Single Row Angular Contact Ball Bearing

Single row angular contact ball bearing can only withstand one direction of the axial load. The rolling body load line and radial load line is not in the same radial plane generating an internal axial force, so the product must be installed in pairs. Its structure can be divided into separation type, non-separation type and paired configuration.

The outer ring, inner ring, cage and ball component of separation type of single row angular contact ball bearing can be installed respectively due to its outer ring raceway without fore shaft. These are mainly miniature bearings with less than 10 mm bore size and widely used in the gyro rotor and micro motors and other devices which have higher requirements of dynamic balance, noise, vibration and stability.

The ring groove of non-separation angular contact ball bearing is locked, so the two sets of ring can not be separated. Non-separation type has three kinds of contact angle. It is applicable to bear larger axial load when its contact angle is 40°while it is mainly used in precision spindle bearings if its contact angle is 25°. Also, if it has 15° contact angle, the product is suitable for larger precision bearings.

Paired configuration angular contact ball bearing can bear radial and axial load, and it can also be subjected to pure radial load and axial load in either direction. When the bearing is installed on the machine after fastening, it completely eliminates the bearing clearance and makes the ring and ball in the pre-tightening state, thereby enhancing its rigidity of combination bearing. The product has three different configuration types which are back-to-back arrangement, face-to-face arrangement and tandem arrangement.

The back-to-back arrangement single row angular contact ball bearing with DB postposition code, such as 7000/DB, has good rigidity, good overturning torque performance and can bear axial load in two directions while the face-to-face arrangement product with DF postposition code, such as 7000/DF, is not as good as the back-to-back arrangement product. It can also bear axial load in two directions. In terms of the tandem arrangement product with DT with postposition code, such as 7000/DT, it can connect three or more bearings at the same support, but it can only bear single direction axial load. Generally, in order to balance and limit the axial displacement of the shaft, another support need to install bearings which can withstand another direction axial load

We are a specialized single row angular contact ball bearing manufacturer based in China. We provide various types of products such as open deep groove ball bearing, four row taper roller bearing, and brass cage spherical roller bearing.
