Easy-Ten Type S Chain Tensioner with Polyamide Roller, 30

The Easy-Ten Type S chain tensioner with polyamide roller carries a polyamide roller in place of a sliding block or sprocket.

The roller bears on the chain on the slack side of the drive and the tensioner takes up slack as the chain wears and lengthens.

Key specifications

Choosing the right option

Choose the roller size from the dimensions in the specifications, checking that the roller width suits the chain you are tensioning. The heavy tension box is the standard setting and a light tension box, ET-SNUL, as an option. See the Easy-Ten ET-SNUL Type S light tension box.

Spring force ranges are over the 40mm stroke. The tensioner is supplied in high tension unless low tension is specified.

Fit the tensioner on the slack side of the chain with the roller bearing on the chain. Check the chain tension and the roller at regular maintenance intervals.
