Bearing characteristics


1.General-purpose bearings
The universal matched bearings are specially processed. When the bearings are installed close to each other, any combination can achieve the established internal clearance or pre-tensioning and average load distribution without the use of gaskets or similar devices.
Paired bearings are used: when the load bearing capacity of a single bearing is insufficient (using the channeling configuration) or when the combined load or an axial load acting in both directions is used (using the back-to-back or face-to-face configuration).
2, the basic design of the bearing (can not be used as a general matching), for the configuration of a single bearing
Single row angular contact ball bearings of basic design are mainly used in configurations where there is only one bearing at each position. Its width and protrusion are ordinary tolerances. Therefore, it is not suitable to install two single-row angular contact ball bearings next to each other.
Accuracy class
Angular contact ball bearing accuracy grades include dimensional tolerances and rotational accuracy. The accuracy is expressed as P0 (normal), P6 (P6X), P5, P4, P2 from low to high. In addition, European and American brands also use P3, P7, and P9 to indicate the accuracy level. P3 is equivalent to the P6 level of the ISO and JIS standards, P7 is equivalent to the P4 level, and P9 is equivalent to the P2 level.
Types of
Angular contact ball bearings are: 7000C (∝ = 15 °), 7000AC (∝ = 25 °) and 7000B (∝ = 40 °). The lock of this kind of bearing is on the outer ring. Generally, the inner and outer rings cannot be separated, and can bear the combined load of radial and axial directions and the axial load of one direction. The ability to withstand axial loads is determined by the contact angle. The larger the contact angle, the higher the ability to withstand axial loads. This type of bearing can limit the axial displacement of the shaft or housing in one direction.
The contact ball bearing has a higher limit speed and can support both radial and axial loads, as well as pure axial loads. Its axial load capacity is determined by the contact angle and increases with the increase of the contact angle.
