In the realm of rotating machinery, babbitted bearings stand as a testament to durability, reliability, and cost-effectiveness. These bearings, renowned for their ability to withstand heavy loads and challenging operating conditions, have been the backbone of countless industries for over a century.
Babbitted bearings derive their name from the babbitt metal that forms their lining. Babbitt metal is an alloy primarily composed of tin, antimony, and copper, offering exceptional bearing properties. The bearing lining is cast directly onto a steel or cast-iron backing, creating a strong bond that ensures structural integrity.
