Whitemetal lined bearings are sacrificial parts, so their “failure” is part of their function in order to protect the more valuable rotating elements of a machine. At a fraction of the time and cost, bearings can be repaired and put into service on critical plant with confidence.
Decades of Experience.
Oiltech Bearings has decades of combined experience in repairing whitemetal lined bearings and seals.
Urgent requests are part of our business to meet clients' needs when unplanned outages occur.
Re-engineering part during the repair process allows Oiltech Bearings to provide new parts for strategic spares or future orders.
Repairing bearings follows a robust process with the same ultrasonic and dye penentrant requirement used for manufacturing new parts.
Oiltech Bearings has robust, quality assured process for repair of bearings. If a bearing is deemed un-repairable during inspection, we can re-engineer and manufacture new parts.
