The SKF TIH 220m large induction heater is designed to heat bearings that are press fit onto a shaft. Heating causes the bearing to expand, eliminating the need for mechanical installation force.
This user manual explains the purpose, working principle, and key features of the SKF TIH 220m induction heater, which is designed for heating bearings and other ferromagnetic workpieces. It includes safety information, component descriptions, technical parameters, wiring instructions, and step‑by‑step operating procedures.
The document also covers safety protection functions, troubleshooting codes, spare‑part numbers, and recommended practices for handling heat‑sensitive bearings. All instructions are presented in Chinese and comply with EU low‑voltage and EMC directives. This manual is written in Chinese.
