tablished in 1948 as a small foundry, PBW started its operations by producing castings for brass items. In 1953, a small workshop was added to manufacture brass buttons, tumblers and strainers. By 1965, PBW gained significant experience in casting and finishing of nonferrous components. Around this time, there was a need of developing critical components like bimetal bearings, which was identified by PBW then. Initially these were made for slow speed diesel engines. However in 1980, high grade precision bearings were introduced for high speed engines, compressors and earthmovers.
