Ruland CLX-3-3-F One-Piece Clamping Rigid Coupling, Black Oxide Steel, 3/16" Bore A Diameter, 3/16" Bore B Diameter, 9/16" OD, 7/8" Length

Only manufacturer with precision honed bores on straight bore rigid couplings for superior fit and torque transmission and alignment. Ruland rigid couplings do not introduce misalignment, vibration, or bearing noise into the system making them suitable for high precision servo applications and shaft to shaft connections. Highest grade forged screws test beyond industry standards for maximum torque ability. Proprietary Nypatch coating on hardware provides even seating of the screw, repeated screw installations and prevents galling. Nypatch hardware also resists vibration and maintains holding power. The cross cut design ensures a proper clamp on both shafts because it can accommodate slight deviations in the size of the shafts being connected. All rigid couplings are manufactured from bar stock in our Marlborough, MA factory under strict controls using proprietary processes.

• Precision honed bores on straight bore couplings for superior fit and torque transmission.Does not mar the shaft
• Proprietary Nypatch anti-vibration hardware prevents galling, maintains high holding power, and allows for multiple screw insertions
• 1215 lead-free steel with proprietary black oxide finish for increased holding power and corrosion resistance
• Hardware tests beyond ANSI standards for maximum torque capabilities
• Ruland rigid couplings are carefully made from select North American bar stock in our Marlborough, Massachusetts factory and are RoHS3 and REACH compliant
