Oilite is a brand of self-lubricating bearing that is made from metal alloys with pores that channel lubricants between the bearing itself and the shaft. It is manufactured from different types of material.
Class III: bearings made of materials that are the lubricant. These bearings are typically considered "self-lubricating" and can run without an external lubricant. Examples of the second type of bearing are Oilites and plastic bearings made from polyacetal; examples of the third type are metalized graphite bearings and PTFE bearings. [10]
Frelon is a polytetrafluoroethylene (PTFE) based material with other proprietary fillers to increase bearing characteristics, such as low wear, low friction, and high strength. It is chemically inert and self lubricating. It qualifies as a class III plain bearing. [1]
Graphalloy is the trademark for a group of metal-impregnated graphite materials. [1] The materials are commonly used for self-lubricating plain bearings or electrical contacts. They are proprietary materials owned by the Graphite Metallizing Corp. based in Yonkers, New York, USA.
A ball bearing. A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.
MoS 2, for example, is compounded in materials for sleeve bearings, elastomer O-rings, carbon brushes, etc. Solid lubricants are compounded in plastics to form a "self-lubricating" or "internally lubricated" thermoplastic composite. For example, PTFE particles compounded in the plastic form a PTFE film over the mating surface, resulting in a ...
