Spherical Ball Bushings
Spherical Ball Bushings are used to accommodate shafts or rods with variable amounts of misalignment. They are designed to manage high radial loads and provide consistent performance under conditions of marginal lubrication, extreme speed and critical stress. Most spherical ball bushings consist of a plain bearing and ball bushing inside a lined, cylindrical housing that reduces friction or provides lubrication. Lubrication-free spherical ball bushings are also available. Metal balls and liners are usually made of bronze, steel or iron. Non-metallic balls and liners are typically made of nylon, plastic or polytetrafluoroethylene (PTFE). For heavy-duty applications, spherical ball bushings can include large bores or spherically shaped rollers that permit axial loading and relative misalignment between.
