The Main Material of Oilless Bushing

Oilless Bushing: Also known as self-lubricating bearing, it is a novel lubricating bearing that combines the characteristics of metal bearings and oil-free lubrication. The metal basically bears the load, and the specially formulated solid lubricating material has the air lubrication effect. It has a strong load-bearing capacity and high resistance. The characteristics of impact, high-temperature resistance, and strong self-lubricating ability are especially suitable for heavy, low speed, reciprocating or swinging occasions where it is difficult to lubricate and form an oil film. It is not afraid of erosion and erosion by water and other acids.

The main material of oil-free bushing

1. Huangli high copper High-power brass is widely used. After casting, it is made into bearing bushes and bushes. At present, it is mainly made of high-power brass in China.

Lubricated oil-free bearings (abbreviated as oil-free bearings) are made of high-strength and high-strength brass as the matrix, and radially embedded cylindrical polymer fillers arranged in an orderly manner as friction materials (generally graphite, molybdenum disulfide, polytetrafluoroethylene) Lubricants such as vinyl fluoride, engine oil, etc.), its superiority is mainly that it enables copper alloys and non-metallic anti-friction materials to have their own complementary advantages, which not only have high load-bearing capacity but also break the limit of ordinary bearings relying on oil film grease lubrication. In addition to oil-free lubrication, the embedded solid lubrication is easy to form a lubricating film, which greatly improves its friction and wear performance, and is stable, reliable, and cost-effective.

2. Tin bronze: bronze with tin as the main alloying element. The tin content is generally between 3 and 14%, which is mainly used to make elastic components and wear-resistant parts. It has high mechanical properties, anti-wear performance and corrosion resistance, easy cutting processing, good brazing and welding performance, small shrinkage coefficient, and non-magnetic. High strength, corrosion resistance and excellent casting performance have been widely used in various industrial sectors for a long time. Tin bronze is the most widely used and used in the electrical and electronic industries, accounting for more than half of the total consumption. Used in various cables and wires, motors and transformers, switches and printed circuit boards. In the manufacture of machinery and transportation vehicles, it is used in the manufacture of industrial valves and fittings, meters, sliding bearings, molds, heat exchangers and pumps.

3. Composite type: It is made of steel plate as the matrix, sintered spherical bronze powder in the middle layer, and rolling a mixture of polytetrafluoroethylene [PTFE] and lead on the surface. It has a small coefficient of friction, wear resistance and corrosion resistance. It is widely used in the sliding parts of various machinery such as printing machines, textile machines, hydraulic pallet trucks, tobacco machines, medicinal machinery, fitness equipment, micro motors, automobiles, motorcycles, etc.
