Cheap Bearing Heater

[junquecol]

Today, I was changing out some bearings on an electric motor. Used puller to remove old ones. Took the new ones, one at a time and set it on top of a 60 watt light bulb (lit of course) for about three minutes. Wearing a leather glove picked up bearing an dropped it onto the shaft.

Just a light bulb to heat up the metal enough to make it expand and it just slide right on the shaft???


WOW thanks for the Info.
