About Angular Contact Ball Bearing

About Angular Contact Ball Bearing

1. There is a contact angle between the ring and the ball, and the standard contact angles are 15,30 and 40;

2. The larger the contact Angle, the greater the axial load capacity;

3. The smaller the contact Angle, the more conducive to high-speed rotation;

4. Single-column bearing can withstand radial load and one-way axial load;

5. DB combination, DF combination and double-column bearing can withstand radial load and two-way axial load;

6. The DT group is suitable for a large one-way axial load, and the rated load of a single bearing is lacking;

7. High-speed ACH bearings have small ball diameter and many balls, which are mostly used for machine tool spindle;

8. Angle contact ball bearings are suitable for high-speed and high-precision rotation;

9. The two single-column angle contact ball bearings with reverse combination share the inner and outer rings, which can withstand radial load and two-way axial load;

10. No loading tank bearing also has a sealing type.

Main applicable maintenance frame:

Steel plate stamping holder... single column; S shape, crown... double column, copper alloy or phenolic resin cutting holder, synthetic resin forming holder.

main application:

Single column: machine tool spindle, high-frequency motor, combustion steam turbine, centrifugal separator, front wheel of small car, differential pinion shaft.

Double column: oil pump, Roots blower, air tightening machine, all kinds of transmission, fuel injection pump, printing machinery.
