General Information

Tensioning elements and sprockets make up a complete, ready-to-install, continually-tensioning torsion chain tensioner

Suitable for tensioning all common kinds of chain and belt drives

Prolongs the service life of chain and belt drives by at least 30% with notable noise reduction

Long tensioning distance, especially as the lever can be pre-tensioned by up to 30°

Permanent torsion force automatically compensates the chain elongation

Chain track adjustable: Sprocket can be aligned with the chain

Tensioning pressure steplessly adjustable from “normal” to “hard”

Can be used for both tensioning directions

Tensioning elements, sprockets and tensioning rollers have to be ordered separately

Suitable for:

Sprocket sets (Cat. No. 700613 ff)

Chain rider sets (Cat. No. 700621 ff)

Tensioning rollers for timing belts (Cat. No. 702727 ff)
