With each day, technology and product innovations become more centered around convenience and adding ease to our daily lives. In the industrial world, this translates to discovering new ways to achieve greater operational efficiency, whether that’s improving machine systems or streamlining conventional processes, like the removal of a bearing from a shaft.
Our goal is to help workers achieve optimum efficiency by evaluating current industry practices, procedures, techniques or routines and asking the question: “what if there was an easier way?”
The Challenges of Bearing Removal
For hundreds of years, figuring out how to remove bearings from a shaft has been a time-consuming maintenance challenge. This is due to the burrs that are formed when the setscrews are torqued onto the shaft.
Additionally, inefficient standard methods used over time to remove the bearings have added insult to injury, contributing to countless hours of extended downtime, shaft damage and frustration.
Hammer and Drift Method
The most recommended, but not commonly used, standard method uses a hammer and drift. This method utilizes these tools to pound down the burr created by the setscrews during installation. This comes at the cost of leaving scratches and/or gouges on the shaft.
Bearing Puller Method
Another standard method requires a bearing puller. However, adequate space must be available for it to successfully remove the bearing. Similarly to the hammer and drift method, this can also leave scratches and/or gouges on the shaft.
When the hammer and drift and bearing puller methods fail, destructive methods are used as a final attempt to remove a bearing from the shaft. These various destructive tactics use instruments such as: hand-grinders, acetylene torches or big hammers. The force used by these objects also commonly result in unnecessary shaft damage and sometimes personal injury.
An Easier Way To Remove Mounted Bearings
If you’ve tried any variation of these methods and are looking for an easier way, Regal offers a bearing removal solution that requires no “method” at all━the Sealmaster® TIME SAVING™ Performance Ball Bearing. It has patented axial grooves that extend the entire length of the inner ring bore at setscrew locations. This design provides clearance from the burrs, ensuring easy removal in either direction.
A New Removal Process
- Loosen the setscrews
- Pull the bearing off the shaft
*Note: In cases of excessive fretting corrosion, a hammer and drift or bearing puller may be needed to assist the removal.
With no impact to ball path roundness, load and speed rating, or bearing performance, the Sealmaster TIMESAVING axial groove mounted ball bearing allows for easier bearing removal to reduce your extended downtime, while maintaining efficient performance.
Additionally, the axial groove design minimizes the damage to your shaft, previously caused by standard and destructive removal methods – reducing unnecessary replacement costs and extending shaft life.
