High Precision/Speed Angular Contact Ball Bearing (shaft/axle bearing) 7220AC/Dt

Angular contact ball bearing/shaft bearing/axle bearing/paired bearing

1. Description
Angular contact ball bearings are designed to handle both radial and axial loads simultaneously, making them ideal for high-speed applications. The larger the contact angle, the greater the load capacity. Bearings with high precision and speed typically have a contact angle of 15 degrees. When an axial force is applied, the contact angle increases slightly.

Single-row angular contact ball bearings can only support axial loads from one direction. They may generate additional axial forces when carrying radial loads, limiting movement in one direction. Double-row angular contact ball bearings, when paired, are installed with opposite outer rings, reducing axial forces and allowing bidirectional axial movement control.

2. Structure
7000C type (15°)
7000AC type (25°)
7000B type (40°)

3. Cage
Brass or synthetic resin cages are available.

4. Features
High load capacity
Excellent rigidity
Smooth operation
Long service life
High speed capability
High precision

5. Application
Single-row angular contact ball bearings are used in lathe spindles, high-frequency motors, gas turbines, centrifugal machines, front wheels of small vehicles, and differential gear shafts.
Double-row angular contact ball bearings are commonly found in oil pumps, root blowers, air compressors, gearboxes, fuel injection pumps, and printing machinery.
