Clamping shaft collars, rigid couplings permit precision alignment


Stafford Manufacturing Corp. of Wilmington, Massachusetts, has introduced a full line of shaft collars, mounting collars, and sleeve couplings that provide highly accurate working surfaces and mar-free clamping.

Custom-designed shaft collars and rigid couplings that solve specific mechanical drive or packaging system and conveyor component compatibility issues are available. Stafford custom shaft collars and couplings can be manufactured to precise design requirements from a wide range of materials in a variety of configurations with special bore features such as hex, square, or round shapes and keyways including hinges and threads.  Exterior modifications can include flats, slots, knurls, laser etching, tapped through-holes, flanges, cams, target inserts, levers, and related parts to meet OEM specifications.

Supplied in prototype through production quantities, Stafford custom shaft collars and couplings can be machined from alloy steels, stainless alloys, titanium, aluminum with anodizing in bright colors, brass, bronze, Delrin®, and other materials.  Sizes can range from 1/8” to 12” I.D. with dimensional tolerances of less than 0.001” and less than 0.001” T.I.R. concentricity, depending upon configuration.  3-D models can be provided for proof-of-concept testing.

Stafford Accu-Clamp™ Shaft Collars feature an integral clamp on one side while leaving the other flat and perpendicular within 0.001” TIR to permit mounting next to precision bearings, sprockets, and gears.  For mounting components, Accu-Mount™ and Accu-Flange™ collars have a centering hub with predrilled and tapped holes on their flat side and flange, respectively.

Providing strong, mar-free clamping power, Stafford Accu-Clamp™ Shaft Collars are available made from aluminum, steel, and stainless steel in 0.5” to 2” I.D. sizes.  A Precision one-piece sleeve coupling with a rigid center clamp section and the Accu-Clamp™ feature at each end is offered for a distortion-free coupling with a more precise fit and shaft-to shaft concentricity within 0.001” TIR.

Stafford Accu-Clamp™ Shaft Collars and related components are priced according to size and quantity.  Price quotations are available upon request and custom modifications can be accommodated.
