Although there are many different components that go into a piece of machinery, one of the key components, if present, is going to be the bearings. They help to keep things moving, and when they are operating properly, they can add to the smooth operation and productivity of the task at hand.

Unfortunately, bearings can also be a source of problems. And when problems occur, there can be issues with the machinery as well as the possibility of a catastrophic failure. Often when thinking about problems with bearings the topic goes to lubrication. But that’s not the only concern…

The design, cleanliness, and maintenance of bearings are all extremely important. However, it often seems that the installation of bearings is handled quickly and poorly.

Properly installing a bearing is just as important as the factors mentioned above. If not properly installed, the bearing may be damaged. One type of damage, brinelling, is a serious problem for bearings and leads to unwanted noise, vibration, and malfunctions.

In many cases, bearings are improperly installed because the person installing them believes certain myths or misconceptions.

Over 15% of premature bearing failure can be attributed to a poorly fitted or mounted bearing, usually one that was mounted using too much brute force as opposed to proper mounting practices.

Installation is the first point of contact for your new bearing parts and your machine. It is quite important that you don’t go slapping on new bearings willy-nilly, as proper mounting is essential to ensuring long bearing life.

There are proper procedures and tools to help you perform installation properly. Check with the manufacturer and your distributors first, if you have questions regarding any specific application or issue.

There are tools and even nifty installation kits on the market to assist in facilitating safe, precise, and quick mounting of bearings. These help to avoid any damage to the shaft or raceways during mounting.

Remember, mounting isn’t a one and done-type ordeal. You will want to be certain your bearings are properly dismounted, and re-mounted after every maintenance endeavor, in order to ensure the longest-running life from them.
