Poor lubrication of bearings in Dalian can result in the following consequences:

Poor lubrication of bearings in Dalian can result in the following consequences:

1、 Increased wear and tear

Dry friction: When there is a lack of lubricant, the rolling elements of the bearing will come into direct contact with the raceway, resulting in dry friction. This dry friction will significantly increase the friction coefficient, causing rapid wear of the metal material on the contact surface and reducing the dimensional accuracy of the bearing.

Abrasive wear: Poor lubrication may also allow external impurities and particles to enter the interior of the bearing. Due to insufficient lubricant to remove these particles, they can cause scratches and wear on the bearing surface during rolling, further exacerbating the damage to the bearing.

2、 Temperature increase

Friction induced heat generation: Due to insufficient lubrication, frictional resistance increases, and a large amount of heat is generated during the operation of the bearing. And these heat cannot be effectively dissipated through lubricants, leading to a sharp increase in bearing temperature.

High temperature effects: High temperatures can reduce the hardness and strength of bearing materials, further exacerbating wear. Meanwhile, high temperature may also cause changes in the clearance inside the bearing, affecting its normal operation and service life.

3、 Shortened fatigue life

Stress concentration: Poor lubrication can cause uneven loads on bearings during operation, leading to local stress concentration. This stress concentration will make the Dalian bearing material more prone to fatigue cracks, thereby shortening the fatigue life of the bearing.

Crack propagation: Once fatigue cracks occur, due to the lack of lubricant protection, the cracks will rapidly propagate under high stress and friction, leading to bearing failure.

4、 Increased noise and vibration

Surface roughness increase: Wear will increase the roughness of the bearing surface, and the rolling elements will produce irregular vibrations when moving in the raceway, resulting in abnormal noise.

Gap variation: Wear and temperature rise may cause changes in the internal clearance of the bearing, resulting in a decrease in the fitting accuracy between various components during operation, as well as additional noise and vibration.

5、 Increase equipment maintenance costs and downtime

Frequent maintenance: Various problems caused by poor lubrication of bearings will require more frequent maintenance or replacement of bearings. Each repair requires manpower, material resources, and time, which increases the maintenance cost of the equipment.

Equipment shutdown: Severe Dalian bearing failures can cause equipment shutdown, affecting production progress. Moreover, the production losses during equipment downtime and the time and cost required to restore production cannot be ignored.
