OVR Polyethylene Tensioning Sliding Blocks
OVR (sliding blocks) are part of the tensioner for tensioning of chains during operation.
They consist of a sliding segment made of special highly resistant and abrasion-resistant plastic and a fastening screw. It is attached to the lever of the universal tensioner with a screw.
It is a universal flexible element that can simultaneously perform the functions of suspension, guidance, tensioning and damping.
