Bearing Wear Resistance
- Oct 24, 2017 -

Sliding bearing, as the name suggests, is actually working under sliding friction. The sliding bearing has the characteristics of smooth work, reliable and noiseless. It is precisely because of some characteristics of sliding bearings, the application of sliding bearings is very extensive, Slide Bearings generally he is applied at low speed in the working conditions. So the sliding bearing can not replace the role of rolling bearings.

Because the working condition of sliding bearing is in the case of low speed load, therefore, the manufacture of sliding bearing materials to high-strength, high hardness, wear and other materials, are generally used bearing alloy, wear-resistant cast iron, copper-based and aluminum alloy, Slide Bearings powder metallurgy materials, plastics, rubber, hardwood and carbon, Teflon and other materials made.

Sliding bearings in the work of friction is sliding, so the size of the friction depends on the accuracy of the manufacture and manufacture of sliding surface materials. In order to reduce the friction coefficient of sliding bearing, it is usually put on a quantitative lubricant in the working face before the sliding bearing.

Because the sliding bearing is surface contact, so contact surface to maintain a certain oil film, not the whole ring oil groove in the middle of the bearing, Slide Bearings refueling holes do not have to be blocked, to prevent the sharp edges and edges of the oil film broken.

Sliding bearings are often used in mechanical assembly, repair process will often meet the sliding bearing demolition, cleaning, assembly work.

Plain bearings are usually said to be plain, with a simple form, large contact area, if the lubrication remains good, anti-wear performance will be very good, bearing life will be very long. The bearing capacity of sliding bearing is large, Slide Bearings the rotary precision is high, and the lubricating film has an impact-resisting effect. So it has been widely used in engineering.

Sliding bearings are classified in three ways:

Sliding bearing according to the direction of bearing load can be divided into: thrust sliding bearings and radial bearings

According to the lubrication film formation principle is divided into: dynamic pressure sliding bearing and hydrostatic bearing

According to the structure of different types can be divided into: integral sliding bearing split
