What are the methods to remove the bearing inner and outer rings?

slewing ring bearings

Anyone familiar with slewing bearing knows that it is composed of four parts, including inner ring, outer ring, rolling body and separator.It can bear axial force and radial force at the same time.It is widely used in heavy equipment such as lifting transport machinery, extractors and construction machinery.So, when we want to take out the bearing inner and outer rings what are the methods?Today, let me give you a brief introduction.

The method to remove the bearing inner and outer ring is as follows:
1. Steel ball method:
3 or 4 steel ball in the damaged bearing rolling body and inner ring shall be distributed evenly inside the bearing outer ring. From the other end of the half axle sleeve pipe, iron bar slightly larger than the bearing inner diameter shall be used to tighten the bearing inner diameter, and it can be struck with hammer.

2. Tire method:
Restore the prototype bearing according to the steel ball method, and screw the half axle nut after the compound tire is installed, but don't screw it too tight.Shake the tire with a sledgehammer on both sides, or hold the tire with your arms open.

3. Half-shaft method:
The two steel ball damaged bearing roll body together with the inner ring on the half shaft are symmetrically distributed inside the bearing outer ring.

4. Self-made puller method:
According to the bearing outer ring diameter, the original prototype is completed according to the semi-axle method. Cut off half of the abandoned cylinder sleeve of 175, 180 or 185, and then the circular hole steel plate of the semi-axle is just exposed on the cylinder liner.

5. Iron plate horizontal and vertical method:
Place the iron plate with a length of 50 cm, a width of 3 cm and a thickness of 1 cm inside the bearing outer ring.

6. Oblique striking method of iron bar:
The iron bar is tilted into the groove of the outer ring of the bearing from the other end, and it is struck with hammer to change the groove position of the bearing outer ring from time to time.

The above is about the rotary bearing take out the bearing inner and outer ring several common methods.If you have any other questions, you can come to FRB Bearings consulting, our company all the staff look forward to your visit.
