Product Description

This RULAND MANUFACTURING Bellows Coupling is a clamp-on bellows shaft coupling for keyed shafts with a 45 mm bore diameter 1 and a 1 3/4 in bore diameter 2. It is made of stainless steel, has a maximum speed of 10,000 RPM, and features different bore dimensions for inch to metric bore applications.

Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This RULAND MANUFACTURING bellows coupling connects two shafts with different bore sizes—45 mm and 1 3/4 in—in motion-control systems. It compensates for misalignment while transmitting torque, making it suitable for precision positioning, encoders, and servo drives in industrial automation.

What are the specifications of the RULAND MANUFACTURING BCK50-45MM-1-3/4"-A bellows coupling?

This clamp-on bellows coupling has a 45 mm bore diameter 1 and a 1 3/4 in bore diameter 2, with a maximum speed of 10,000 RPM. It is made of stainless steel, features different bore dimensions for inch-to-metric applications, and is designed for keyed shafts.

Where to buy a RULAND MANUFACTURING bellows coupling worldwide?

3G Electric supplies and delivers the RULAND MANUFACTURING BCK50-45MM-1-3/4"-A bellows coupling worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to ensure your order reaches any international destination.

How to select a bellows coupling for keyed shafts?

Select a bellows coupling by matching bore diameters to your shaft sizes—here 45 mm and 1 3/4 in—and verifying max speed (10,000 RPM) and torque requirements. Ensure the coupling material (stainless steel) suits your environment. For keyed shafts, confirm the coupling includes a keyway.

Used in

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.
