The 35mm x 35mm Stainless Steel (303) Metric Three-Piece Clamp Coupling with Keyway is designed to securely connect two aligned metric shafts, allowing them to function as a single unit with zero backlash for precise torque transmission. Its fully metric design, including metric clamp screws, ensures compatibility with metric shafting and equipment. The integrated keyways provide added torque capacity and fixed shaft phasing, while the three-piece clamp design keeps one shaft securely in place as the other is moved or replaced for easy installation and maintenance. Precision-machined from 303 stainless steel, it features a smooth straight-through bore that protects shaft surfaces from damage, along with a non-marring clamp mechanism and high clamping force for a secure and reliable connection.
