About Bearing Heaters
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. Induction bearing heaters use magnetic induction to heat but do not magnetize parts.
Crossbar Induction Bearing Heaters
Heat bearings much more quickly and uniformly than cone-style and hot-plate heaters. These heaters use magnetic induction to heat but do not magnetize parts. Slide the bearing onto the crossbar and flip the switch to heat the bearing to 250° F. Heaters includes two sizes of crossbars to accommodate a range of IDs. For the fastest heating, use the largest crossbar that fits through your bearing. Heaters can also be used for demagnetizing. Temperature-indicating crayons (not included) are recommended.
Riser blocks (sold separately) lift the heater’s crossbars to accommodate larger OD bearings.

Digital Crossbar Induction Bearing Heaters
Use the digital control to set the temperature from 230° to 482° F. This heater uses magnetic induction for even heating and automatically demagnetizes bearings. Slide the bearing onto the crossbar and place the temperature probe on the bearing. The heater beeps and shuts off when the set temperature is reached. It comes with three crossbars to accommodate a range of IDs. For the fastest heating, use the largest crossbar that fits through your bearing. A circuit breaker prevents overcurrent and overheating.

Portable Induction Bearing Heaters
Compact enough to take with you, this heater has a clamp that holds and heats bearings up to 3 15/16" ID. It uses magnetic induction to quickly and evenly heat bearings but does not magnetize them. Set the desired temperature and the display will flash when it has been reached.

Manual Cone-Style Bearing Heaters
Place a bearing over the cone to heat. Mark the bearing with the included temperature-indicating crayon; it has reached 250° F when the crayon melts.
