Understand how bearing heaters reduce shaft damage and improve bearing fit.
Hot-Plate Bearing Heaters
 |
Shown with Bearing |
Set one or more bearings flat on the plate. This heater has a thermostat that adjusts from 120° to 390° F and lights that indicate when the plate has reached the desired temperature. It’s housed in a metal case that minimizes heat loss and keeps dirt out of your bearings. In case of overheating, the heater will shut off.

Heat Wands
 |
Shaped like a large flashlight, these wands loosen stuck nuts, heat bearings, and repair dents. They use magnetic induction to heat but do not magnetize parts.

Digital-Display Crossbar Induction Bearing Heaters
 |  |
NEMA 5-20 |
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
 | |
NEMA 5-20 |
Compact enough to take with you, this heater has a clamp that holds and heats bearings up to 392° F. 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.

Automatic Cone Bearing Heaters
 |  |
NEMA 5-15 |
The thermostat automatically brings the temperature of the bearing to 250° F. Place the bearing over the cone and the thermostat on top of the bearing. A light indicates when heating is complete.

Crossbar Induction Bearing Heaters
 |
|
NEMA 5-15 |
 |
NEMA 6-20 |
Heat bearings much more quickly and uniformly than cone 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 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.

Manual Cone Bearing Heaters
 | |
NEMA 5-15 |
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.
