Custom Double Acting Hydraulic Cylinder For Scissor Lift Aerial Work Platform Hard Chrome Piston Rod

Custom Double Acting Hydraulic Cylinder For Scissor Lift Aerial Work Platform Hard Chrome Piston Rod
Product description:

Our double acting hydraulic cylinders are specially engineered for scissor-type aerial work platforms. Adopting high-strength 27SiMn cylinder tube and 42CrMo solid piston rod with 50μm hard

chrome plating, the product features ultra-low friction, excellent wear resistance and zero internal drift under static load. Equipped with imported multi-stage sealing components and built-in

safety counterbalance valve, it prevents sudden platform sinking caused by pipe burst, fully complying with EN280 aerial work safety standards. We support custom bore, stroke, mounting lugs

and buffer structure, widely used on self-propelled and rough terrain scissor lifts for construction maintenance, warehouse handling and municipal engineering.

Structure and Working Principle

The hydraulic steering cylinder consists of a cylinder barrel, piston, piston rod, seals, end covers, and hydraulic ports. When pressurized oil enters one side of the cylinder, it pushes the piston and extends or retracts the piston rod. This linear movement is transmitted to the steering linkage or wheel assembly, changing the vehicle’s direction.

In modern hydraulic steering systems, the cylinder often works together with a steering control valve or orbitrol steering unit, enabling smooth, stable, and precise steering. Some systems use double-acting steering cylinders, which provide equal force and speed in both directions, ensuring consistent handling even under heavy loads or uneven terrain.

Materials and Manufacturing Process

The cylinder body is manufactured from high-strength alloy steel or seamless Precision steel tubes, honed and polished internally for superior sealing performance and low friction. The piston rod is hard chrome plated or QPQ nitrided to resist wear, corrosion, and impact.

All components are precisely machined using CNC equipment and assembled with advanced robotic welding and heat treatment processes to ensure strength, durability, and dimensional accuracy. The sealing system uses high-quality materials from brands such as Hallite, and Parker, providing long-lasting, leak-free operation.

Each steering cylinder is designed and manufactured under strict ISO, DIN, and CE standards, guaranteeing global quality compliance and performance reliability.

Applications:

The hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy. It is the core executive component in the hydraulic system. The hydraulic cylinder uses hydraulic oil to drive the piston to move, converting hydraulic energy into linear reciprocating motion. When the hydraulic oil enters the cylinder barrel, it pushes the piston rod to extend or retract, completing the predetermined action. The direction and speed of its movement are regulated by the hydraulic control system. The hydraulic cylinder consists of a cylinder barrel, cylinder cover, piston and piston rod, sealing device, and buffering device. According to its structure, it can be classified as piston type, plunger type, multi-stage telescopic sleeve type, and gear rack type. Hydraulic cylinders are widely used in machine tools, construction machinery, vehicles, and other fields, featuring a simple structure and smooth movement.

The hydraulic steering cylinder is an essential component in a wide range of mobile and industrial equipment, including:

• Agricultural tractors and harvesters – for stable, efficient field maneuvering.
• Wheel loaders and forklifts – to provide responsive steering under load.
• Construction machinery – such as graders, bulldozers, and excavators, for precise directional control.
• Heavy-duty trucks and trailers – for safe steering assistance and load balancing.
• Mining and off-road vehicles – for strong and reliable steering in rough environments.
• Marine and ship steering systems – to control rudders for accurate navigation.
• In all applications, steering cylinders deliver stable, smooth, and reliable performance, ensuring safe and efficient vehicle operation.
