White metals of varying grades have long been used as an anti-friction material for lining bearings. The applications include bearings for turbines, gearboxes, internal combustion engine crankshafts, stern tubes and fans.
As with other metal replacement processes, white metaling depends on thorough preparation, top class quality control procedures and a wealth of experience, not only to carry out the work, but also to select the appropriate grade metal.
New metal, to a national or international standard, is always used as premature failure from inclusions and gas induced cavities can occur through using reclaimed material.
Temperature controlled melting pots ensure the metal properties are maintained at the highest level and non-destructive testing, such as ultrasonic, is then used to check the quality of the bearing and its bonding with the supporting shell.
The Company's extensive machining facilities mean that the finishing of bearings is equally controled in respect of quality and delivery.
