Construction Machinery Hydraulic Cylinder, designed specifically for booms, arms, buckets or travel mechanisms of heavy-duty construction machinery such as excavators, loaders and bulldozers, is a key linear power actuator in the hydraulic system. It converts hydraulic energy into mechanical energy by pushing the piston rod to extend and retract under the pressure of hydraulic oil, providing stable and powerful thrust for equipment actions such as lifting, digging and steering, ensuring reliable operation of the equipment under heavy-duty and harsh working conditions such as mines and construction sites. The cylinder barrel of the product is made of high-strength alloy steel, integrally formed by cold drawing/forging process with dense structure and strong pressure resistance, which can withstand high-pressure impact and alternating loads without deformation or cracking. The inner wall of the cylinder barrel is precision honed with low surface roughness, achieving leak-free operation with the matching seals. The piston rod is made of high-quality alloy steel, strengthened by quenching and tempering treatment + hard chrome plating process, with high surface hardness, excellent wear resistance and corrosion resistance, which can withstand heavy loads and reciprocating motion for a long time without wear, corrosion or scuffing.
The cylinder head and bottom are made by forging process with high strength and impact resistance, and are firmly connected to the cylinder barrel by welding/threading. The surface is treated with yellow anti-corrosion spray paint with strong adhesion and excellent weather resistance, which can effectively resist moisture, dust and corrosive media, extending the service life of the product. Built-in high-quality seal components, resistant to high pressure, oil and aging, can effectively prevent hydraulic oil leakage, ensuring stable system pressure and reducing maintenance frequency. The product has passed strict factory tests, including pressure resistance test, leakage test, load test, etc., to ensure that all performance indicators meet the original equipment standards. At present, this model of hydraulic cylinder is in stock, which can quickly respond to orders and provide stable supply guarantee, making it an ideal accessory for the maintenance and repair of construction machinery in mining, construction, water conservancy and other fields.
