Machinable Couplings, A Custom Fit Without The Wait

When a coupling connecting two different size shafts fails, what do you do? Especially if the shafts are non-standard diameters? Do you stop your production line and await a specially-made replacement?

A better solution is machinable couplings.

Also known as "re-machinable couplings," machinable couplings are designed with a standard bore size in one end and a pilot hole in the other. So, you can re-machine the pilot to any inch, metric or nonstandard diameter.

Before machinable couplings, the only way to connect two nonstandard shafts or inch shafts with metric shafts was through custom machining. But since only one or two are typically needed at a time, set-up costs were high.

"That's why we devised machinable couplings," explains Dan Whalen, president of Collars and Couplings, Inc. "They're great problem solvers. You're not phoning an OEM for an expensive replacement. You simply order one from a power transmission, industrial supply or fastener distributor and have a machine shop quickly re-bore the part to any shaft dimension in minutes."

"Distributors have a chance to be real heroes to their customers by recommending machinable couplings," continues Whalen. "And they're not temporary fixes. These are regular single-split couplings that have all the load values of couplings made from scratch."

Collars and Couplings offers a full line of single split machinable couplings in steel black oxide without keyways in standard bore sizes from one-half-inch to two-inches. "We have machinable coupling inventory in stock at all times, so distributors can get whatever they need fast. We quote in-stock items in 60 seconds and guarantee same-day shipping of in-stock items ordered by 3 p.m. Eastern Time," says Whalen. Since there are no minimum order requirements, distributors can order as few as one machinable coupling at a time.

Collars and Couplings caters only to wholesalers, primarily power transmission, industrial supply and fastener distributors. End users who try to order are referred by the company to its authorized distributors.

A 100% employee-owned company, Collars and Couplings is an ISO 9001:2000 certified supplier of shaft collars and couplings, including RoHS compliant parts. The company ships orders on the same day and offers custom manufactured specials. For more information, call toll-free 1-800-593-2323 or fax 1-877-474-7005, Monday-Friday 8 a.m. to 5 p.m., or go to
