Product Introduction
Products Description
The hydraulic piston rod is one of the most critical components in a hydraulic cylinder, directly influencing the efficiency, durability, and safety of the entire system. At Wuxi Shenlu Hydraulic Machine Parts Co., Ltd, we specialize in manufacturing high-precision hydraulic cylinder piston rods designed for heavy-duty applications. Each rod is crafted with advanced machining, heat treatment, and surface finishing processes to ensure maximum strength, smooth movement, and resistance to wear. Whether used with a hydraulic cylinder piston or other related parts, our piston rods guarantee stable performance and long service life.
Features & Advantages
High Strength & Durability – Manufactured from premium alloy steel (CK45, ST52, 42CrMo) for excellent tensile strength and impact resistance.
Precision Honing & Grinding – Advanced machining ensures smooth surface finish, reducing friction and improving sealing performance with the hydraulic cylinder piston.
Corrosion Resistance – Chrome plating, nickel plating, or ceramic coatings provide superior protection against rust and harsh working conditions.
Excellent Straightness & Roundness – Precision-controlled tolerance ensures reliable piston movement inside the hydraulic cylinder.
Extended Service Life – Reduces system wear and minimizes downtime in demanding environments.
Products Applications
Our hydraulic piston rods are widely used in:
Construction machinery (excavators, loaders, bulldozers)
Agricultural equipment (tractors, harvesters, sprayers)
Hydraulic presses and industrial automation systems
Marine and offshore equipment
Heavy lifting and material handling machinery
Wherever a hydraulic cylinder piston rod is needed, our products provide high performance and stability.
