We replace white metal/babbitt in bearings of all sizes, from small to large (over 500mm). We use highquality centrifugal casting for complex bearing repairs, and manual casting for large bearing repairs. During the repair process, we control the melting pot temperature to preserve metal properties.

Semilubricated journal bearings consist of a shaft rotating in a porous metal sleeve of sintered bronze or aluminum in which lubricating oil is contained within the pores of the porous metal. These bearings are restricted to low loads, lowtomedium velocity and temperatures up to 100°C (210°F).

Feb 03, 2020· Bearings in an engine are used to support moving mechanical parts and protect those parts from frictional degradation. The heavier and more powerful the engine, the stronger the bearings must be to provide this support and protection. In 1839, a special material called Babbitt metal was developed.

Babbitt bearings are manufactured with the white metal lined onto steel, cast iron and copper base alloys. Since white metal suffers a reduction in fatigue strength with increase in temperature, and this reduction is a function of thickness, it is usual to limit the thickness to between about mm, and thicknesses of only ...
