Self-lubricating bearings are not bearings pre-coated with grease or oil – Graphite Plugged Bronze Bushing that has Solid lubricant in the bearing and flows out little by little due to frictional heat during use.
This kind of Self-lubricating bearings for heavy-duty conditions. Operate the machine smoothly without the need for additional lubricants. It is widely used in automotive product lines, water engineering, dam gate, plastic industries, successive casting machines, steel rollers in the metallurgy industry, mineral machines, ships, turbo generators, hydraulic turbines, and injection molding machines.
An Oilite Bushings – Oil-Impregnated Bronze Bushings
Oilite bushing is a Sinter bronze component with high porosity (20-25% in volume), impregnated in a lubricant oil. The oil contained in the porosity provides a constant lubrication between the bearing and shaft, so the system does not need any additional external lubricant. We manufacture & export an assortment of bearings, bushes, dry bushings, flanged bearings, automotive washers, pump washers, wear plates, and CNC parts.
The Difference Between “Self-Lubricating Bearings” And “Oilite Bushings”
Self-lubricating Bearings VS Oilite Bushings. Bearings are components used to support and also to support the rotating parts on the shaft, Oilite bushings work by impregnating the lubricant into the sliding layer of the bearing. In contrast, self-lubricating bearings are made of graphite impregnated in small holes in the surface of the bushings. When in use, these bushings release the graphite, forming a lubricant film that keeps the machinery running smoothly.
Oilite bushings are metal powder bonded to have 10-40% structural voids; Self-lubricating bearings matrix are centrifugally cast; the matrix density is relatively high, bond strength is relatively high compared to oil-impregnated bearings, and the operating life is longer than oilite bearings;
The slick material of oilite bushings is lubricant oil, and the oil film has a satisfying thickness that eliminates direct contact between the two conflicting surfaces. the conflict coefficient is very small (f = 0.001 ~ 0.008), significantly reducing the conflict and wear;
self-lubricating bearings smooth material is solid lubricant material, even in oil-free working conditions, can still go an excellent smooth effect, can ensure that the smooth does not stop and is sustainable, its useful smooth life with the life of the substrate;
Oil-impregnated bearings within the lubricant oil with volatile and easy-to-lose sex, when in high temperature and high-pressure loss accelerated, can not get due smooth role;
Self-lubricating graphite copper bushing, In the friction process, in the conflict surface to form a smooth excellent, strong attached, and uniformly covered solid carry film, substantially reducing the conflict wear. With the conflict, the solid lubricant embedded in the holes continuously supplies, to ensure a long time operation of the conflict vice excellent smooth.
