Ruland SCC-6-6-SS Set Screw Rigid Coupling with Keyway, Stainless Steel, 3/8" Bore A Diameter, 3/8" Bore B Diameter, 7/8" OD, 1-3/8" Length, 3/32" x 3/32" Keyway Width

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. 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
• Forged screws are used as opposed to broached for increased durability
• Keyways are used for additional torque transmission capabilities and to prevent slippage on the shaft
• 303 stainless steel with hardware of like material for high 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
