What impacts the Bearing Service life and how to increase its lifespan?

The life of your bearing depends upon various factors that are beyond the normal maintenance conditions. The bearing service life is prolonged when under actual conditions it is kept under strict monitoring before it actually fails or stops working. 

By considering the many variances, the question arises as to what typical conditions ‘under strict monitoring’ elongates the life of the bearing?

The Running Temperature:

The right materials require the right temperatures. All the components in equipment are made with different sustainable materials that require the right amount of heat which is not too hot. The temperature provided may affect the press fits and might result in abnormal thermal expansion and contraction, which also impacts the shaft movement and the bearing ID. Thus they contribute to the total life of the bearing. 

Affect on Lubrication:

High temperatures decrease the lubrication between the bearings since the grease life is cut for every 15 degrees above the rise of 70 degrees. The lubricant viscosity becomes low, which reduces the life of the bearing; without a good lubrication level that includes both manual grease rolling bearings and self-lubricating composites, friction will start building. 

Dust and other contaminants also affect the bearing’s life.

Check out the leaded bronze bearings that can effectively take heat upto 250 degrees, are friction efficient, and include oil and grease. 

Bearing Load:

The potential of any application to bear the load determines the life of the bearing. Loads in construction applications where loads are uneven further deteriorate the life of the bearing. Thus the bearing should be built to carry heavy capacity. Having good resistance and the capacity to bear heavy loads, Kormax’s heavy-bearing bronze are a good fit for any equipment. 

The Speed:

Generally, the high speed for a bearing is 500fpm to 3000fpm. The linear speed indicates the conditions that dictate the bearing’s life and design at the pitch line of the bearing capacity. Thus, if bearings are not coordinated with the speed per minute of the rotatory application, they will wear out quickly and adversely affect the life of the bearing.  

Foreign Contamination:

When foreign substances interfere with the bearing lubricants, including dust, grit, dirt, steel chips from contaminated areas, or dirty tools, it causes the lubricating bearing to lose its potential. Thus denting and rollaway of rolling elements that cause vibrations should be watched out for.  

Improper Mounting:

Bearings should be mounted with a rotating ring. Certain conditions can cause denting, high operating temperatures, or early failures of bearings. They include mounting the bearings on shafts by applying unequal pressure, mounting bearings into housing by pressing on the inner ring, loose shaft fits and housing fits or even excessively tight fits, and a poor finish on the bearing seat.

Proper mounting instructions should be followed to understand the difference between a properly and improperly installed mounting.

Thus many more factors contribute to the wearing and tearing of the bearing. Bearing is the essence on which the whole equipment works, and thus the better the bearing matches your environment, the better it will last. Thus if they are maintained properly, the equipment also works just fine, which is important for smooth maintenance of any business or work, especially related to small construction where the whole business relies on the earth moving heavy-duty equipment.
