1. Check that the spacing LH between the housing support and the side of the housing cover is less than the total width LB of the bearing set (measured on the outer ring). If this is not the case, there is axial play in the main shaft. Propose about 100 mm The diameter LH should be 10-15 microns smaller. If the difference between the two is too large, it will cause deformation when tightening the screw.
2. Especially when using large bearings; the main shaft of the spindle is in the standing position when the device is installed.
3. Place the shaft labyrinth seal, can be listed and the bearing seat cover) slightly heated. Remember not to forget the bearing seat cover.
4. Heating the bearing on a heating plate or induction heater, a temperature 20 to 30 degrees Celsius higher than the ambient temperature is generally sufficient to allow the bearing to pass freely through the shaft.
5. Ensure that the bearing is oriented correctly. If using a matched bearing; check the symbol on the outer diameter of the outer ring.
open:
The machined end bearings generally have a small dryness and cooperation on the shaft. The estimated pull-out force (PAN) is 70 times the hole diameter (in N) of the bearing set consisting of three bearings. The spindle used in the example is There are three threaded holes in the shaft head for disassembling the use. These holes and three long screws make it easy to remove the bearing from the shaft; there is no danger of damaging the bearing. At the end of the thread and the seal/space Use bushings between components to prevent damage to the exterior of the components. If the bearings are necessary to push longer intervals; use bushings with different lengths to prevent the screws from being too long. If there are no holes in the shaft head; Clamp the cover with a long puller; a better way is to use a labyrinth seal/pad.
