1. Angular contact ball bearings
There is a contact angle between the ferrule and the ball. The standard contact angles are 15°, 30° and 40°. The larger the contact angle, the greater the axial load capacity. The smaller the contact angle, the more conducive to high-speed rotation. Single-row bearings can Bear radial load and unidirectional axial load. Structurally, two single-row angular contact ball bearings combined on the back share the inner ring and outer ring and can bear radial load and bidirectional axial load.

The main purpose:
Single row: machine tool spindle, high-frequency motor, gas turbine, centrifugal separator, small car front wheel, differential pinion shaft.
Double row: oil pumps, Roots blowers, air compressors, various transmissions, fuel injection pumps, printing machinery.

2. Aligning ball bearings
Double rows of steel balls, the outer ring raceway is an inner spherical type, so it can automatically adjust the shaft center misalignment caused by deflection or non-concentricity of the shaft or housing. The tapered bore bearing can be easily installed on the shaft by using fasteners. Mainly Bear radial load.
Aligning ball bearings

Main uses: woodworking machinery, textile machinery drive shafts, vertical seated self-aligning bearings.

3. Spherical roller bearings
This type of bearing is equipped with spherical rollers between the spherical raceway outer ring and the double raceway inner ring. According to the different internal structures, it is divided into four types: R, RH, RHA and SR. Since the arc center of the outer ring raceway is The bearing center is consistent and has self-aligning performance, so it can automatically adjust the shaft center misalignment caused by deflection or non-concentricity of the shaft or housing, and can withstand radial loads and bidirectional axial loads.
Spherical roller bearing

Main uses: papermaking machinery, reduction gears, railway vehicle axles, rolling mill gearbox seats, rolling mill rollers, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, vertical seated spherical bearings .

4. Thrust spherical roller bearings
The spherical rollers in this type of bearing are arranged obliquely. Since the raceway surface of the seat ring is spherical and has self-aligning properties, it can allow the shaft to tilt to some extent. The axial load capacity is very large. It can withstand several axial loads at the same time. Radial load, oil lubrication is generally used when in use.

Main uses: hydraulic generators, vertical motors, propeller shafts for ships, reducers for rolling screws in rolling mills, tower cranes, coal mills, extruders, and forming machines.

5. Tapered roller bearings
This type of bearing is equipped with truncated cone-shaped rollers. The rollers are guided by the large ribs of the inner ring. They are designed so that the apexes of the conical surfaces of the inner ring raceway surface, outer ring raceway surface and roller rolling surface intersect at the center line of the bearing. On point. Single-row bearings can bear radial loads and one-way axial loads, while double-row bearings can bear radial loads and two-way axial loads, and are suitable for bearing heavy loads and impact loads.

Main uses: Automobiles: front wheels, rear wheels, transmissions, differential pinion shafts. Machine tool spindles, construction machinery, large agricultural machinery, railway vehicle gear reduction devices, rolling mill roll necks and reduction devices.
