The definition of angular touch ball bearings
(Angular Contact Ball Bearings) angular contact ball bearing; also known as the radial thrust ball bearing; it allows the operating speed and the vicinity of the deep groove ball bearing; but the support rigidity is stronger than the deep groove ball bearing; the first is because of the bearing It can be loaded with more steel balls; its radial load can be larger than that of general ball bearings; and it can also accept large axial loads or accept pure axial loads. These bearings are generally used in pairs; Small span rigid double support shaft or fine spindle; can improve the rigidity of the bearing system.
Layout characteristics of angular touch ball bearings
Single row angular touch ball bearing

This type of imported bearing; can accept radial load and axial load in one direction. The ball has a touch angle of 15°, 25°, 30° or 40° with the inner ring and outer ring. The larger the touch angle is; the axis The greater the acceptance of the load. In general, the two single-row angular touch ball bearings are opposed; the internal clearance is adjusted and applied.
Paired double bearings

Two radial bearings; combined pairs of imported bearings are called pairs of double bearings. General; pairs of double bearings are composed of the same angular touch ball bearings or the same tapered roller bearings.
Pairs of double-branched species, paired frontal twins (DF-shaped) with positive outer ring, reversed paired twins (DB-shaped) with opposite sides, and side-by-side paired (DT-shaped) in the same direction .
DF-shaped and DB-shaped pairs of double-bearing bearings; capable of accepting radial loads and axial loads in two directions; DT-shaped for applications with large axial loads in one direction.
Double row angular touch ball bearing


The double row angular touch ball bearing is to match the outer ring of the two single row angular touch ball bearings; the inner ring and the outer ring are all integrated. Therefore, the imported bearing of this layout; has two thrust loads Talent.
Detailed classification and type control:
1, a = 15o angular touch ball bearing (70000 C type)
2, a = 25o angular touch ball bearing (70000 AC type)
3, a = 40o angular touch ball bearing (70000 B type)
4, a = 15o high-speed sealing angle touch ball bearing (B70000 C-2RZ type)
5, a = 25o high-speed sealing angle touch ball bearing (B70000 AC-2RZ type)
6. High-speed sealing angle touch ceramic ball bearing with a=15o (B70000 C-2RZ/HQ1 type)
7. High-speed sealing angle touch ceramic ball bearing with a=25o (B70000 AC-2RZ/HQ1 type)
8, back to back paired double-angle touch ball bearing [70000 C (AC, B) / DB type]
9, face-to-face paired double-angle touch ball bearing [70000 C (AC, B) / DF type]
10, series paired double-angle touch ball bearing [70000 C (AC, B) / DT type]
11. Double row angular touch ball bearing with ball gap (0000 type a=30o)
12. Double row angular touch ball bearings without ball gap (0000 A type a=30o)
13. Double row angular touch ball bearing with dust cover on one side (0000 AZ type a=30o)
14. Double row angular touch ball bearings with dust cover on both sides (0000 A-2Z type a=30o)
15. Double row angular touch ball bearing with sealing ring on one side (0000 A-RZ type a=30o)
16. Double row angular touch ball bearing with sealing ring on both sides (0000 A-2RZ type a=30o)
17, four-point touch ball bearing (QJ type a = 35o)
The primary use of angular touch ball bearings <br> Single row angular touch ball bearings: machine tool spindles, high frequency motors, gas turbines, centrifugal separators, small car front wheels, differential pinion shafts.
Double row angular touch ball bearings: oil pump, Roots blower, air compressor, various transmissions, fuel injection pumps, printing machinery

It is produced from quartz sand and high quality anthracite under high temperature in an electric resistance furnace.

By Jet mill machining to crush into different particle size to meet different application requirements.

It can  be used for produce the abrasive tools. It is also fit for process the grind metals and non-metals material of low tensile strength, such as grey cast iron, brass, aluminum, stone, leather and hard rubber etc.

 Also can be used as refractory materials and in electronic industry.
