The Main Bearing Assembly is one of the important components of Axial Fan. It is a Bearing arrangement assembled on a shaft and developed so that bearings can be contained rigidly in a clean, lubricated envelope, and be mounted to Fan frames with minimal preparation.

LTH facilities are equipped with bearing heater, tools, instruments and equipment for assembly of bearings on shaft. After assembly to ensure everything is correct, 8 hrs. of rigorous testing is performed on specially designed test arrangement to monitor the bearing temperature. Testing is performed on design load and RPM as per site requirement.
