Ruland SPC-24-16-F Two-Piece Clamping Rigid Coupling with Keyway, Black Oxide Steel, 1-1/2" Bore A Diameter, 1" Bore B Diameter, 2-5/8" OD, 3-7/8" Length, 3/8" x 1/4" 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. 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. In-house proprietary black oxide process produces a fine glossy finish while increasing holding power and resisting corrosion. 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. Opposing screws balance the two-piece coupling to reduce vibration and have higher speed capabilities. All rigid couplings are manufactured from bar stock in our Marlborough, MA factory under strict controls using proprietary processes.

• Precision honed bores for superior fit and torque transmission. Does not mar the shaft. Keyways are used for additional torque transmission capabilities and to prevent slippage on the shaft.
• Two-piece styles have opposing hardware for a balanced design.
• Proprietary Nypatch anti-vibration hardware prevents galling, maintains high holding power, and allows for multiple screw insertions. Nypatch significantly reduces installation time as no additional screw treatment is needed prior to use.
• Made from 1215 lead-free steel with proprietary black oxide finish for increased holding power and corrosion resistance. Machined to a fine burr free finish.
• Hardware exceeds 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.
