The SKF TIH L77 is a very large induction heater for hot bearing mounting. The TIH L77 is characterised by its extended operating area that allows very large bearings to be heated. The sliding yoke supports an ergonomic workflow and the heater can easily be transported by forklift. The TIH L77 is designed for very wide bearings weighing up to 1200 kg.
Extended operating area for very wide bearings
Standard sliding yoke for ergonomic operation
Easy and safe to use with automatic temperature control or time controlled heating
Automatic demagnetization reduces risk of bearing contamination
Automatic temperature hold function to keep the bearing hot after completion of the heating cycle
