Push method
Push the bearing using a press, smooth and reliable, does not damage the machine and bearing shielded room. Presses pushed manually, mechanical or hydraulic presses is pressed.
Attention to matters: press focus should be on the center of the shaft shall not pressure bias.
Percussion method
Striking force is generally applied to the bearing inner ring, the shielded room striking force should not be applied to the bearing rolling elements and the retainer, this method is simple, but easily damage the bearings, when the bearings are located on the end of the shaft, with less than bearing diameter brass or other soft metal material up against the shaft end bearing lower part and pad, hammer gently tap to remove by hand. This method should pay attention to pad placement location should be appropriate, the focus should be correct.
Pull out the method
Special puller, demolished, as long as the rotation of the handle, the bearing will slowly pull out. Remove the bearing outer ring, the feet angled puller should open outward; removing the bearing inner ring, feet should puller card end face of the bearing inner ring.
Pay attention to matters:
1, should the inner ring of the the retractors hooked bearing puller, and should not hook on the outer ring to avoid bearing loose over or damaged;
2, the use of the puller, to make the screw aligned in the center of the shaft hole, not skewed. Should also focus on the retractors and bearing force retractors and bearing damage;
Focus on prevent retractor slipping;
4 corner puller feet less than 90 °.
Hot-split method
Used to disassemble the tight fit of the bearing. First heated to about 100 ℃ oil pouring used oil can be demolished bearing to be bearing ring thermal expansion, you can use the puller bearing puller.
