Bearing Heaters

The benefits of using a bearing heater to mount a bearing include:

Ensure consistent temperature

Bearing heaters ensure that bearings are heated evenly, guaranteeing a consistent temperature throughout the bearing. This helps to prevent bearing and seal damage during fitting.

Improved worker safety

When used correctly, bearing heaters can greatly improve worker safety, when compared to other fitting methods using heat, such as the use of naked flames or oil baths.

Increased productivity

Bearing heaters are a fast and efficient method of heating a bearing, helping to reduce downtime and labour costs during fitting.

Enhanced service life

When compared to methods such as brute force, using a bearing heater can greatly enhance service life. This is because the chance of the bearing and other surrounding components incurring damage during the fitting process is greatly reduced.

Bearing heaters play a key role in building and maintaining power transmissions, and allow you to install bearings without excessive force, which may damage them.

Bearing heaters are also used for shrink rings, gears, bushings and pulleys, but the heated part must form a closed electrical circuit.

The types of bearing heaters include:

Induction coil bearing heaters - Induction coil bearing heaters are widely available and most commonly used. They use an interference fit mounting to evenly distribute heat to the bearing.

These heaters are suitable for bearings of up to 4.5kg, and can be incredibly helpful due to their portability. Due to the coil sitting on the outside of the heater component, they are also very energy efficient, and heating periods may be greatly reduced.

Hot Plate Bearing Heaters - Typically used for smaller bearings and other related parts, this bearing heater has a flat plate, which heats the bearing up to the desired temperature. These bearing heaters are ideal for heating bearings in one spot, and can reach temperatures of up to 200 degrees.

Cone Style Bearing Heaters - These heater types are designed to manage a range of bearing sizes, transferring heat from the cone to the inner ring of the bearing.
