Bearing centering performance speed operation
When the center line of the shaft is inclined relative to Bearing the center line of the bearing seat hole, the bearing can still work normally. Double row radial spherical ball bearings and double row radial spherical bearings have good centering performance. The working speed of the bearing shall be lower than the limit speed. The limit speed can be increased by selecting high-precision bearings, improving cage structure and materials, adopting oil mist lubrication and improving cooling conditions.
Lubrication performance
The lubrication purpose of the bearing is to reduce the internal friction and wear of the bearing and prevent burning and sticking; Extend its service life; Discharge friction heat and cooling to prevent bearing overheating and lubricating oil aging; It also has the effect of preventing foreign matters from invading the interior of the bearing, or preventing rust and corrosion.
Wear resistance
When the bearing works, not only rolling friction but also sliding friction will occur between the ring, rolling element and cage, so that the bearing parts are constantly worn. In order to reduce the wear of bearing parts, maintain the accuracy and stability of the bearing and prolong Bearing the service life, the bearing should have good wear resistance.
