Every day, advances in technology and products focus more on comfort and ease of life. This is to find innovative ways to improve operational efficiency in the industrial sector, whether it is upgrading machinery systems or rationalizing existing procedures, such as removing a shaft bearing.

Our aim is to assist employees in achieving optimal efficiency by assessing existing industries, methods, techniques, or routines and to ask, what if there is a more convenient route to remove a stuck bearing from a shaft. There are multiple methods that can be used to do this process, once such effective way is 50 ton hydraulic 3 jaw bearing puller. However, before proceeding forward we must first reflect on the challenges involved.

Challenges of stuck bearing

It has been a time-consuming maintenance problem for centuries to figure out how to remove rooms from a shaft. This is due to the burrs generated by torquing the set screws into the shaft. In addition, inefficient traditional techniques for removing bearings over time have produced injuries, which contribute to hours of prolonged downtimes, shaft damage, and frustration. 

This is why this is going to be the perfect guide for you in order to find various solutions to remove a stuck bearing with ease.

Solutions Proposed

  • Method of Hammer & Drift

The conventional approach is the hammer and drifting, the most recommended but not often used. This approach uses these tools to lower the burr that is generated during installation by the set screws. This will cost you scratching or gouges. This will cost you the shaft.

  • Method of Bearing Puller

A conventional approach also requires a puller bearing. A sufficient room must, however, be provided to remove the bearing effectively. This may also create scratches and/or gouges on the shaft, similar to the hammer and drift approach.

  • Method of destruction

When the drift and drift techniques fail, destructive measures are employed to remove a bearing off the shaft. Equipment such as hand grinders, acetylene torches, and major hammers are used for different damaging techniques. The force utilized for these things also leads to needless shaft damages and human injuries on occasions.

  • Cold disassembly

Use an appropriate push to tap the side of the loading ring to release it from the shaft when removing a smaller bearing. A mechanical puller is a superior way of using it. Pulling operates on the inner or surrounding ring. If the ramp is between the shaft shoulder and the holder is taken by the holder. This makes the demounting procedure easier. In order to allow the bolts to push the rooms out, create several threaded loops on the bore shoulders. Large and medium-sized rollers often need greater strength than mechanical instruments. The use of hydraulic tools or oil injection techniques, or both, is thus suggested.

  • Thermal disassembly

The heat disassembly method is suited for the removal of the inner ring of needle roller covers. Heating rings and adjustable induction heaters are two popular instruments of heating. Install and remove the inside ring from an SMB bearing of the same size using the heating ring. You should pick a light-alloy ring with the heating ring. The ring features an electrically isolated handle and a radial slot. Debuggable induction heaters are recommended when inside rings are regularly removed with changing diameters. Without heating the shaft, these heaters may heat the inside ring fast.

Conclusion

These methods are not on any priority list and are best suited according to your needs. This article aims to provide solutions to problems that may arise or have arisen. By utilizing this knowledge the process of removing a stuck bearing from the shaft would be very easy.
