Causes and solutions of common failures of crane bearings

Bearings are a component of the crane's transmission operating mechanism and rotating device. If there is a problem with the bearing, it will seriously affect the normal operation of the crane. The editor introduces the common faults and solutions of rolling bearings and sliding bearings of cranes.

1. Common faults of rolling bearings :

1. The temperature is too high

2. Abnormal sound (continue to mute)

3. Metal grinding sound

4. Filing or impact sound

cause of issue:

1. Lubricating oil is dirty, completely out of oil or too much oil

2. The bearing is dirty

3. Lack of oil

4. Damage to cage and rolling elements

Solution:

1. Remove dirt, replace bearings, check the quantity of lubricating oil

2. Decontamination

3. Come on

4. Replace the bearing

2. Sliding bearing

Common fault: excessive heat

cause of issue:

(1) The bearing is skewed or pressed too tightly

(2) Improper clearance

(3) Insufficient lubricant

(4) Unqualified lubricant quality

Troubleshooting method:

(1) Eliminate deflection and tighten reasonably

(2) Adjust the gap

(3) Add lubricating oil

(4) Change to qualified oil

After the crane has a bearing problem, it should be repaired in time, and the lubrication and maintenance of the bearing should be done to ensure the safe operation of the crane.
