Few More Information on Bearing Heaters for You to Know

Metals and other conductive materials can be bonded, hardened, or softened using the induction heating method. Induction heating offers a compelling mix of speed, control, and consistency for many contemporary production processes.

Gear, bearing, sprocket, and many other machine parts can be assembled or disassembled with the help of a bearing heater (เครื่อง heat bearing skf, term in Thai) by applying heat. The inner ring of the bearing is heated, which generates thermal expansion and makes it possible to mount or demount the bearing or gear without risking damage.

As the bearing heats up, a temperature sensor attached to the inner ring of the bearing monitors the temperature, which is normally between 230° and 250° F (110° and 120° C). To minimise overheating, some heaters are equipped with programmable thermostats.

For maximum bearing life and optimal bearing performance, proper bearing alignment is essential. An incorrect installation might lead to an alignment issue with the shaft and early bearing failure.

The inner ring of the bearing will gently expand after being heated by a bearing heater (เครื่อง heat bearing skf, term in Thai), making fitting the bearing on the shaft simple and error-free. The bearing creates an interference fit once it has cooled. Induction shrink fitting is the term used to describe this procedure.

The requirement to push or hammer cold-mounted bearings, which can result in misalignment and shorter bearing life, is eliminated with bearing heater (เครื่อง heat bearing skf, term in Thai). They are also a more secure substitute for a hot oil bathor torch, which are less accurate heating methods and increase the danger of user damage.

Never use a torch directly on a bearing since it can cause damage. Oil baths provide handling risks, require a long time to fully heat the bearing, and may be filthy.

Advantages of Induction Heating

Induction heating has the following benefits over some of the traditional heating methods (such as flame heating, resistance heating, furnaces, etc.):

1. Reduced time

By directly heating the target with induction heating, heating time and heat loss are reduced. High power density and little to no thermal inertia are provided by this technology.

2. High efficiency

Due to the power converter and coil’s excellent design, efficiency values of over 90% are achieved. Additionally, because to the greatly reduced ambient heat loss, high temperatures may be reached rapidly and easily.

3. Improved control

Through proper coil design and power converter management, the heating power may be precisely regulated. As a result, more functions could be added, like local heating, pre-heating, and predetermined temperature profiles.

4. Industrial automation option

Both productivity and process quality can be improved using induction heating. Additionally, since the heating is contactless, quality is assured.

5. Safety and cleanliness

Since the target is directly heatedand no fuel chemicals are used, there is no air or thermal pollution.

The aircraft and car industries promoted the use of induction heating technology throughout the Second World War and after. The spectrum of induction heating applications was greatly expanded by the use of induction heating for advanced material treatment in addition to metal melting.

For a wide range of applications, induction heating technology today offers extremely efficient and dependable solutions.
