Thrust bearings are four points following a corner bearing, double row (single) bearing a corner angle, two-way thrust tapered and cylindrical roller bearings, has recently developed a braking force to the bearing roller bearing.
Four-point bearing a corner, double (single) row angular contact ball bearings for thrust bearings are not allowed to bear the radial load bearing bore and therefore the corresponding parts in the assembly of these bearings, the bearing outside diameter must be greater than large diameter about 0.5 mm. Or roller bearing bore diameter less than about 0.5 mm.
for the four-point contact ball bearings, install the same type of separation will not be interchangeable ring, changing the factory to prevent the axial clearance.
Thrust tapered roller or thrust cylindrical roller bearings in every circle, the same type of bearings do not exchange, change the factory to prevent the axial clearance.
The end thrust bearing inner ring must be pressed install and axial to lock. To prevent relative rotation in the roll neck, roll neck with the surface caused by wear and tear, burn.
Brake roller bearing axial force when used by two axial bearing boxes to locate and adjust the axial clearance. When installing the bearing box, make sure that the bearing inner ring and main bearings inside and outside the ring snapping. When both sides of the rack axially fixed bearing box, should be taken to remove both sides of the bearing housing to the rack into the process will produce the bearing housing to the shaft direction of axial movement.
