Product Description
The Single Rod Plunger Cylinder offers unique advantages that make it one of the most widely applied hydraulic cylinders in industrial and construction equipment:
Fewer components reduce failure risk and simplify maintenance.
Capable of supporting vertical loads in heavy-duty lifting applications.
Chrome-plated rods ensure resistance to corrosion and abrasion.
Lower production and maintenance costs compared to piston cylinders.
Ideal for limited-space applications requiring strong linear force.
Available in different diameters, strokes, and mounting styles.
Advanced sealing systems minimize hydraulic fluid leakage.
Optimized surface finish ensures smooth operation and reduced wear.
The Single Rod Plunger Cylinder is produced through a precise and standardized manufacturing process to ensure performance and durability:
Material Selection
High-grade steels such as ST52, CK45, or 42CrMo4 are used.
Tube Processing
Cylinder barrels are honed to Ra ≤ 0.2 μm for optimal sealing.
Rod Processing
Plunger rods are machined, induction-hardened, and chrome-plated.
Machining & Turning
CNC machining ensures accurate dimensions and tolerances.
Welding & End Fittings
Structural welding guarantees high mechanical strength.
Seal Installation
Imported seals (Parker, Hallite, NOK) provide durability and leak protection.
Hydraulic Testing
Each cylinder is tested under rated and overload pressures.
Surface Treatment
Painting, phosphating, or powder coating enhances corrosion resistance.
Final Inspection
Dimensional, surface roughness, and hardness checks are performed before delivery.
The Single Rod Plunger Cylinder is widely applied in industries requiring vertical lifting, strong pushing force, and compact structure:
Lifting equipment, scaffolding, and concrete machinery.
Steel mills, smelting equipment, and foundries.
Forging presses, stamping machines, and metal forming equipment.
Lifting platforms, elevators, and hydraulic lifts.
Loaders, sprayers, and tipping mechanisms.
Underground lifting systems and heavy-duty mining machinery.
Ship lifting devices and offshore platforms.
