FAG spherical roller bearing is mainly used to bear the axial load, but radial displacement of the axis can not be restricted, due to the use of rolling roller, so it is much greater than the ability of thrust ball bearings to withstand the axial load, generally is separable bearings, can be installed tight circle. live ring, shaft and casing installation is not allowed to tilt axis.
39000 Thrust Spherical Roller Bearings
Because this type of INA rolling bearings spherical roller asymmetric, within or roll the outer ring raceway surface, so you can adjust the heart. The axial load capacity, can withstand a certain amount of radial load, more than 69,000 types of load bearing capacity, is the development direction. This kind of bearing can withstand axial load.
69000 Thrust Spherical Roller Bearings
The performance of the same kind of NSK Bearings 39000-type, but the rolling of symmetrical spherical roller, the structure behind the load bearing capacity than 39,000 small, not suitable for development, the new host should be designed to try to use 39000-type bearings.
