Product Description
22319 EKJA/VA405 Vibrating Screen Bearings 22319EKJA/VA405 Spherical Roller Bearings
Bearings in Vibrating Screens 22319EKJA/VA405:
Vibrating screens are used for grading (i.e. separation of solid materials by grain size) of materials and other vibratory machinery such as road rollers and saw frames are among the machines subjected to the most severe stresses.
The rolling bearings in the exciter units of these machines must support not only high loads and high speeds but also accelerations and centrifugal forces. Many of these applications involve adverse environmental conditions such as contamination and moisture.

Vibrating Screen Bearings 22319EKJA/VA405 Bearing:
Bearing performance requirements 22319EKJA/VA405 :
Vibrating screens place unique demands on the bearings used in them. Therefore, the bearings designed for such applications have to be able to withstand extreme operating conditions such as high speed, loads, accelerations and temperatures.
The important features of a Vibrating Screen Application are as listed below 22319EKJA/VA405 :
1. Rotating Outer Ring Load : In most of the screens, it is the outer ring that rotates and not the inner ring. Hence the outer ring must be fitted in the housing with interference fit.
2. Heavy Load : The relatively high load of this application demands a high capacity bearing – usually a Spherical Roller Bearing.
3. Misalignment : Most screens use a single long shaft supported by two bearings. In such machines, shaft bending and consequently, misalignment is likely to occur. Thus, Spherical Roller Bearings are usually preferred for use in these applications.
4. Axial Movement of Shaft due to Thermal Expansion : Most of the Vibrating Screens run hot due to heavy load and speed, as well as the friction in the Sealing arrangement. At times, heat is also transmitted from the process material, which itself is hot. This build up of heat causes the shaft to expand with respect to the housing, when hot, and to contract, when cold. Spherical Roller Bearings are, therefore, fitted on the shaft with a loose fit between the inner ring and the shaft in order to facilitate such movements.
5. High Speed : Typical operating speeds of a Vibrating Screen vary between 800 to 1200 rpm.
6. High Acceleration : Due to reciprocating motion of the vibratory application, bearings are subjected to high "g" or acceleration. Normal cages cannot withstand such accelerations. Hence enhanced cage design needs to be used in such applications.
7. High Temperature : The combination of heavy load, high speed and the Seal friction lead to a very high level of heat generation. The bearings, therefore, must be capable of withstanding high temperatures for a considerable period of time, without any loss of performance.
8.Contaminated Operating Environment : The environment, in which the vibratory screens are required to operate, is highly contaminated most of the time. While external seals are used in order to minimise ingress of abrasive foreign particles, infiltration by some amount of such particles is practically unavoidable. The bearings, therefore,should be capable of tolerating presence of a certain amount of such particles.
3. Misalignment : Most screens use a single long shaft supported by two bearings. In such machines, shaft bending and consequently, misalignment is likely to occur. Thus, Spherical Roller Bearings are usually preferred for use in these applications.
