Induction Heater For Bearing Fitting

Heating bearings makes them easier to install and reduces damage to shafts during installation.

Induction heater for bearing fitting.

As small as that bearing is you need to heat to at least 250 you ll need all the slack you can get to avoid it grabbing halfway on.
