Clamp Style Universal Joints – Pacific International Bearing Products

A clamp style universal joint is a U-joint with clamping hubs instead of set screws. The clamp wraps around the shaft and tightens uniformly, creating a secure, non-marring connection that’s easy to install and adjust.

Because the hub clamps evenly around the shaft rather than biting into it with a set screw, it reduces the risk of shaft damage, fretting, or raised burrs. This is especially important on precision-ground shafts and applications where components are repositioned or serviced frequently.

Clamp style U-joints are offered in alloy steel for high torque applications and stainless steel for corrosion resistance. Standard bore sizes range from 1/4″ to 1-1/4″, covering many common shaft diameters in industrial and motion control equipment.

Yes. Anti-vibration hardware is included to help resist loosening under dynamic loads, contributing to stable operation and reduced maintenance in high-speed or high-cycle systems.

Optional protective boots packed with grease are available to seal the joint, retain lubrication, and shield it from contaminants. Using a booted design can significantly extend service life in dusty, wet, or otherwise harsh environments.

These joints are ideal for precision motion control and high-performance power transmission applications where easy installation, infinite adjustability, and shaft protection are priorities, such as packaging equipment, automation systems, medical devices, test stands, and general industrial machinery.

Choose clamp style when you need:

• Non-marring shaft connections
• Quick, repeatable positioning or frequent adjustment
• Extra holding power and resistance to slip under reversing loads

A clean, balanced connection for precision drives
