Product Description

The RULAND MANUFACTURING Bellows Coupling (MPN BCK26-12-12-A) is a clamp-on bellows shaft coupling for keyed shafts, featuring a 3/4 in bore diameter on both ends and a maximum speed of 10,000 RPM. Constructed from stainless steel, this inch-series coupling accommodates different bore dimensions and includes a keyway.

Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

A RULAND MANUFACTURING bellows coupling, like the BCK26-12-12-A, is used to connect two rotating shafts while compensating for misalignment. It is ideal for precision motion control applications such as encoders, stepper motors, and servo systems where zero backlash and high torsional stiffness are required.

What are the specifications of the RULAND MANUFACTURING BCK26-12-12-A bellows coupling?

The RULAND MANUFACTURING BCK26-12-12-A is a stainless steel clamp-on bellows coupling with 3/4 in bore diameters on both ends, a maximum speed of 10,000 RPM, and a keyway for keyed shafts. It accommodates different bore dimensions and is an inch-series design.

Where to buy a RULAND MANUFACTURING bellows 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.
