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.
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.
As with standard roller chains, self-lubricating roller chains consist of five basic parts: inner plates, outer plates, pins, bushes, and rollers. However, the bushes for self-lubricating chains are sintered metal, produced using powder metallurgy. Self-lubricating chains can be manufactured cheaply, quickly, and to precision tolerances. [8]
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]
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 ...
