The 1-3/4" x 1-1/2" Stainless Steel (303) Two-Piece Clamp Rigid Shaft Coupling High Strength is engineered to securely connect two aligned shafts, creating a rigid, zero-backlash connection for precise torque transmission and accurate rotational performance. Its two-piece clamp design allows the coupling to be completely disassembled, making installation, maintenance, and shaft adjustments quick and convenient without requiring the movement of surrounding components. Precision-machined with a smooth bore available in either straight-through or stepped configurations, it provides a secure, non-marring grip that protects shaft surfaces while delivering high clamping force for dependable performance. The High Strength design features recessed clamp screws that remain flush with the coupling's outside diameter, reducing the risk of interference with nearby equipment while maintaining a compact, durable profile. This coupling is offered in High Strength, Low Profile and Heavy Duty styles. Stocked in steel, stainless steel, and aluminum.
