Bellows Clamp Coupling 5/8 in Bore

The Ruland Manufacturing BC26-10-10-A is a motion control coupling designed for precision shaft connections. It suits automation and instrumentation builds where low backlash and high torsional stiffness are required. The clamp-on locking method secures round shafts without marring them. This new component fits inch-system machinery.

Torque Capacity 250 in-lb and 10,000 RPM

Rated for a maximum torque of 250 in-lb and a dynamic non-reversing torque of 125 lb-in, it handles moderate power transmission with a parallel misalignment allowance of 0.01 in. The stainless steel bellows and aluminum hubs operate up to 10,000 RPM. Beyond these limits the coupling will exceed its rated performance envelope.

1.63 in Outside Diameter and 2 in Overall Length

The compact 1.63 in outside diameter and clearance diameter allow installation in tight spaces between bearings or gearboxes. An overall length of 2 in with 0.95 in length through each bore keeps the shaft engagement short. Builders needing larger bore diameters or different bore sizes must select another model. California Proposition 65 warnings apply.

Questions about this item

Will the 1.63 in clearance diameter of this Ruland bellows clamp coupling fit alongside the 5/8 in shafts I already have?

Yes, the coupling has a 5/8 in bore on both ends and a 1.63 in clearance diameter, so it matches your existing shafts directly.

How can I confirm the coupling is running true after installation?

Spin the assembly up to 10,000 RPM and check that parallel misalignment stays within 0.01 in; smooth rotation at that speed shows it is working as intended.

Does the box include the stainless-steel bellows and aluminum hubs already assembled, or do I need to buy any hardware separately?

The coupling ships fully assembled with the stainless-steel bellows and aluminum hubs; no extra components are required for installation.
