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.

Heat Wands

NEMA 5-15

Shaped like a large flashlight, this wand loosens stuck nuts, heats bearings, and repairs dents. It uses magnetic induction to heat but does not magnetize parts.

Digital 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.

Crossbar Induction Bearing Heaters

NEMA 5-20

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.

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. The power cord requires a plug (not included).
