RULAND MANUFACTURING Bellows Coupling: 1/4 in Bore Dia 1, 6 mm Bore Dia 2

This clamp-on bellows shaft coupling connects two round shafts with different bore sizes—1/4 inch and 6 mm—in motion-control systems. It compensates for misalignment while transmitting torque, commonly used in precision automation, robotics, and servo-drive applications where zero backlash and high torsional stiffness are required.

This coupling has a 1/4 inch bore on one end and a 6 mm bore on the other, both same bore dimensions. It is made of stainless steel, has a maximum speed of 10,000 RPM, and is designed for inch-to-metric bore transitions. The manufacturer part number is BC12-1/4"-6MM-A.

Select a coupling where one bore matches your inch shaft diameter and the other matches your metric shaft diameter. Ensure the maximum speed rating (here 10,000 RPM) exceeds your application speed. Verify that the coupling material—stainless steel in this model—suits your environment for corrosion resistance and torque requirements.
