Nylon Bushings
Description
Nylon Bushings are still considered as an important plastic component. In its bulk form it is very wear resistant, particularly if oil-impregnated, and so is used to build gears, bearings, bushings, and because of good heat-resistance and insulation, increasingly for under-the-hood applications in cars, and other mechanical parts. Bushings must be used coordinated with thermal insulator pad.
