Steam ball machine used on the self-lubricating copper sleeve is generally used ZCnZn25Al6Fe3Mn3 high brass to do the matrix.

                             Steam ball mechanical self - lubricating copper sets

In order to meet the steam ball (mechanical) manufacturers on the use of rotating parts through the life requirements, our company recommended customers to use self-lubricating graphite copper sets of products; self-lubricating graphite copper sets of products using centrifugal casting high-strength copper alloy matrix, Special formula of solid lubricants; self-lubricating graphite copper sets in the steam ball (mechanical) on the use of very suitable, compared to ordinary copper sets of products, so that self-lubricating graphite copper life longer, and because it can be long-term non-refueling maintenance Steam ball (mechanical) in the course of the use of oil and other phenomena is not easy to maintain the cleanliness of the production line has a positive effect.
