The ‘DWT MOT’ Series Automated Hydraulic Bearing Extractor is a specially designed compact, mobile equipment for dismounting spherical roller bearings shrynk fitted (i.e. direct mounted) on cylindrical journals of wheel sets of ICF Coaches (BG/MG) and EMUs of Indian Railways.
This is the latest addition to INVENTUM’s Range of Hydraulic Extractors based on Oil Injection System and has greater productivity to the manually operated Extractors.
The dismounting procedure is based on Oil Injection System. In the oil injection system the pressurised oil is injected between the bearing and the journal surface and forms a thin oil film eliminating metal to metal contact. The bearing virtually floats out on this oil film without scoring the journal.
