Couplings, collars & universal joints are used to transmit power and prevent shocks, vibrations, overloads, backlash errors or misalignments. Raptor Supplies offers a broad range of these connectors from brands like Ruland Manufacturing, Lovejoy, Climax Metal Products and Dayton. The jaw couplings and sleeve or tire couplings are ideal for use with electric motors and need no lubrication. While the motion control couplings deliver excellent rigidity in moderate & high torque applications, the rigid ones provide minimal backlash errors between shafts in continuous-duty jobs.
