Product Description

The RULAND MANUFACTURING BC26-12-12-A is a clamp-on bellows shaft coupling for round shafts, featuring a 3/4-inch bore diameter on both ends (same bore dimensions) and constructed with stainless steel. This inch-series motion control coupling is designed for precision positioning applications requiring zero backlash and high torsional stiffness.

Frequently Asked Questions

What is the RULAND MANUFACTURING BC26-12-12-A coupling used for?

The RULAND MANUFACTURING BC26-12-12-A is a clamp-on bellows shaft coupling used in precision motion control applications. It connects two 3/4-inch round shafts in servo motors, encoders, and linear actuators where zero backlash and high torsional stiffness are required for accurate positioning.

What are the specifications of the RULAND MANUFACTURING BC26-12-12-A?

The BC26-12-12-A has a 3/4-inch bore diameter on both ends (same bore dimensions), is made of stainless steel, and uses a clamp-on design. It is an inch-series motion control coupling from RULAND MANUFACTURING, designed for zero backlash and high torsional stiffness in precision systems.

Where to buy the RULAND MANUFACTURING BC26-12-12-A worldwide?

You can source the RULAND MANUFACTURING BC26-12-12-A through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring the coupling reaches your facility reliably.

How to install a clamp-on bellows coupling like the BC26-12-12-A?

To install the BC26-12-12-A, clean both shaft ends and the coupling bores. Loosen the clamp screws, slide the coupling onto the shafts, align the equipment, then tighten the screws evenly to the manufacturer's torque specification. Avoid over-tightening to prevent shaft damage.
