* Rings and balls, the contact angle between the standard contact angle of 15 °, 30 ° and 40 °
* The contact angle the greater the greater the axial load capacity
* The smaller the co ntact angle is more conducive to high-speed rotation.bearings high speed
* Single row bearings can bear radial load and axial load
* DB combinations, DF combinations and double-row bearings can bear radial load and axial load
* DT combined application of axial load, single bearing rated load occasion
* High speed using the ACH-type bearings, ball diameter, ball number, mostly used for machine tool spindle.roller thrust bearings
* The angular contact ball bearings for high-speed and high-precision rotation
* The structure is on the back of the combination of two single row angular contact ball bearing inner and outer rings, radial load and axial load
* No filling slot bearings sealed type.tool bearings
Mainly applied to the cage:
* Steel stamping cage (Bowl ... single row; S-shaped, crown-shaped double row.)
* The copper alloy or phenolic resin cutting cage, synthetic resin forming Cage

Main purposes:
* Single row: machine tool spindles, high frequency motors, gas turbines, centrifuges, small front wheel, the differential pinion shaft
Double row: oil pump, Roots blower., Air compressors, various types of transmission, fuel injection pump, printing machinery

Four point contact ball bearings
Can withstand the radial load and axial load
* A single bearing can replace the positive combination or the back of the combination of angular contact ball bearings
* Applies under pure axial load or axial load component of a larger synthetic load
* This class bearing axial load in any direction can form a contact angle (α), rings and balls, the total * duplicity point of contact with any of the contact line

Mainly applied to the cage:
Copper alloy cutting cage

Main purposes:
Aircraft jet engines, gas turbine
