RULAND MANUFACTURING Bellows Coupling: 1/4 in Bore Dia 1, 5 mm Bore Dia 2

This clamp-on bellows shaft coupling connects two round shafts with different bore sizes—1/4 inch and 5 mm—in motion-control systems. It is ideal for precision applications requiring zero backlash, such as encoders, stepper motors, and servo drives, where misalignment compensation and high torsional stiffness are critical.

The coupling has a 1/4 in bore diameter 1 and a 5 mm bore diameter 2, with a maximum speed of 10,000 RPM. It is made of stainless steel, features a clamp-on design for round shafts, and supports inch-to-metric bore applications with same bore dimensions. The manufacturer part number is BC12-1/4"-5MM-A.

3G Electric supplies the RULAND MANUFACTURING Bellows Coupling BC12-1/4"-5MM-A worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location.

To install, slide the coupling onto both shafts, ensuring the bores align with the shaft ends. Tighten the clamp screws evenly using a torque wrench to the manufacturer's recommended torque value. Avoid over-tightening, which can damage the bellows. Verify shaft alignment within the coupling's rated misalignment limits for optimal performance.
