Ball bearings are essential part of rotating equipments for centuries. Alike every other thing, these also have some facts about which the user should know. It helps them get maximum work with increased life span of the bearing.

There is no doubt about the importance of ball and roller bearings. These can be seen in almost all the rotating devices. Though people have been using these bearings for centuries, there are still some facts they are not aware of. These facts play vital role in maintenance and proper functionality of the bearings. So to ensure optimum results from the bearings, you should be aware of these facts.

Contamination: This is one of the biggest enemies of almost all the bearings. In around 90% of the cases, the major cause of bearing failure is contamination.

Ineffective lubrication: Many users think that they can lubricate the bearings with any lubricant, oil or grease to make it smooth. But the reality is that one should choose lubricant according to the bearing like for pillow block bearings you might need different lubricant from the one used for cylindrical ball bearing.

Impact of speed and load: To properly estimate bearing’s life and make it work for this time period, check the speed and load on the bearings. Very low or high speed than the required can shorten bearing life. The same is the situation with load. Observation of machine’s speed and load can help you buy right bearing.

Importance of rating: Different companies use rating of 1 to 9 for bearings. It defines the stress and tolerance level of bearings. So check the right rating to buy a most suitable bearing for your equipment. The load ratings also help you decide number of ball bearings required for a particular application.

Right size: In case of bearings, one size does not fit all. Every application needs a specific bearing size to get perfect fit. Loose or very tight bearing can cause premature failure. Shaft and housing of the bearings should have perfect fit and size for smooth functioning. You can take help of ball bearing manufacturers in selection of proper bearing to ensure it ensure maximum load as per the design and machine it is fitted in.

Knowledge of different variations: To ensure right selection of the bearings, it is important to have proper knowledge of different bearing variations for varied load directions and potentials. Some of the common variations include self-aligning, split-race, caged and cylindrical bearings.

Quality: Never compromise with the quality of the bearings to save a few bucks. Improper assembling of bearing or use of inferior quality material can cause serious accidents while putting worker’s life at risk. To ensure quality, right fitting and smoothness, spin the bearing around.
