Product Description

The RULAND MANUFACTURING BC12-3-3-A is a clamp-on bellows shaft coupling for round shafts, made of stainless steel with an aluminum bellows. It features two 3/16 inch bores of the same dimension and is designed for inch-sized shafts. This motion control coupling is suitable for applications requiring zero backlash and high torsional stiffness.

Frequently Asked Questions

What is the RULAND MANUFACTURING BC12-3-3-A coupling used for?

The RULAND MANUFACTURING BC12-3-3-A is a clamp-on bellows shaft coupling used in motion control applications requiring zero backlash and high torsional stiffness. It connects two 3/16 inch round shafts of the same diameter, making it suitable for precision positioning systems, encoders, and servo drives.

What are the specifications of the RULAND MANUFACTURING BC12-3-3-A?

The BC12-3-3-A has two 3/16 inch bores of the same dimension, a stainless steel body with an aluminum bellows, and inch-sized shaft compatibility. It is a clamp-on style coupling with no keyway, designed for zero-backlash motion control. The manufacturer part number is BC12-3-3-A.

Where to buy the RULAND MANUFACTURING BC12-3-3-A worldwide?

You can source the RULAND MANUFACTURING BC12-3-3-A through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this motion control coupling.

How to install a RULAND MANUFACTURING clamp-on bellows coupling?

To install the BC12-3-3-A, ensure shafts are clean and aligned within the coupling's specified misalignment limits. Loosen the clamp screws, slide the coupling onto both shafts, then tighten the screws evenly to the manufacturer's recommended torque. Avoid over-tightening to prevent damage to the bellows.
