QJ7308-double cage

Features:
1.There is a contact angle between the ring and the ball, the standard contact angle is 15 °, 30 ° and 40 °;
2.The greater the contact angle, the greater the axial load capacity;
3.The smaller the contact angle is more conducive to high-speed rotation;
4.Single row bearings can withstand radial load and unidirectional axial load;
5.DB combination, DF combination and double row bearing can withstand radial load and bidirectional axial load;
6.DT combination for a single one-way axial load larger, a single bearing rated load of the occasion;
7.High-speed ACH-type bearings with small ball, the number of balls, mostly for machine tool spindle;
8.Angular contact ball bearings for high-speed and high-precision rotation;
9.Structure for the back of the combination of two single row angular contact ball bearings shared inner and outer ring, can withstand radial load and two-way axial load;
10.No trough bearing also has a sealed type.

Mainly applicable cage:
Steel plate stamping cage (bowl ... single row; S shaped, crown ... double row), copper alloy or phenolic resin cutting cage, synthetic resin forming cage.

The main purpose:
Single row: machine tool spindle, high frequency motor, steam turbine, centrifugal separator, small car front wheel, differential pinion shaft.
Double row: oil pump, Roots blower, air compressor, all kinds of transmission, fuel injection pump, printing machinery.
