The reason for the damage of the bearing holder of the sand suction pump

The reason for the damage of the bearing holder of the sand suction pump

The retainer is the weakest link of the bearing. The damage depends on whether it is individual or batch damage! If there is a certain proportion of damage, 

please verify:

1. The interference fit and bearing clearance of the bearing;

2. Can the lubrication of bearings meet the high-speed, high-temperature, and high load requirements of bearings;

3. Whether the bearing has water ingress;

4. Whether the sand suction pump has axial load and whether the bearings can withstand it;

5. Calculate and design the lifespan of bearings.

The main reasons for damage to the bearing cage of the sand suction pump include the following:

Insufficient lubrication: Failure to add lubricating oil or grease in a timely manner after it has dried up, resulting in insufficient lubrication of the bearings and causing 

severe wear.

Improper installation: Improper operation during installation may result in the breakage of the cage and other adverse conditions.

Foreign object intrusion: Dust and other foreign objects enter the interior of the bearing, increasing the friction between the rolling elements and the cage, resulting 

in damage to the cage.

Shock and vibration: The shock load and vibration borne by the bearing can cause the rolling elements to collide with the cage, resulting in damage.

Abnormal temperature: The internal temperature of the bearing is too high, which hinders the movement and rotation of the cage, exacerbating wear by 24 degrees.

Material defects: Defects in the material of the cage, such as cracks, metal inclusions, etc., may also cause damage to the cage.

Preventive measures:

Ensure lubrication: Regularly check and replenish lubricating oil or grease to ensure that the bearings are always in good lubrication condition.

Correct installation: Install strictly according to the operating procedures to avoid damage caused by improper installation.

Maintain cleanliness: During assembly and use, ensure that the environment around the bearing is clean to prevent foreign objects from entering.

Reduce vibration and impact: Take measures to reduce the impact and vibration borne by bearings, such as using shock absorbers.

Temperature control: Monitor the bearing temperature to avoid excessive temperature and take necessary cooling measures if necessary.
