Structure and characteristics of angular contact ball bearings

 

Single row angular contact ball bearings with lock in the outer ring (Type 70000C (AC)) and single row angular contact ball bearings with lock in the inner ring (Type 70000B)

General characteristics

1. The bearing capacity is large, and the rated dynamic load ratio is 1~1.4

2. It can bear both radial load and axial load, and can also bear pure axial load, the larger the contact angle, the greater the axial bearing capacity

3. It can only bear the axial load in one direction, and when it bears the radial load, it will cause additional axial force, which is generally used in pairs to balance the axial force

4. High limit speed

Other Features:

70000C

α= 15°

70000AC

α= 25°

70000B

α= 40°

 

Angular Contact Ball Bearings in Pairs (Tandem Arrangement) (70000C (AC,B)/DB type)

 

General characteristics

1. It can bear large unidirectional axial loads, and the bearing capacity increases with the increase of contact angle

2. It can limit the axial displacement of the shaft or shell in one direction

3. In the limit speed

 

Other features: For large axial loads

 

Angular Contact Ball Bearings in Pairs (Back-to-Back) (Type 70000C (AC,B)/DB)

General Characteristics:

1. It can bear two-way axial load, and the bearing capacity increases with the increase of contact angle

2. The axial displacement of the shaft or housing can be limited by preloading

3. The stiffness and rotation accuracy of the bearing can be increased by preloading

4. In the limit speed

Other Features:

It has a large bending rigidity bearing and is suitable for the support of cantilever shafts

 

Angular Contact Ball Bearings Mounted in Pairs (Face to Face Arrangement) (70000C (AC,B)/DF Type)

General characteristics

1. It can bear two-way axial load, and the bearing capacity increases with the increase of contact angle

2. The axial displacement of the shaft or housing can be limited by preloading

3. The stiffness and rotation accuracy of the bearing can be increased by preloading

4. In the limit speed

 

Outer separable angular contact ball bearings and inner separable angular contact ball bearings (SN70000 type)

General characteristics

1. Large carrying capacity

2. It can bear radial and axial combined loads based on radial loads

3. It can limit the unidirectional axial displacement of the shaft and housing

4. High limit speed

Other features: The inner and outer rings can be installed separately, suitable for parts with limited installation conditions, and are generally used in pairs

 

Double Row Angular Contact Ball Bearings (Type 00000)

General Characteristics:

1. Large carrying capacity

2. It can withstand two-way axial load, and can also withstand a certain overturning moment

3. It has the characteristics of back-to-back bearings installed in pairs, but the width is narrow

4. High limit speed

Other characteristics: Contact angle α=30°, good stiffness
