1.According to the material is divided into two categories: T type high temperature bearing steel, TP type high temperature bearing steel (ring) ceramic (ball) quality. According to the degree of high temperature resistance, there are seven kinds of high temperature bearing steels: 2 # resistant to 200, 3 # resistant to 300, 4 # resistant to 400, 5 # resistant to 500, 6 # resistant to 600, 7 # resistant to 700,78# resistant to 800

2.High-temperature rolling bearing according to the use of high-temperature bearing steel high-temperature limit degree has seven grades: 200 E, 300 S, 400 X, 500 F, 600 C, 700 Q, 800 B, grade code name first placed in the bearing type, such as 600 C CT6208. The temperature grade corresponds to the high temperature bearing steel number which can withstand its temperature. When the bearing reaches this temperature, the metallographic structure and its hardness still conform to its excellent material standard, and reach or exceed the normal bearing rated load, rotational speed, life and so on. At normal temperature, the high temperature bearing with excellent material life.

3.The main structure is:

1).With the national standard rolling bearings 1, 2, 3, 5, 6, 7, N, U and other eight categories and their diameter series, variants, finished products and their parts shape and size tolerances, shape and position accuracy, rotation accuracy and other quality consistent with the national standard bearings; therefore, high-temperature rolling bearings in accordance with the national standard classification and size specifications code 00000, such as 61816;

2).Low speed <100 revolution/min: There are two kinds of full rollers without cage, namely, T00000 and T00000B without ball-loading notch, the rollers are full of raceways, bearing 1.4 times, and can not add lubricants because of small friction and wear.

3).High school speed > 100 R / min: TS00000 with cage.

4).Lubrication: Grade S adds 300 C S high temperature grease with code Y, and Grade X adds 400 C X high temperature grease with code Z to reduce friction. In addition to installing double-sided (code - 2Z) dustproof cover, Grade C and Grade B adds high temperature lubricant by users themselves.

5).Class 5.6 variants: Class S single-sided (code-Z) or double-sided (code-2Z) 300 6550 (rubber cover) can prevent high temperature grease from overflowing.

6).Interlaced type, that is, by different temperature levels of parts, grease and other matching, to achieve a specific performance. The high temperature grade code is based on the high temperature rating of the ring.

For example, (P represents ceramic balls):

1 types of high temperature aligning ball bearings T10000 and TS10000; type TP10000 and TSP10000.

2 types of high temperature self-aligning roller bearing TS20000

3 types of high temperature tapered roller bearings TS30000

7 types of high temperature angular contact ball bearings T70000 and TS70000; type TP70000 and TSP70000.

Type N high temperature cylindrical roller bearings TN0000 and TSN0000

U-type high-temperature external spherical ball bearings TU0000, TU0000C, TSU0000; TPU0000, TPU0000C, TSPU0000, can be allocated to a variety of bearing seats

Compared with ordinary bearings, High temperature bearing has the corresponding material resistance to high temperature 200~800℃, hardness HRC60 above, greater bearing capacity, high hardness and wear resistance, strong impact and bite resistance, smooth and lustrous appearance, low speed T00000, T00000B type can not use lubricants, and T00000C type has self-lubrication. Applicable to aerospace, armaments, weapons, vehicles, painting, baking, heat engine, ceramics, carbon, sponge iron, plastics, cement, brick, glass, refractories, lamps and lanterns, drying, vacuum, metallurgy, chemical and metal heat treatment and other high-temperature operation or spontaneous high-temperature mechanical equipment.
