Disassembly and installation of screw locking ball insert bearings

987 Published by admin Aug 14,2018

The screw locking ball insert bearings is actually a variant of the deep groove ball bearing, which is characterized in that the outer diameter outer surface of the outer ring ball is spherical, and can be fitted into the corresponding concave spherical surface of the bearing seat to serve as a centering function. The outer spherical bearing is mainly used to bear the radial and axial combined load mainly based on the radial load, and generally it is not suitable to bear the axial load alone.

Disassembly of screw locking ball insert bearings
1. First loosen the locking screw on the eccentric sleeve of the bearing with an Allen key, then insert the small iron rod into the counterbore on the eccentric sleeve of the top cover and loosen the eccentric sleeve against the direction of rotation of the shaft.
2. Loosen the bolts that secure the housing. Remove the bearing from the shaft together with the housing. Note before the housing on one end of the shaft is removed. The bearing bolts at the other end of the shaft should be loosened to prevent the bearings at both ends from being damaged by each other.

Installation of screw locking ball insert bearings
1. Before installing the screw locking ball insert bearings on the shaft, the bearing pin of the bearing sleeve must be unplugged, and the surface of the journal should be smoothed and cleaned, and the oil should be rust-proof and lubricated at the journal (allowing the bearing to rotate slightly on the shaft).
2. Apply lubricant to the bearing seat and bearing mating surface, and install the bearing into the bearing housing. Then the assembled bearing is placed on the shaft together with the bearing housing. Push to the desired location for installation.

3. The bolts of the fixed bearing housing should not be tightened first, so that the bearing housing can rotate in the bearing housing. Also install the other end bearing and seat on the same shaft, turn the shaft a few turns, and let the bearing itself automatically find the position. Then tighten the bearing block bolts.
4. Install the eccentric sleeve. First, eccentric sleeve is placed on the eccentric step of the inner sleeve of the bearing, and the shaft is tightened by hand in the direction of rotation. Then insert or hold the small iron rod against the counterbore on the eccentric sleeve. 1. Use the hammer to strike the small iron rod in the direction of rotation of the shaft. Install the eccentric sleeve securely and finally lock the socket head cap screws on the eccentric sleeve.
