Featuring tin-base and lead-base babbitt to ASTM, SAE, government, Navy specifications; special and custom alloys.

The use of bearing materials to reduce bearing friction can be traced at least back to the Roman chariot days. Soft metals such as Tin and Lead were unsuccessfully tried in the 1700’s; but, it was not until 1839 that Isaac Babbitt patented a bearing with a Steel or Bronze shell lined with a Tin-base alloy. The alloy mentioned in the patent was 89% Tin, 9% Antimony and 2% Copper, which is amazingly close to today’s very popular ASTM B-23 Grade 2 “Babbitt” was originally applied to Tin-base alloys, it is now used to describe bearing metals with Lead or other metals as the major element.

Belmont Babbitt Metals are manufactured under strict metallurgical control to provide sufficient softness for excellent conformability and embeddability, thereby offering good fluid-forming properties. They are easily cast, can be rigidly bonded to Cast Iron, Steel or Bronze, will run satisfactory against a Steel shaft, and show excellent corrosion resistance. Given suitable design of a bearing assembly, a properly selected Belmont Babbitt alloy will give effective service under a wide variety of conditions

In addition the traditional method of pouring molten Babbitt to form the bearing surface, Babbitt is often sprayed onto the bearing surface using Babbitt wire in metallizing equipment. The apray method is also used to seal the ends of rolled or stacked electronic condensors.

Belmont offers a broad range of both Tin and Lead-base Babbitt alloys to meet requirements for most common applications. We also invite inquiries on Cadmium-base, Copper-base, Aluminum-base, and Zinc-base bearing alloys.

Forms Available

Belmont Babbitt metals are provided as 40-lb. ingots, or as smaller ingots, six to eight lbs., with five sections, and wire for flame spraying/metallizing applications
