Precision Bellows Coupling 3/8 Inch Bore

This Ruland Manufacturing bellows clamp coupling connects two 3/8 inch shafts in motion-control applications. The stainless-steel bellows and aluminum hubs transmit torque while compensating for misalignment. Rated for 10,000 RPM maximum speed and 60 in-lb peak torque. Suitable for precision positioning equipment.

Verify Shaft and Speed Requirements

Confirm both shafts measure exactly 3/8 inch round before ordering. The clamp-on locking method requires clean, burr-free shaft surfaces for proper grip. Ensure your application does not exceed 10,000 RPM or 30 lb-in continuous non-reversing torque. Parallel misalignment capacity is 0.004 inch.

Stainless Bellows and Clamp Hubs

The stainless-steel bellows resists corrosion while providing 0.004 inch parallel misalignment absorption. Aluminum hubs with integral clamps secure each shaft over a 0.63 inch engagement length. Overall length is 1.33 inch with a 1 inch outside diameter. California Proposition 65 warning applies for cancer and reproductive-harm chemicals.

Questions about this item

What comes in the box and do I need any extra hardware to install the BC16-6-6-A coupling?

The coupling ships as a complete clamp-on unit with stainless-steel bellows and aluminium hubs; no additional fasteners or adapters are required for standard 3/8 in round shafts.

How do I decide between the listed torque and speed ratings for my application?

The coupling handles up to 10,000 RPM and 60 in-lb maximum torque, with a non-reversing dynamic torque of 30 lb-in; choose based on whether your peak load stays below the dynamic figure.

What does the 0.004 in parallel misalignment spec mean once the coupling is mounted on a machine?

It allows the two 3/8 in shafts to be offset by up to 0.004 in while still transmitting torque smoothly at speeds up to 10,000 RPM.
