Heavy duty hydraulic cylinder, the core bearer of industrial strength. It is made of high-strength steel, with a sturdy structure that can withstand enormous pressure. The high-precision machining process ensures a tight fit between the piston and cylinder barrel, and the sealing performance is excellent, effectively preventing hydraulic oil leakage. Its powerful thrust and pull can drive heavy machinery to run precisely, widely used in mining, construction and other heavy industrial fields, is a reliable power protection for large equipment.
