Belt Tensioners
York Industries introduces a comprehensive selection of precision-engineered tensioners, essential components employed in synchronous power drives to mitigate belt cogging and slipping, while significantly enhancing belt longevity. With effortless adaptability to varying drive tolerances, our tensioners facilitate precise center distance attainment using standard stock timing belt lengths, simplifying installation and field servicing, even in fractional horsepower systems.
Meticulously manufactured with utmost precision, our tensioners seamlessly integrate with various types of small synchronous drives, owing to their innovative slot and pivot designs. Our comprehensive tensioner range encompasses four distinctive types, each available in two size variations:
York's static tensioners are renowned for their exceptional functionality, ideally suited for power drives with minimal irregular force transmission, where belt stretching and wear are inherently limited. Conversely, dynamic tensioners find extensive application in synchronous drives, adeptly compensating for belt wear through self-adjustment capabilities. These tensioners exhibit superior tolerance for minor installation errors and inaccuracies, simplifying adjustment and replacement procedures.
