The 40mm x 40mm Stainless Steel (303) Metric Rigid Shaft Coupling Two-Piece Clamp with Keyway is designed to connect two aligned shafts and make them function as one with zero backlash. Its two-piece clamp design completely separates for convenient assembly, installation, and adjustment, while the standard keyway provides added torque capacity and maintains fixed shaft phasing for reliable power transmission. Fully metric in all specifications, including the clamping screws, it offers convenient compatibility with metric machinery. Precision machined with high clamping power, its smooth bore helps protect shafts from damage and provides superior torque capacity compared to set-screw-type couplings. Made from 303 stainless steel, it provides excellent corrosion resistance, strength, and durability for reliable performance in demanding applications.
