Product Description

This RULAND MANUFACTURING Bellows Coupling is a clamp-on bellows shaft coupling for keyed shafts with a 1 1/2 in bore diameter on one side and a 30 mm bore diameter on the other, accommodating different bore dimensions. It is made of stainless steel, includes a keyway, and is rated for a maximum speed of 10,000 RPM. The coupling features an inch to metric bore configuration, making it suitable for connecting shafts of different measurement systems.

Frequently Asked Questions

What is a RULAND MANUFACTURING bellows coupling used for?

This RULAND MANUFACTURING bellows coupling connects two shafts with different bore sizes—1 1/2 in and 30 mm—in applications requiring precise torque transmission and misalignment compensation. It is commonly used in motion control, packaging, and automation equipment where zero backlash and high torsional stiffness are critical.

What are the specifications of the RULAND MANUFACTURING BCK50-1-1/2"-30MM-A bellows coupling?

This coupling has a 1 1/2 in bore on one side and a 30 mm bore on the other, both with keyways. It is made of stainless steel, rated for 10,000 RPM maximum speed, and features an inch-to-metric bore configuration. The clamp-on design secures shafts without marring.

Where to buy RULAND MANUFACTURING bellows couplings worldwide?

3G Electric supplies RULAND MANUFACTURING bellows couplings worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on the BCK50-1-1/2"-30MM-A or other RULAND MANUFACTURING couplings.

How to install a clamp-on bellows coupling for keyed shafts?

To install, clean both shaft ends and the coupling bores. Align the shafts, slide the coupling onto each shaft, and tighten the clamp screws evenly to the manufacturer's torque specification. Ensure the key is seated properly in the keyway. Check alignment with a dial indicator before final tightening.
