Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This RULAND MANUFACTURING bellows coupling is used to connect two keyed shafts of 1 1/4 in diameter in motion-control applications. It compensates for angular, parallel, and axial misalignment while transmitting torque with zero backlash, making it suitable for precision positioning systems, encoders, and servo drives.

What are the specifications of the RULAND MANUFACTURING BCK50-20-20-A bellows coupling?

The RULAND MANUFACTURING BCK50-20-20-A is a clamp-on bellows coupling with 1 1/4 in bore diameter on both ends (same bore dimensions). It is constructed from stainless steel bellows and aluminum hubs, designed for inch-size keyed shafts. The part number is BCK50-20-20-A.

Where to buy RULAND MANUFACTURING bellows couplings worldwide?

You can source RULAND MANUFACTURING bellows couplings worldwide through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the BCK50-20-20-A or other RULAND MANUFACTURING couplings.

How to select a RULAND MANUFACTURING bellows coupling for keyed shafts?

To select a RULAND MANUFACTURING bellows coupling, match the bore diameter to your shaft size (e.g., 1 1/4 in for both ends). Ensure the coupling type (clamp-on) fits your shaft keyway. Consider torque requirements and misalignment tolerance. RULAND MANUFACTURING offers inch and metric sizes; verify the part number BCK50-20-20-A for same-bore applications.

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.
