CRESA Serie – Automatic Chain or Belt Rotation Tighteners

Maintenance-free tensioning of belts and chains. The CRESA-series is a line of automatic chain or belt tighteners that work in rotation and use the elastic deformation of four natural rubber cylinders. The rubber parts are placed in the four cavities created by two square-section parts rotated at 45° to each other. The maximum angle of torsion that the lever can reach is ±30° from the rest position.

The CRESA base elements are manifold and can also be used as shock absorbers, decelerators or vibrating elements.
