Product Description

This RULAND MANUFACTURING Bellows Coupling is a clamp-on bellows shaft coupling for round shafts with a 1 3/4 in bore diameter on both ends (same bore dimensions). It is made of aluminum with stainless steel bellows and has an inch measurement system. The coupling is designed for applications requiring zero backlash and high torsional stiffness.

Frequently Asked Questions

What is the RULAND MANUFACTURING BC50-28-28-A bellows coupling used for?

This RULAND MANUFACTURING bellows coupling is used for precision motion control applications requiring zero backlash and high torsional stiffness. It connects two round shafts of the same 1 3/4 in diameter in servo motors, encoders, and linear actuators where accurate torque transmission is critical.

What are the specifications of the RULAND MANUFACTURING BC50-28-28-A coupling?

The BC50-28-28-A is a clamp-on bellows coupling with 1 3/4 in bore diameter on both ends (same bore dimensions). It is made of aluminum with stainless steel bellows, uses an inch measurement system, and has no keyway. The manufacturer part number is BC50-28-28-A.

Where to buy the RULAND MANUFACTURING BC50-28-28-A coupling worldwide?

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.
