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.

igus produces maintenance-free, plain, plastic bearings that come in more than 8,000 imperial and metric sizes and are lubrication-free, waterproof, and suitable for temperatures up to 482 degree Fahrenheit. The most popular styles include the M250 which has a coefficient of friction of 0.1 to 0.3, PSI of 2,901, maximum PV of 3,400, and is high-impact resistant. Others include the iglide J (chemical-resistant), R (low moisture absorption), A200 (abrasion-resistant), G300 (vibration-dampening), and L280 (for soft shaft materials). The company also manufactures Drylin linear bearings and iglubal spherical bearings.
