Heating bearings makes them easier to install and reduces damage to shafts during installation. Heat expands the bearing's inner race for a snug fit without forcing a tight-fitting bearing onto a shaft. Bearing heaters can also be used on gears,sprockets,pulleys, and bushings.Inductionbearingheaters use magnetic induction to heat but do not magnetize parts.
