Product Description

The RULAND MANUFACTURING Bellows Coupling (MPN BC44-1-1/4"-25MM-A) is a clamp-on bellows shaft coupling for round shafts, made of stainless steel. It features different bore dimensions: a 1 1/4 in bore diameter on one side and a 25 mm bore diameter on the other, enabling inch-to-metric bore connections. This coupling has a maximum speed of 10,000 RPM.

Supplied to the Philippines — compatible with 60 Hz installations. DHL Express delivery to Manila, Quezon City, Cebu, customs and duties handled door-to-door.

Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This stainless steel clamp-on bellows coupling connects two shafts with different bore sizes — a 1 1/4 in and a 25 mm — enabling inch-to-metric transitions. It handles misalignment and transmits torque in motion-control, packaging, and automation equipment at speeds up to 10,000 RPM.

What are the specifications of the RULAND MANUFACTURING BC44-1-1/4"-25MM-A?

The RULAND MANUFACTURING BC44-1-1/4"-25MM-A is a stainless steel bellows coupling with a 1 1/4 in bore on side one and a 25 mm bore on side two. It has a maximum speed of 10,000 RPM and uses a clamp-on design for round shafts. The part number is BC44-1-1/4"-25MM-A.

Where to buy a RULAND MANUFACTURING bellows coupling worldwide?

3G Electric supplies and delivers the RULAND MANUFACTURING BC44-1-1/4"-25MM-A bellows coupling worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to ensure your order arrives at your facility, wherever it is located.

How to select a bellows coupling for inch-to-metric shaft connections?

Select a coupling like the RULAND MANUFACTURING BC44-1-1/4"-25MM-A that matches each shaft bore diameter exactly — one side in inches, the other in millimeters. Ensure the coupling's maximum speed (10,000 RPM here) exceeds your application's operating speed, and choose stainless steel for corrosion resistance.
