Together with a chain tensioner set, sprocket set or a tension pulley, the clamping element makes a ready-to-install tensioning unit suitable for tensioning chain and belt drives. Suitable for both tensioning directions. The clamping elements are maintenance-free and tear-off resistant.

The clamping element is fastened to the machine component with a screw. If necessary, a heavy-duty dowel pin can be inserted in the positioning notch “P” for torque support.
