enables the STS belt to transmit greater loads than like-sized drives having the standard high torque tooth profile.
Smoother tooth engagement and direct contact of belt tooth top with the pulley grooves enables the belt to run quietly - even at high speeds.
As the tooth meshes with the pulley grooves, the cord lay forms an almost true circle, minimizing the cantilever effect on the cords, resulting in reduced bending fatigue and longer service life.
No lubrication or re-tensioning required.
Higher HP transmission capability can decrease the belt and pulley width, reducing the drive space envelope, resulting in a more compact machine design.
