The 1-3/4" x 1-3/4" Stainless Steel (303) One-Piece Clamp Rigid Shaft Coupling Low Profile is a precision-engineered coupling designed to join aligned shafts and make them function as a single unit with zero backlash. Its one-piece clamp design provides high clamping power, easy adjustment, and a smooth bore that prevents shaft damage while delivering superior torque capacity compared to set-screw-type couplings. Made from stainless steel which delivers reliable strength, durability, and protection against corrosion. The Low Profile design features a clamp screw that extends beyond the outside diameter (OD), making it suitable for compact shaft connection applications. Ideal for automation systems, motion control equipment, machinery assemblies, and industrial applications requiring secure and accurate shaft alignment. This product is offered in High Strength, Low Profile and Heavy Duty styles and available in steel, stainless steel, and aluminum.
