Why are sliding bearings widely used?

Sliding bearings are used in textile machines, printing presses, automobiles, tobacco machinery, micromotors, motorcycles and agricultural and forestry machinery and so on. Sliding bearings have their own characteristics and advantages.

The application of sliding bearings is very extensive

So, why sliding bearings will be used how widely?

Slide bearings are especially suitable for large loads and sliding speeds.

Sliding bearings are placed between shafts and housing to reduce friction, wear and to facilitate rotary and/or translation motions. Sliding bearings are made with high properties materials (bronze, lead, graphite, iron, PTFE, …) and can be used dry or with grease.

The advantages of sliding bearings

1, sliding bearings can make the machinery to reduce vibration, reduce noise, prevent pollution, improve working conditions.With proper amount of elastoplasticity, the stress can be distributed on a wider contact surface to improve the bearing capacity of the bearing.Plain bearings have good wear resistance, small friction coefficient and long service life.

 

2, the static and dynamic friction coefficient is similar, can eliminate the creep at low speed, so as to ensure the working accuracy of the machine.No oil lubrication or less oil lubrication, suitable for refueling or difficult to refueling places, can be used without maintenance or less maintenance.

 

3, sliding bearing in the process of operation can form a transfer film, play a role in protecting the grinding shaft, no shaft bite phenomenon.Sliding bearings have low hardness requirements for grinding shafts, and shafts without tempering and tempering can be used, thus reducing the processing difficulty of relevant parts.

 

4, thin wall structure, light weight, can reduce the mechanical volume.The back of steel can be electroplated with a variety of metals and can be used in corrosive media. Sliding bearings have been widely used in sliding parts of various machines.
