Self-lubricating Oilite Bushings

The substrate of oilite bronze bushings is processed into a porous structure with a certain degree of permeability and then impregnated with a suitable lubricant (generally with lubricating oil) to fill the pores of the substrate with lubricant and store it. It has the advantage of self-lubrication.

Rolling Bearings VS Oilite Bushing

Compared with rolling bearings, porous oilite bronze bushings has the characteristics of low noise, small size, simple structure, excellent production process, no heat glue, cheap, suitable for mass production, etc.

Oilite Bearing Is Mainly Used In Low Load, Low Speed, Difficult Oil Supply And Avoid Lubricating Oil Pollution.

Tractors, due to the dusty working environment, require the wearing parts to have good anti-abrasive wear characteristics and want the parts to maintain good lubrication conditions in operation as much as possible with a view to achieving a longer service life. Therefore, the application of oilite bushings in tractors is very valuable.

It mainly shows a low coefficient of friction, self-lubricating performance, not easy to scrape and bite in operation, and high load-bearing capacity.

Sinter Bronze bushings can also be dipped in sulfur, plastic, and other solid lubricants to further improve their performance.

Iron Oilite Bearing

Iron-based oilite bearings have higher strength. It has less wear, low production costs, and can withstand larger loads, but it “has anti-seize and corrosion resistance than copper-based oil bearings. Therefore, iron-based oilite bearings are mostly used in mining machinery, agricultural machinery, machine tools, automobiles, and other places where the load is large and the speed is not high.

Copper Oilite Bushes

The copper-based oilite bushes are mostly used in instruments, control motors, household appliances, chemical machinery, etc., where the structure is compact, the load is small, the speed is high, the noise is low or the environment is humid and corrosive.

Oilite Bronze Bushing In Automotive Applications

Because of its wear-reduction performance, corrosion resistance, and high electrical conductivity. They are used more in industries such as home appliances and automobiles. One of the most used is porous sintered bronze.

Applications In Micromotors

Many motors use rolling bearings because of the high noise, high cost, or refueling problems that can not be solved, for the performance of the finished product, and producion, must be changed to oil-containing bearings.

Copper oilite bronze bushings are mostly used in general-purpose motors such as fan motors, jukebox motors, agricultural sprayer motors, etc., which can be set up with oil-filled mechanisms, while micro-motors such as cassette recorder drive motors, color TV motors, etc., which have special low-noise requirements and are inconvenient to refuel, need to be manufactured with electrolytic copper powder to improve the oil content and obtain a diffuse and uniform fine porosity structure.
