Induction heaters
Heating a bearing so it expands is the safest way to mount an interference fit. An induction heater warms it from the inside under control: unlike a flame or an oil bath it leaves no contamination, it measures the temperature, and it stops before the usual 120 °C limit — past which the hardness of the bearing steel is permanently lost.
Types and variants
The distinct designs that sit under this category.
Portable compact heaters
For field maintenance on small and medium bearings.
Workshop heaters
High capacity with adjustable yokes, for heavy bearings.
With automatic demagnetisation
Leave no residual magnetism, so the bearing does not attract swarf.
Temperature probe and monitoring
Control from the bearing's own surface temperature — it stops on a reading, not on a timer.
Where it is used
The applications this category most often serves.
- Electric motor and pump overhauls
- Gearbox and transmission maintenance
- Paper, cement and steel plant maintenance
- Any workshop that changes bearings
What we ask when selecting
What we need in order to find the right part. You do not need all of it — we can work out the rest together.
- Weight and size of the largest bearing
- The figure that sizes the heater.
- Supply voltage and power
- The workshop supply has to cover what the unit draws.
- Portability
- Field work and bench work mean different classes of device.
- Temperature control and demagnetisation
- Neither is an extra — both protect the life of the bearing.
Typical designations
Examples that make the designation readable — not a stock commitment.
- TIH 030m
- Portable class, for small and medium bearings.
- TIH 100m
- Workshop class with high capacity for heavy bearings.
Other categories in this group
Send us the designation or the dimensions — we will find the match.
A code you cannot find in the catalogue, a faded marking on an old bearing, or just the dimensions — any of the three is enough. The wrong bearing costs more than a late one.
