Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This clamp-on bellows coupling connects two round shafts in motion-control applications, compensating for misalignment while transmitting torque. It is commonly used in servo motors, encoders, and precision positioning systems where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING BC21-1/2"-10MM-A bellows coupling?

This coupling has a 1/2 in bore diameter on one side and a 10 mm bore diameter on the other, making it an inch-to-metric bore adapter. It is made of stainless steel, has a maximum speed of 10,000 RPM, and features a clamp-on design for secure shaft attachment.

Where to buy RULAND MANUFACTURING bellows couplings worldwide?

3G Electric supplies RULAND MANUFACTURING bellows couplings worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the BC21-1/2"-10MM-A or other RULAND MANUFACTURING couplings.

How to select the correct RULAND MANUFACTURING bellows coupling for inch-to-metric shafts?

Measure both shaft diameters accurately: one in inches and the other in millimeters. Ensure the coupling's bore sizes match your shafts exactly. For the BC21-1/2"-10MM-A, the inch bore is 1/2 in and the metric bore is 10 mm. Verify speed and torque requirements do not exceed the coupling's 10,000 RPM rating.

Common applications for RULAND MANUFACTURING
Automated packaging machinery — Ruland beam couplings (e.g., PSR20-8-5-A) for connecting servo motors to conveyor drive shafts.
CNC machine tools — Ruland rigid couplings (e.g., CLX-4-4-A) for precise alignment of ball screw assemblies.
Robotic arm joints — Ruland Oldham coupling hubs (e.g., OSC16-6-A) for accommodating axial motion in end-effector drives.
Pump and compressor systems — Ruland stainless steel shaft collars (e.g., CL-3-ST) for securing impeller shafts.
Printing press rollers — Ruland clamp-on beam couplings (e.g., PCR18-8-8-A) for synchronizing roller rotation with minimal backlash.
Material handling conveyors — Ruland set screw couplings (e.g., PSMR29-7-7-A) for linking gearboxes to drive rollers.
