The steel sleeve chain for engineering is mainly based on ASME B29.12M "Steel sleeve (no rolling) chain, attachment and sprocketing tooth shape", JB/T 5398 "Steel sleeve chain, attachment and spindle", JB/T 3926 "Vertical Fighting Raiders" and other standards can be designed and manufactured for custom development. The steel sleeve chain for engineering is evolved from the early cast chain. The design of the chain -based function and the long service life of the chain has a larger than the chain bearing area. Performance products are mainly used in various engineering machinery purposes such as conveyor, bucket improved, and electric equipment. In some major projects, the loose material transport chain of many heavy -duty -type improved machines use a steel sleeve chain.
