Technology and product innovation keep evolving, which makes our daily lives easier and convenient. Also, in the industrial world, discovering certain new ways to achieve much higher operational efficiency in the mechanical systems or streamlining any conventional processes such as installation and removal of any bearing from a shaft keeps improving.
To obtain the full-service life of any mechanical component while installing any roller bearing or radial ball properly is critical. Using any inappropriate mounting methods by taking certain shortcuts like using any torch or a hammer may result in a potential safety hazard or a premature failure.

The challenges faced during bearing removal
People have been trying to figure out for hundreds of years, how to take out bearings from its shaft and people have been doing time-consuming methods, which was because of the burrs that are often formed when any setscrews will be torqued onto the shaft.
Besides, using certain inefficient and time-consuming methods for removing the bearings has ended up with an injury, and as a result, countless hours were wasted and increased downtime, damaged the shaft, and created frustration, etc. Some of the old methods were:
1) Hammer and drift method
The standard method used for removing bearing is by using a hammer and drift. Here these tools will pound down the burr that was created by the setscrews while installing. This will come at the additional cost of leaving certain scratches or gouges on your shaft.
2) Bearing puller method
Also, another standard method will use a bearing puller, and for that adequate space is needed for successful bearing removal. This method can also leave scratches or gouges like the above method.
3) Destructive methods
If both these methods fail then destructive methods are generally used for the removal of bearing from the shaft. Here people use hand-grinders, big hammers, or acetylene torches, and the force is used by all these objects may result in certain unnecessary shaft damage or personal injuries too.
A new way to remove bearings
Here you have to follow these steps:
- Loosen the setscrews
- Then pull out the bearing from the shaft
However, in case there is excessive fretting corrosion, then either hammer/drift or bearing puller method may be needed for helping the removal.
In this new method, there will not be any impact on your ball path roundness, speed and load rating, or your bearing performance. Also, the axial groove design will minimize the shaft damage, previously caused due to standard and destructive methods of removal, reducing unnecessary costs of the replacement and extended shaft life.
For achieving the full-service life of any component, it is very critical to install and remove roller bearing in a proper manner. All the necessary safety issues must be addressed, and also enough time must be given for the job so that the procedure is properly understood before the work starts.
