Product Description

The RULAND MANUFACTURING BC21-8-5-A is a clamp-on bellows shaft coupling for round shafts, featuring a 1/2 in bore diameter on one end and a 5/16 in bore diameter on the other. Constructed with a stainless steel bellows and an aluminum hub, this inch-series coupling accommodates different bore dimensions and is designed for motion control applications.

Frequently Asked Questions

What is a RULAND MANUFACTURING BC21-8-5-A bellows coupling used for?

The RULAND MANUFACTURING BC21-8-5-A is a clamp-on bellows shaft coupling used in motion control applications to connect two round shafts with different bore diameters (1/2 in and 5/16 in). Its stainless steel bellows compensates for misalignment while transmitting torque smoothly in precision machinery.

What are the specifications of the RULAND MANUFACTURING BC21-8-5-A?

The BC21-8-5-A has a 1/2 in bore diameter on one end and a 5/16 in bore diameter on the other. It features a stainless steel bellows and an aluminum hub, is inch-series, and accommodates different bore dimensions. The manufacturer part number is BC21-8-5-A.

Where to buy a RULAND MANUFACTURING BC21-8-5-A coupling worldwide?

3G Electric supplies the RULAND MANUFACTURING BC21-8-5-A clamp-on bellows coupling worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to deliver this motion control coupling to your facility, regardless of location.

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

To install the BC21-8-5-A, align the two shafts and slide the coupling over both ends. Tighten the clamp screws evenly to the manufacturer's recommended torque using a hex key. Ensure shafts are clean and free of burrs to avoid damaging the stainless steel bellows.
