Designed for packaging applications, rigid couplings feature precision honed bores, antivibration hardware, and opposing hardware on two-piece styles to ensure fit, alignment, and holding power. The couplings are suited for shaft-to-shaft connections and servodriven applications as they produce no misalignment, vibration, or bearing noise. Straight-bore rigid couplings have precision honed bores for better fit, torque transmission, and alignment. The coupling’s crosscut design accommodates slight deviations in the size of the shafts being connected for proper fit.

All coupling hardware is Nypatch coated to resist vibration and maintain holding power. It also provides even screw seating, repeated screw installations and prevents galling. Two-piece styles have opposing hardware for balancing, reduced vibration, and higher speed capabilities.

The couplings come in one and two-piece clamp styles with or without keyways in bore sizes ranging from 1/8 to 2 in. (3 to 50 mm) and materials include 1215 lead-free steel, 2024 lightweight aluminum for low inertia, and 303 stainless steel for corrosion resistance.
