Do you know the disassembly and installation of ball insert bearings?

Outer spherical bearings are mainly suitable for occasions requiring simple equipment and parts, and are often used in agricultural machinery, transportation systems or construction machinery. Deep groove ball bearings are the most common type of rolling bearings. The basic deep groove ball bearing is composed of an outer ring, an inner ring, a group of steel balls and a group of retaining frames.

Disassembly of ball insert bearings:

1. First use a wrench to loosen the locking screw on the bearing eccentric sleeve, then use a small iron rod to insert the counterbore on the eccentric sleeve of the top cover, and loosen the eccentric sleeve against the rotation direction of the shaft.

2. Loosen the bolts holding the ball insert bearings housing. Remove the bearing together with the bearing seat from the shaft. Note before removing the bearing housing at one end of the shaft. The bearing seat bolts at the other end of the shaft should be loosened to prevent the bearings at both ends from being stiff and damaged.

Installation of ball insert bearings:

1. Before installing the bearing on the shaft, the fixing pin of the bearing jacket must be removed, and the surface of the journal should be polished smooth and clean, and the journal should be coated with oil to prevent rust and lubrication (allowing the bearing to rotate slightly on the shaft).

2. Apply lubricating oil to the mating surfaces of the ball insert bearings housing and bearing, and install the bearing into the bearing housing. Then put the assembled bearing on the shaft together with the bearing seat. Push to the desired location to install.

3. Do not tighten the bolts that secure the bearing housing first, but allow the ball insert bearings housing to rotate in the bearing housing. Also install the other end bearing and seat on the same shaft, rotate the shaft a few times, and let the bearing itself find the correct position automatically. Then tighten the ball insert bearings seat bolts.

4. Install an eccentric sleeve. First put the eccentric sleeve on the eccentric step of the ball insert bearings inner sleeve, and tighten it by hand along the rotation direction of the shaft. Then insert or hold the small iron rod into the countersink hole. Use a hammer to strike the iron rod in the direction of rotation of the shaft. Install the eccentric sleeve firmly, and finally tighten the hexagon socket screws on the eccentric sleeve.
