Bearings • Bushings

A common type of plain bearing, a bushing is typically inserted into a housing to provide a bearing surface for rotary applications. Industrial-style bushings are common within oil field applications, and manufacturing and metal fabricating operations. Bushings are also used in computer, consumer electronics, aerospace, and medical applications. Common bushing designs include solid, (sleeve and flanged), split, and clenched. Solid sleeved bushings are a solid all the way around, while split bushings have a cut along the length of the bushing. Clenched bearings are similar to split bushings, but feature a clench between the halves. Flanged bushings are a sleeve bushing with a flange extending radially outward. Linear bushings are secured with two retaining rings and not pressed into a housing.
