Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This RULAND MANUFACTURING clamp-on bellows shaft coupling is used to connect two shafts in motion-control systems, compensating for misalignment while transmitting torque. It is ideal for precision applications such as encoders, stepper motors, and servo drives where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING BCK32-20MM-5/8"-A bellows coupling?

This coupling has a 20 mm bore diameter 1 and a 5/8 in bore diameter 2, with a maximum speed of 10,000 RPM. It is made of stainless steel, has no keyway, and is designed for inch to metric bore applications with same bore dimensions. The manufacturer part number is BCK32-20MM-5/8"-A.

Where to buy RULAND MANUFACTURING bellows couplings worldwide?

You can source RULAND MANUFACTURING bellows couplings worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this coupling.

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

Select a coupling by matching bore diameters to your shaft sizes and ensuring the maximum speed rating exceeds your application's RPM. For keyed shafts, choose a clamp-on style with no keyway if your shafts are keyless. Verify material compatibility—stainless steel suits corrosive environments. Consult RULAND MANUFACTURING's catalog for torque ratings.

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.
