Do you know the categories and materials of high temperature ball bearing?

high temperature ball bearing is a kind of tolerance for high temperature of bearing. There are many kinds of, high-temperature bearing, according to the different needs of different environment can install different types of bearings. High temperature resistant bearing is widely used in metallurgy, mill furnace, glass, paint spraying equipment or blast furnace burden and other high temperature operating machinery.The use of the bearing temperature higher than 130 degrees must choose high temperature bearing, because ordinary bearing the high temperature of maximum temperature is 130 degrees, such as ordinary bearing temperature above 130 degrees can cause the damage of the bearing and equipment, and the use of high temperature ball bearing is 150-500 degrees, so when the bearing of choose and buy, must take into account the use of the bearing temperature and the environment.

high temperature ball bearing from structural process can be divided into: common structural resistance to high temperature bearing resistance to high temperature and special structure bearing.Ordinary structure: high temperature resistant bearing mainly refers to is in accordance with the commonly used bearing structure, using high temperature resistant materials such as resistance to high temperature bearing steel, design of the bearing, mainly has high temperature resistant self-aligning ball bearing, such as resistance to high temperature deep groove ball bearing.High temperature resistant self-aligning ball bearing. High temperature: self-aligning ball bearing in two race between inner ring and groove for spherical outer ring, equipped with guided by retainer two columns of steel ball. Self-aligning ball bearing can bear radial load, at the same time also can absorb a certain amount of axial load.Bearing with stamping steel cage, high temperature lubricating grease with high quality white, can be used for 40 to + 300 ℃ temperature environment, can meet the working conditions within 300 ℃.Bearings are often production, according to the common tolerance and clearance, than the ordinary bearing so often is not suitable for high-speed operation. But usually can be long running in the speed of 100 r/min.

Resistance to high temperature ball bearing Internal for high temperature deep groove ball bearing, no retainer, only rolling body composition; Around 300 ℃ can meet the working conditions, according to the common tolerance in production, and the clearance is greater than the ordinary bearing, so usually are not suitable for high-speed operation situation, belong to high temperature and low speed bearings, usually within 200 RPM speed run for a long time.High temperature resistant special typeSpecial high temperature resistant bearing structure, not only material with high temperature resistant materials, more from the structure to realize automatic clearance under the environment of high temperature compensation, such as spiral spring bearing.
