Parameter:

In order to meet the performance requirements of bearings, Chinese bearing steel has more excellent performance:
1. Higher contact fatigue strength
2. after heat treatment with higher hardness to meet the bearing performance requirements
3. higher wear resistance, lower friction coefficient
4. Higher elastic limit
5. better impact toughness and fracture toughness
6. better dimensional stability
7. better rust resistance

ANGULAR CONTACT BALL BEARING SERIES

where C is 15 degrees contact Angle, AC is 25 degrees contact Angle, B is 40 degrees contact Angle, the bearing limit speed is higher, can bear both radial load and axial load, can also bear pure axial load, the axial load capacity is determined by the contact Angle, and increases with the increase of the contact Angle. It can only withstand the axial load in one direction, when bearing the radial load, it will cause additional axial force, and must apply the corresponding reverse load, so the bearing is generally used in pairs.


SINGLE ROW ANGULAR CONTACT BALL BEARING

Single-row angular contact ball bearings can only bear axial load in one direction, and additional axial force will be caused when bearing radial load. And only limit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact Angle of 40 degrees, so they can withstand large axial loads. Angular contact ball bearings are of a non-separation design, and the shoulders on both sides of the inner and outer rings are not high or low. In order to increase the load capacity of the bearing, the shoulder on one side is machined lower, so that the bearing can fit more steel balls.

DOUBLE ROW ANGULAR CONTACT BALL BEARING

Double row angular contact ball bearings can bear large radial loads, mainly radial and axial combined loads and torque loads, limiting the axial displacement of both sides of the shaft. The inclinability between the inner and outer rings of the double-row angular contact ball bearing is limited in the parts mainly used to limit the two-way axial displacement of the shaft and the housing. The allowable inclination Angle depends on the internal clearance of the bearing, the bearing size, the internal design and the force and moment acting on the bearing, and the allowable inclination Angle should ensure that no excessive additional stress is generated in the bearing. If the inclination Angle between the inner and outer rings of the bearing exists, the life of the bearing will be affected, and the running accuracy of the bearing will be reduced, and the running noise will be increased. Double row angular contact ball bearings generally use nylon cages or brass solid cages. When installing double row angular contact ball bearings, attention should be paid to the fact that although the bearings can withstand two-way axial loads, if there is a ball loading gap on one side, care should be taken not to let the main axial load pass through the groove side with a gap. When the bearing is used, attention should be paid to making the raceway without the ball filling gap bear the main load.
