Engineered for extreme durability and precision,our large-scale self-reversing screw is manufactured from specially forged materials and undergoes meticulously designed heat treatment processes.This ensures the formation of a dense and uniform hardened surface layer,granting the reciprocating lead screw exceptional wear resistance and the ability to withstand prolonged high-intensity friction.
During operation,the screw operates smoothly and reliably without jamming or lag.Paired with an innovative dual-cable guiding structure,the rope or cable is wound in an orderly,neat,and flat manner.Ideal for various large-scale equipment in shipbuilding and heavy port machinery,this reciprocating lead screw ensures stable and accurate performance,providing a solid foundation for maritime manufacturing.
