Angular Contact Ball Bearing, Kg045aro, Ball Bearing, Motor

Angular contact ball bearings:

Contact Angle between ring and ball, standard of contact Angle is 15 ° , 30 ° , and 40 °
The larger the contact Angle is, the larger axial load capacity will be.
The smaller the contact Angle is, the more conducive the high-speed rotation will be.
Single-row bearing can withstand radial load and one-way axial load.
DB combination, DF combination, and double-row bearings can withstand radial load and two-way axial load.
DT combination is suitable for occasion, like one-way axial load is greater, and the lack of rated load for a single bearing.
High speed with ACH type bearings are mostly used for machine tool spindle, of which the ball diameter is small and numerous.
Angular contact ball bearings are suitable for high speed and high precision rotation.

Main Use:
Single-row: Machine tool spindle, high frequency motor, gas 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
