Why oil-free bearings are widely used

Author:admin   Date:2022-06-09
Oil-free bearing is a novel lubricating bearing that combines the characteristics of metal bearing and oil-free lubricating bearing. Widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines. So, why are oil-free bearings widely used?

1. The advantages of oil-free bearings As we all know, all machinery must use a certain kind of bearing for the smooth operation of the machine. Oil-free bearing is a novel lubricating bearing that combines the characteristics of metal bearing and oil-free lubricating bearing. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, strong self-lubricating ability, etc. It is especially suitable for heavy load, low speed, reciprocating or swinging and other occasions that are difficult to lubricate and form an oil film, and it is not afraid of water and other acid erosion. and scour. The majority of users generally reflect that the embedded bearing not only saves oil and energy, but also has a longer working life than ordinary sliding bearings.

2. Oil-free bearing The product is made of steel plate as the base, sintered spherical bronze powder in the middle layer, and a mixture of PTFE and lead rolled on the surface layer. It has the characteristics of small friction coefficient, wear resistance, corrosion resistance, oil-free self-lubrication and long service life. Using it can reduce costs, reduce noise, and prevent sticking and slipping.

3. Metal-based solid inlaid oil-free bearings. A high-performance solid lubricant product of inlaid graphite and MoS2 composite solid lubricant on a metal substrate. It breaks through the limitation of general bearings relying on oil film lubrication. During use, the solid lubricant rubs against the shaft through frictional heat, forming an excellent condition for oil and powder to coexist and lubricate, which not only protects the shaft from wear, but also makes the solid lubricating properties eternal. Its hardness is twice as high as that of ordinary copper sleeves, and its wear resistance is also twice as high. At present, it has been widely used in metallurgical continuous casting machines, train supports, steel rolling equipment, mining machinery, ships, gas turbines and other occasions with high temperature, high load, low speed and heavy load.

4. Multi-layer composite oil-free bearing. The steel plate is used as the base, the spherical bronze powder is sintered in the middle, and the mixture of PTFE and lead is rolled on the surface. It is a rolled sliding bearing. It has the characteristics of small friction coefficient, good wear resistance, good corrosion resistance and oil-free lubrication. It can reduce cost, reduce mechanical volume, avoid shaft bite phenomenon and reduce mechanical noise. Products have been widely used in sliding parts of various machinery, such as printing presses, elevators, textile machines, tobacco machines, fitness equipment, hydraulic trucks, micro motors, solenoid valves, automobiles, motorcycles and household machinery. Oil-free bearings continue to be widely used according to their advantages.

Specializing in manufacturing sliding bearing series products, the physical production enterprises have reached 150 million sets of production capacity, with one automatic sintering line. Enterprise technology relying on Research Institute and colleges and universities and colleges and universities and colleges and universities, constantly develop self-lubricating bearing products adapted to different working conditions and various mechanical fields. The product performance has reached the level of foreign products of the same kind. The sales of products all over more than 40 countries and regions at home and abroad, and have been recognized by domestic and foreign users. In 2006, the company passed the ISO9001 quality system certification! And there is TUV system certification!

The main products are (Du) oil-free bearings, (Dx) boundary lubrication bearings, bronze bush , bronze rolling bearings, self-lubricating bearings. The characteristic product is Du thin wall series!
