A bearing sealing ring, the special structure sealing ring is suitable for deep groove ball bearings, especially for sealing under high temperature conditions, and is integrally formed by a rubber sealing body and a skeleton, the rubber sealing body and the bearing inner ring One or more air slots are opened on the mating end faces. During operation, the heat generated by the bearing after the operation of the bearing, when the pressure in the chamber rises, the expanded gas will leak through the air groove on the inner lip of the sealing ring and leak out of the bearing cavity, thereby reducing the pressure in the bearing cavity. The sealing ring is not ejected, so that the bearing can work normally and safely at high temperature, which not only prolongs the service life of the bearing, but also protects its supporting facilities from damage.
Introduction to high temperature bearings
High temperature resistant bearings are bearings that are resistant to high temperatures. There are many kinds of high temperature resistant bearings. Different types of bearings can be installed according to different needs and different environments.
What is a high temperature bearing
As the name suggests, the materials used in the bearing are: engineering high temperature materials, bearing inner ring, bearing outer ring, bearing rolling element, cage, and sealing ring are all engineering high temperature materials. (When the temperature exceeds 500 degrees, the full ball structure is mostly)
High temperature bearing material classification
ET grade 200℃ high temperature bearing, D(S)T grade 300℃ high temperature bearing, I(X)T grade 400℃ high temperature bearing, W(F)T grade 500℃ high temperature bearing, CT grade 600℃ high temperature bearing, QT grade 700 ℃ high temperature bearing, BT grade 800 ℃ high temperature bearing, C grade 800 ℃ ~ 1400 ℃ high temperature bearing
