UC Jaw Type Coupler
Chose the Jaw Coupling that meets your jack or system requirements. Gear couplings are also available and are recommended for larger capacity ad reversing applications. Couplers offer standard shaft-to-shaft connection for general industrial-duty applications. Coupler will still perform if elastomer fails. Sintered iron jaws provide reliable service for heavy-duty applications. Wide ambient temperature range: -30° to 160° F. Maximum angle offset of 1 degree - allowing easy installation.
