What conditions should the bearing bush meet for a sliding bearing

Author:admin   Date:2022-07-29
The bearing bush is on the bearing, the part directly in contact with the shaft, which bears the load and has relative motion with the shaft. In order to reduce friction and wear, various requirements are placed on the bearing material. In addition to requiring a small friction coefficient between the friction pairs and wear resistance, the following points should also be met:

1. It should have sufficient compressive strength, fatigue strength and ability to withstand impact. Bearing alloy thickness is (0.013-0.13) mm.

2. Good anti-adhesion. When the load is large, the rotation speed is high, the bearing clearance is too small, the surface finish is not high, and the lubrication is poor, attention should be paid to carefully selecting the matching of materials to prevent the friction pair from being glued and worn.

3. The bearing bush of the sliding bearing has adaptability and the ability to accommodate foreign bodies. Materials with low hardness, good plasticity and low modulus of elasticity have good adaptability and the ability to accommodate foreign bodies.

4. The bearing bush of the sliding bearing has good corrosion resistance, low price and sufficient sources. After the colloidal deposit is formed by oxidation, it has a corrosive effect on the bearing material. Sliding bearings are widely used.

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, bimetal series bearings, bronze rolling bearings, sleeve bush. The characteristic product is Du thin wall series!
