Angular contact ball bearings
* there was contact between the ring and ball angle, standard contact angle is 15 degree, 30 degree and 40 degree
* contact angle the greater the greater the axial load capacity
* contact angle is increased with high speed rotation
* row bearings can bear radial load and axial load
* DB combination, DF combination and double row bearings can bear radial load and axial load bidirectional
* DT combination of suitable axial load is large, insufficient rated load single bearing occasion
* high speed with ACH type bearing ball diameter, ball number of small, mostly used for the machine tool spindle
* angular contact ball bearings are suitable for high speed and high precision rotation
* two single row structure for back combination of angular contact ball bearing sharing of inner ring and outer ring, can bear radial load and axial load bidirectional
* no filling slot bearing has sealed
The holder is mainly suitable for the:
* steel stamping cage (bowl... Single S shaped, crown shaped... Dual)
* copper alloy or phenolic resin cutting holder, synthetic resin molded retainer
The main purposes:
* row: machine tool spindle, high frequency motor, gas turbine, centrifugal separator, the small car front wheel, differential pinion shaft
* double: pump, roots blower, air compressor, various types of transmission, fuel injection pump, printing machinery
Four point contact ball bearing
* can bear radial load and axial load bidirectional
* angular contact ball bearing a single bearing can replace the front or back of the combination of portfolio
* applicable to bear pure axial load or axial load component synthesis of large load
* a contact can form which this kind of bearing axial load in any direction are the angle (alpha), so the ring and ball * in either the contact line play a double game point contact
The holder is mainly suitable for the:
Copper alloy cutting holder
The main purposes:
Aircraft jet engine, gas turbine
