I was asked how an induction bearing heater worked.I thought I knew untill i started talking. Is the bearing the secondary of the transformer or is the bar through it the secondary and the hi oscillation curents induced into the bearing are what heats it.I really tried to search google with no luck..

I don't know if it's what you need....

Remember: once heated, pass the bearing through the U to demagnitize.

An idea: here's something I use but can't recommend ------- 300 w light bult on a pedestal and board mounted bult sitting vertically. Sit the bearing atop the bult carefully and it'll heat it fast (must monitor to avoid over-heating). Care not to break the bulb and grease free ---- but it does work very well and will get you out of a crunch when ya gotta.

Thanks for the answers guys. I thought the bearign was the secondary of the transformer.
Your light bulb idea is good sam i will keep that in memory storage .I am sure one day our heater will break and we will need an emergency bearing heater.

We offer a large variety of induction bearing heaters. Data sheets and manuals may be downloaded explaining their operation.
