How to remove bearing from hub
Removing and installing bearings is an important skill that demands knowledge of the right equipment, procedures, and expertise. Proper bearing mounting techniques prevent damage to machinery and ensure successful long-term operation. In this article, we look into the methods of using heat for bearing mounting and removal. The use of heating for installing or removing bearings is essential for tight-fitting bearings.
Methods, like torching or heating bearings in a hot oil bath, are difficult and do not have the control of an induction bearing heater
How to remove a stuck bearing from a shaft
The process of removing bearings using heat relies on the principle of thermal expansion. When a bearing is heated, it expands, causing an increase in its inner diameter. This expansion loosens the bearing’s fit, making it easier to remove from a shaft or housing. The key is to apply heat evenly and gradually, typically using a controlled heat source like a heat gun or an induction heater, to avoid uneven expansion or damage to the bearing and the surrounding components. The correct temperature must be reached to ensure sufficient expansion for removal but should not be so high as to alter the metallurgical properties of the bearing. This method is highly effective for interference fits or bearings that have seized due to corrosion or overuse.
The heated bearing removal process begins with gradually heating the bearing, using a heat gun or induction heater, to expand its metal and loosen its fit. It’s crucial to apply the heat evenly around the bearing, avoiding direct flame contact, and to carefully monitor the temperature to prevent overheating. Once the bearing expands, it loosens on the shaft or housing, making it ready for removal. This step should be performed promptly as the bearing will start to cool and contract. Using appropriate tools, the bearing is then carefully removed. Post-removal, allow the bearing and the part it was attached to cool down slowly to room temperature to avoid thermal shock.
Equipment Shutdown and Isolation – turn off and isolate the equipment from power sources. This prevents accidental activation during the removal process.
How to remove bearing from housing
Workspace Preparation – clear the workspace of flammable materials. Ensure adequate ventilation to handle fumes or smoke.
Bearing replacement procedure
Typically bearing induction heaters are safe, clean, and simple for replacing bearings safely, securely, and quickly on a shaft.
Finally, inspect both the shaft and housing and the bearing itself if it is to be reused, for any signs of damage. This detailed process requires a balance of precision, patience, and safety precautions to ensure effective removal without damaging the bearing or the machinery.

Accessibility Check – ensure the bearing is easily accessible for heating and removal. Remove any components that may obstruct the process.
Selection of Heat Source – choose an appropriate heat source, such as a heat gun or induction heater, suitable for the bearing size and material. As mentioned we highly suggest using FAG induction heaters
Bearing induction heating is an easy solution to fit bearings onto shafts. Induction heaters create an oscillating electrical current that causes the bearing or metal to heat when placed in the device’s magnetic field. Eddy currents cause the bearing to heat and expand. Once the induction bearing heater reaches the target temperature, then it is time to remove the hot bearing with safety gloves and place it over the shaft. As it cools down, the bearing shrinks to fit.
Measurement Tools Ready – have tools ready for measuring temperature, ensuring the bearing is heated to the appropriate level without exceeding its material limits.
Arrangement for Cooling -plan how to cool the bearing and machinery part post-removal to avoid thermal shock or warping.
How to remove bearing from shaft with puller
Induction heating is a non-contact, safe method for precisely heating electrically conductive materials, such as bearings, bushings, and gears. The heating process changes the physical properties of the bearing metal and allows the material or workpiece to harden, soften, or bond metals. This is especially useful not only for bearings but also gears, shafts, and axles.
Pacific International Bearing recommends the use of bearing induction heaters to let users control the process of mounting bearings onto a shaft or dismounting them with precision.
Maintenance teams can remove bearings without causing bearing damage or introducing particle contamination. We offer bearing induction heaters from FAG Bearing company which come in large, medium, and small sizes. We also offer a portable bearing induction heater.

FAG induction heaters prevent damage during mounting and dismounting in a targeted manner.FAG induction heating devices can be used for a wide range of applications. These include not only all conventional rolling bearings but also other ferromagnetic steel parts such as gears, clutches, and bushings.
I’m nearing the end of my braces treatment and my orthodontist asked if I thought about if I want clear or metal retainers. I honestly have no idea.
