Designed for large belt and chain drives, these tensioners maintain correct drive tension for smooth operation, maximum power, and a long service life.

Apply continuous tension and automatically take up slack at any point in a 180° arc.

Precisely apply tension in a straight line by moving the adjustment screw.

At less than 4" in height, these tensioners are good for use on low-clearance drives.

Install these rings between strands of chain to absorb slack without the need for realignment, lubrication, or tools—good for use in confined spaces where maintenance may be difficult.
