The Ruland rigid shaft coupling is designed for precision alignment applications where zero backlash and secure shaft connections are critical. Machined from durable 1215 lead-free steel with a black oxide finish, this one-piece clamp style coupling provides extra holding power without marring shafts. Its 16 mm bore with keyway ensures accurate and reliable shaft joining for demanding mechanical systems.
Engineered for high performance, this coupling supports up to 200 N·m torque and 4,000 RPM maximum operating speed. Four vibration-resistant alloy steel socket cap screws provide strong clamping force, while precision-honed bores maintain alignment. Ideal for use in timing, joining, and aligning shafts in applications where flexibility is not required.
