Bearings • Sleeve Bearings
A type of plain bearing used to reduce friction and increase spin time, sleeve bearings consist of a plastic sleeve that revolves around a metal axle. Sleeve bearings are made of compressed powdered metal - such as bronze or copper - and are found in automobiles, home appliances, fans and office machinery. Bronze sleeve bearings are considered the most widely used sleeve bearing type, and can operate over a wider range of PV valves when compared to other bearing types. While they are self-lubricating, sleeve bearings are often shielded from dust and dirt by applying seals.
