Product Overview
Neylite Babbitt Metal 300B is a proprietary lead-tin base babbitt bearing alloy from the Neylite line, hardened with antimony and copper, used to line plain bearings in industrial machinery. Like all babbitt metals, it combines a soft matrix with harder intermetallic particles, giving a bearing surface that conforms to the shaft, embeds dirt and wear debris instead of scoring the journal, and runs smoothly under boundary lubrication. Neylite grades have been poured by bearing shops for decades, and 300B is supplied to its established chemistry so that rebabbitted bearings match the originals. It melts over a range of roughly 372–500°F (189–260°C), is typically poured at about 650°F (343°C), and has a density of about 0.312 lbs/in³ (8.63 g/cm³). Forms: 4-5 lb Ney ingot, sized for melting pots and ladle pouring.
