7 Things to Do when Using an Induction Heater for Bearings, Sleeves, Couplings, Crane Wheels and Gears
- Make sure the surfaces of the vertical posts are clean.
- Improve the contact between the vertical post and the crossbar by applying a light coat of Vaseline or grease to the contact surface of the vertical post.
- The temperature probe should always be placed on or as close as possible to the inner race or ID of the workpiece being heated.
- When possible make sure a second probe is placed on the outer race or OD of the workpiece being heated to also track the temperature of the OD, in line with the ID probe.
- For the most efficient heating, always use the largest possible crossbar that will fit through the ID of the workpiece being heated. Stacking of multiple crossbars is permissible.
- It is not a requirement that the workpiece must touch the crossbar(s). Just so long as the bar goes through the bore (ID) someplace.
- Most important of all is that the workpiece being heated always be automatically demagnetized. Any induction heater that does not do this automatically COSTS you money instead of saving it.
