What Are The Benefits of Bearing Induction Heaters

Induction Heater

 

One of the objectives of proper bearing installation is to achieve radial retention of the bearing rings on their respective seats. The recommended method for achieving radial retention is to create interference, or press fit between the bearing ring and its seat. The force needed to mount a bearing increases rapidly with bearing size. Because of the mounting force required, it is more efficient to use the heating method to mount the bearings. There are different methods to heat the bearings, such as oil baths, open flames, ovens and induction heaters. Bearing induction heaters are becoming more and more popular in the modern world. Big part of it are safety and environmental regulations.

 

Advantages of bearing induction heaters:

 

  • Environmentally friendly: no smoke, no open flames, no fumes, no oil waste

 

  • Temperature control. The temperature probe is monitoring the temperature and turns off the heater when desired temperature is reached. This feature is very important because overheating will damage your bearing. If the bearing is heated to a temperature greater than 125 °C (257 °F), the material may change metallurgically and produce alterations in diameter or hardness.

 

  • Most of the modern induction heaters have automatic reheat mode. Which means when the set temperature is reached and heater is off the temperature probe is still monitoring the workpiece and has certain range. When the temperature falls below the allowable range the heater goes on. This way it maintains the temperature.    

 

  • Much faster and evenly distributed heating. An alternating electro-magnetic field induces a high current directly in the workpiece. This increases the temperature of the workpiece much faster than oven torch or the oil bath. Ovens and hot plates are often used for batch heating of small bearings and this is an acceptable technique. However, for larger bearings, the use of ovens and hotplates is generally quite inefficient and time consuming and can present the operator with significant handling hazards.

 

  • Safety. During heating process only the workpiece is heated, while the device itself remains cool. This reduces the chances of fire in work area and the operator to get hurt. In case if the operator is distracted, the heater will turn off after the temperature is reached.

 

Typical applications for induction heaters are bearings, hubs, sprockets, compression rings,labyrinth rings, sleeves, joints.

Induction heaters are the modern, efficient and safe way to heat bearings. In operation, they are generally faster, cleaner, more controllable, and easier to use than other heating methods.

All these may sound too good to be true and you probably think what are the trade-offs? 

The induction heaters may cost more than the other methods listed above, but long term, the total cost of ownership is often significantly lower.
