RULAND MANUFACTURING Bellows Coupling: 20 mm Bore Dia 1, 3/4 in Bore Dia 2

This clamp-on bellows shaft coupling connects two shafts with different bore sizes—20 mm and 3/4 in—in motion-control systems. It compensates for misalignment while transmitting torque at speeds up to 10,000 RPM. Common applications include servo motors, encoders, and precision positioning equipment where zero backlash and high torsional stiffness are required.

The BCK26-20MM-3/4"-A is a stainless steel bellows coupling with a 20 mm bore diameter 1 and a 3/4 in bore diameter 2. It has a maximum speed of 10,000 RPM, features same bore dimensions, and is designed for inch to metric bore applications. The coupling is clamp-on style for keyed shafts and is manufactured by RULAND MANUFACTURING.

3G Electric supplies RULAND MANUFACTURING bellows couplings worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the BCK26-20MM-3/4"-A or other RULAND MANUFACTURING shaft couplings.

Select a bellows coupling by matching bore diameters to your shaft sizes—here 20 mm and 3/4 in—and ensuring the maximum speed rating (10,000 RPM) exceeds your application speed. Verify shaft keyway dimensions and choose stainless steel for corrosion resistance. RULAND MANUFACTURING couplings offer zero-backlash performance for precision motion control.
