How is the slewing bearing sealed at high temperature?

Slewing bearing is an important part of mechanical equipment, which is not only used in engineering machinery, but also widely used in port, military, wharf and other fields.But now many friends are asking about the slewing bearing at high temperature if the bearing is sealed.Here, FRB BEARINGS are simple to talk about.

The slewing bearing is mainly composed of upper ring, lower ring and a full complement ball.These two single row and double row designs, as well as the convenience of pre-drilled mounting holes.In real life, some bearings are only tightened at the fixed blade end, some are tightened at both the fixed blade end and the moving blade end, the way of tightening is cylinder type, there are also institutional linkage.Under the working environment of heavy load and low speed, the bearing is sealed by rubber sealing ring or labyrinth seal.


How is the slewing bearing sealed at high temperature?

The rubber sealing ring seal itself has been widely used due to its simple structure, small space occupied and reliable sealing performance. However, the disadvantage is that the rubber sealing lip is easy to die early and lose sealing performance under high temperature.Therefore, in the high temperature state, the slewing bearing seal had better use labyrinth seal.Swing bearings is a representative rolling bearing, widely used for high speed even very high speed operation, very durable.This kind of bearing has low friction, high speed limit, simple structure, low cost and high precision.

The slewing bearing has a high demand for sealing. When using the slewing ring, we should pay attention to the use, reduce the pollution to the whole bearing in use, and bring the influence to the future use.And when using bearing, should do well maintain maintain work, only so, can lengthen the service life of bearing, let bearing exert the maximum effect in the work.
