Oilite Plus is the same bronze alloy as an Oilite, impregnated with turbine oil and fine particles of polytetrafluoroethylene (PTFE). This reduces the friction by approximately 17% versus standard Oilite material. This material is usually used in applications that exhibit mixed-film or boundary condition lubrication.
The materials are commonly used for self-lubricating plain bearings or electrical contacts. ... Graphalloy bronze: Bronze: Tensile strength: 5,500 psi (38 MPa ...
Glacier developed the industry's first metal-polymer bearing with bronze and polytetrafluoroethylene (PTFE) lining; these DU® self-lubricating bushes, launched in 1956, are still being manufactured, specified and used today, and its DX® marginally-lubricated bearings, introduced in 1965, are still specified and used for applications where a ...
Self-lubricating plain bearings have a lubricant contained within the bearing walls. There are many forms of self-lubricating bearings. The first, and most common, are sintered metal bearings, which have porous walls. The porous walls draw oil in via capillary action [34] and release the oil when pressure or heat is applied. [35] An example of ...

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 ...
