Vibrating screen bearings (for example 22340 CCJA/W33VA405) are widely used in mine vibrating machinery, vibrating motors, etc. The working conditions of these bearings are very bad. The humidity, revolving speed temperature is high. Moreover, there is strong vibration and shock, which resulting in very large workload.

The vibrating screen bearing has two rows of rollers, one column mainly bears the load on one side, but also can bear the axial load of any column. It has a high radial load capacity, which is more suitable for heavy loads or vibration loads, but it also has limitations, such as being unable to withstand pure axial loads.

The vibrating Inclined Screen is the most popular type of screen. There are various types of Inclined Screens, including two and four bearing, high-speed, and high-frequency screens. The overwhelming majority of …

What are vibrating screens and which are its main applications for use. Also called simply screens, a vibrating screen is formed by a vibrant chassis that supports in its interior one or several surfaces or elements of screening. The screens serve to classify the different particles by size, starting from a bulk product in a continuous process.

The vibration screen bearing has strong bearing capacity, good impact resistance, high reliability, good lubrication performance, and can overcome the deflection and deformation of the shaft.Features of bearings for vibration screen:1. Vibrating screen bearings are generally symmetrical spherical rollers and cylindrical rollers; 2.
