Popularity：Publication time：2025-03-15
How to solve the problems of peeling, burning, cracking and other defects that may occur during the use of bearings? In fact, the common problems of bearing damage can be divided into the following categories: peeling burns, crack defects, cage damage, abrasion and jamming, rust and corrosion, abrasion, electrical corrosion, indentation and collision, and creep.
- Peel off
Phenomenon:
1) Operating surface peeling
2) After peeling, it shows obvious concave convex shape
reason:
1) Excessive load and improper use
2) Poor installation
3) Poor accuracy of shaft or bearing box
4) The clearance is too small
5) Foreign object intrusion
6) Rust occurs
7) Hardness decrease caused by abnormal high temperature
measures:
1) Re study the usage conditions
2) Re select bearings
3) Rethinking the clearance
4) Check the machining accuracy of the shaft and bearing box
5) Research on the design around bearings
6) Methods for checking installation
7) Check lubricants and lubrication methods
2、 Burns
Phenomenon:
The bearing heats up and discolors, causing burns and preventing it from rotating.
reason:
1) Too small clearance (including deformation parts with too small clearance)
2) Insufficient lubrication or improper lubricant
3) Excessive load (excessive preloading)
4) Roller deflection
measures:
1) Set appropriate clearance (increase clearance)
2) Check the type of lubricant to ensure the injection amount
3) Check the usage conditions
4) Prevent positioning errors
5) Check the design around the bearing (including bearing heating)
6) Improve the assembly method of bearings
3、 Crack defect
Phenomenon:
Partial gap and crack cause
1) Excessive impact load
2) Excessive interference
3) There is significant peeling
4) Friction cracks
5) Poor installation accuracy (excessive corner circle)
6) Poor use (using a copper hammer, getting stuck with large foreign objects)
measures:
1) Check the usage strip
2) Set appropriate interference fit and inspect materials
3) Improve installation and application methods
4) Prevent friction cracks (check lubricant)
5) Check the design around the bearing
4、 The holder is damaged
Phenomenon:
1) Loose or broken willow nails
2) Holder rupture
reason:
1) Excessive torque load
2) High speed rotation or frequent speed changes
3) Poor lubrication
4) Inserting foreign objects
5) Large vibration
6) Poor installation (installed in a tilted state)
7) Abnormal temperature rise (resin holder)
measures:
1) Check the usage conditions
2) Check lubrication conditions
3) Re study the selection of retaining frames
4) Pay attention to the use of bearings
5) Study the rigidity of shafts and bearing housings
5、 Scratches and card injuries
Phenomenon:
1) Surface roughness with slight deposition
2）
