Heating bearings is a good way to temporarily expand the bearing rings to facilitate mounting without the use of excessive force that could damage bearings. Heaters can be used for mounting or dismounting by efficiently heating bearings and workpieces (gears, sprockets) large and small.Dec 12, 2018
How does a bearing heater work?
When the heater is switched on, a high voltage, low alternating current passes through the numerous windings of the primary coil. This induces a low voltage, high current in the workpiece acting as the secondary coil. This high current results in the heating up of the workpiece.

How much does it cost to install heating bearings?
Now if you are just replacing the wheel bearing in one of your front wheels, these costs will pretty much be split in half. For the total cost, on average, expect to pay around $130 to $220. The parts will cost between $60 and $100, and the labor will cost between $70 and $140.
How much heat can a sealed bearing take?
Seals. The permissible operating temperature for NBR seals is –40 to +100 °C (–40 to +210 °F). Temperatures up to 120 °C (250 °F) can be tolerated for brief periods. Typically, temperature peaks are at the seal lip.
Can you heat bearings with a torch?
Blow Torch The bearing can heat up quickly, but there is no way of checking the temperature of the bearing and even a steady hand will get the bearing well beyond the maximum allowable temperature of 250 F that bearing manufacturers recommend before damage occurs. So, a blow torch is not a good option.Aug 27, 2020
Can I heat a bearing in a oven?
It is also very important that the surface onto which the bearing will be placed in the oven is clean so as to not contaminate the bearing that will be heated. ... Sealed or pre-lubricated bearings should not be heated in an oven as both the seal and the lubricant may be compromised.Jun 16, 2020
How do you check bearing temperature?

What is a bearing induction heater?
Induction heaters (D) are the modern, efficient and safe way to heat bearings. In operation, they are generally faster, cleaner, more controllable, and easier to use than other heating methods.
Are induction heaters safe?
Induction heating can be designed as an intrinsically safe process. There is no external heat source that requires special safety precautions. No oxygen is consumed from the environment, neither are any fumes emitted. Induction heating is all-electric, which makes it a highly deterministic process.
What are induction heaters used for?
Induction heating is used both domestic and commercial cooking, in several applications such as heat treating, soldering, preheating for welding, melting, shrink fitting in industry, sealing, brazing, curing, and in research and development.Jan 27, 2015
What temperature should I heat my bearings?
A good general rule of thumb is to heat bearings to a temperature 150 F greater than shaft temperature. This is sufficiently warm to allow the bearing to slide over the shaft while not hot enough to damage any components. In any case, do not heat open bearings above 250 F.Nov 28, 2017
How do you warm up a bearing?
While ovens, hot plates and oil baths work, the simplest method to heat a bearing is with an induction heater. The process is quick, accurate, repeatable and safe. Make sure operating instructions and warnings are followed because induction heaters create a strong magnetic field which can be a hazard.Nov 28, 2017
