The 1-1/2″ x 1-1/2″ Stainless Steel (303) One-Piece Clamp Rigid Shaft Coupling with Keyway – Low Profile is designed to join two aligned shafts with zero backlash for precise torque transmission and accurate shaft alignment. Its one-piece clamp design features standard keyways for increased torque capacity and fixed shaft phasing, while the smooth bore provides a secure, non-marring grip that protects shaft surfaces.The high-strength design keeps the clamp screw flush with the outside diameter for improved strength and a compact profile.

This coupling is available in two styles: High Strength, featuring a clamp screw that remains within the outside diameter (OD), and Low Profile, featuring a clamp screw that extends beyond the OD. Stocked in steel, stainless steel, and aluminum.
