SKF Bearing Heater, 1200kg Maximum Bearing Weight, 150mm Minimum Inside Diameter - TIH L44/MV

This bearing heater is an induction-based device designed to expand bearings for interference-free mounting in industrial settings. It operates from a three-phase supply and is intended for processing large, heavy bearings where controlled thermal expansion is required.

Features and Benefits:

• Rated for heavy loads enabling handling of 1200kg bearings
• Compatible with shafts from 150mm internal diameter for tight fits
• Operates from 400V–460V supplies to suit facility power systems
• Induction heating method providing rapid, contactless warming
• Designed for use with large assemblies to reduce press-fit forces

Applications

• Suitable for mounting large roller and ball bearings in mechanical plants
• Used for preheating bearings prior to assembly on heavy-duty shafts
• Ideal for maintenance workshops handling high-mass rotating equipment
• Can be used for thermal fitting during gearbox and motor rebuilds

What electrical supply is required to run this unit?

It requires a three-phase industrial supply rated at 400V or 460V and should be connected by qualified personnel.

How does the system cope with very heavy components?

The induction method heats the inner ring evenly, allowing bearings up to 1200 kg to be expanded without mechanical distortion.

What is the smallest bore that can be accommodated?

It supports bearings with internal diameters from 150mm upwards, making it suitable for medium-to-large shafts.

Is physical contact with the bearing necessary during operation?

No, induction provides contactless heating of the inner ring, reducing handling risks and contamination.
