Shaft couplers come in a variety of styles and sizes. Standard shaft couplings are solid and rigid, but many other varieties exist. A split shaft coupling can provide clamping power that avoids damaging the shaft, while flexible shaft couplings are engineered to carry torque between the inner and outer parts of the coupling

If your business needs parts to join shafts, you can easily find shaft coupling manufacturers online to meet your requirements.
Whether you're looking for a smaller shaft coupling product or heavy duty shaft couplings, follow this blueprint:

1. Buy solid shaft couplings.
2. Purchase flexible shaft couplings to deal with higher torque and avoid backlash.
3. Browse an online catalog featuring multiple varieties of shaft couplings.

Find rigid shaft couplings online

A rigid shaft coupling wraps around the shaft to provide high torsional holding power without damaging the shaft.

I recommend: Ruland sells one- and two-piece solid shaft couplings and offer products made from aluminum, carbon steel and stainless steel. Check out Ruland's online listings for technical specifications and product information. Dayton Superior Products manufactures solid couplings, single and double split couplings, and disengagable couplings. Navigate their website to find product information and cross reference their shaft couplings against other industry brands.

Buy flexible shaft couplings

A flex shaft coupling is designed to transmit torque while at the same time allowing some shaft misalignment. Different varieties of flexible shaft couplings allow for low backlash, reduced vibration and torque transfer.

I recommend: Coupling Corporation of America offers FLEXXOR and UltraFLEXX flexible shaft couplings, which are among the most flexible and reliable shaft couplings available. Its couplings are generally used in high-speed industrial applications. For a variety of flexible shaft couplings, check out the products available from R+W. It offers multiple models of bellows coupling, torque limiters and more.

Find online catalogs featuring multiple shaft coupling models

If you're looking to buy an industrial shaft coupling but aren't sure what variety is best, or if you need to buy an array of different types, check out a manufacturer with a large online catalog. Easily compare prices and models and weigh the benefits of using one shaft coupling over another.

I recommend: Lovejoy offers a variety of jaw, motion control, and gear couplings, as well as specialty couplings and universal joints. View product information and download a full catalog from its website. Zero-Max manufactures a number of motion control products, including shaft couplings designed for high torsional control and backlash limitation.
