Flexgrip Coupling

Ideally suited for high-speed, heavy-duty applications, Flexgrip can be used for round belts of leather, urethane, or rubber type compounds. Flexgrip couplings are internally threaded and screw on to belt ends, eliminating the punching of holes necessary with other methods. One end is “closed” and the other is “open.”


The design facilitates easy installation and precise adjustment of belt tension. Flexgrip couplings can be used on belts from 3/16" (4.5mm) to 1/2" (12.5mm). First, determine the size specifications.

Flexgrip couplings for round belts incorporate a true universal joint in their design, which provides smooth, sure operation through multi-directional turns.
