High temperature bearing classification

The high temperature resistant bearings are divided into: structural high temperature resistant bearings and special structural high temperature resistant bearings.

First, ordinary structure high temperature bearing

Ordinary structure high temperature resistant bearings mainly refer to bearings designed according to common bearing structure, using high temperature resistant materials, such as high temperature bearing steel, mainly high temperature self-aligning ball bearings, high temperature resistant deep groove ball bearings.

1. High-temperature self-aligning ball bearing: between the inner ring of the two raceways and the outer ring of the spherical raceway, equipped with two rows of steel balls guided by the retainer; the self-aligning ball bearing can withstand large radial loads At the same time, it can withstand a certain axial load; it can be used in a temperature environment of -40 to +300 °C, and is usually not suitable for high-speed operation, but can be operated for a long time at a speed of 100 rpm.

2, high temperature deep groove ball bearing: there is no retainer inside, only the rolling body composition; can meet the working conditions of about 300 °C, usually not suitable for high-speed operation, is a high-temperature low-speed bearing, can be long-term at 200 rev / min run.

Second, special structure high temperature bearing

The special structure high temperature resistant bearing not only uses high temperature resistant materials, but also automatically compensates for the play under high temperature environment, such as spiral spring bearings.

The above is the classification of high temperature bearing, we have a certain understanding of the bearing tough guy, it is also worthy of this reputation. The characteristics of high temperature resistance seem ordinary, but there is a lot of room for development. It can hold up a day in the bearing. Are you saying that? Regarding the classification of high temperature bearings, if there are any deficiencies, I hope to forgive me.
