DESCRIPTION:
TECHNICAL DATA:
29240 is an atomized Tin-based alloy powder suitable for coating application using combustion thermal spray equipment such as the TeroDyn®2000 or TeroDyn 3000 systems when equipped with the specially designed low temperature LT Accessory Air Shroud Package. The Tin alloy is similar to SAE 23 type II Babbitt. It can be used for rebuilding most common tin-based babbitt bearings. It is not recommended for those containing significant amounts of lead.
