The Double Acting Plunger Cylinder is a robust hydraulic cylinder designed to deliver linear force in both extension and retraction strokes. Unlike single-acting plunger cylinders, the Double Acting Plunger Cylinder uses hydraulic pressure alternately on both sides of the plunger rod, providing controlled bidirectional motion. This feature makes it highly suitable for applications that require frequent pushing and pulling under heavy loads.
Manufactured from seamless honed tubes and chrome-plated rods, the Double Acting Plunger Cylinder provides excellent wear resistance, high strength, and extended service life. Its simple yet durable design reduces the risk of failure and minimizes maintenance downtime, making it a preferred choice for distributors, stockists, and engineering contractors in industries such as construction machinery, hydraulic presses, marine equipment, and material handling systems.

Product Description
The Double Acting Plunger Cylinder offers numerous benefits compared to single-acting or piston-type cylinders:
Provides power in both directions, improving efficiency.
Built with high-quality steel, honed tubes, and chrome-plated rods.
Withstands heavy-duty vertical and horizontal loads.
Precision honing ensures excellent sealing and low friction.
Fewer components minimize wear and breakdown risk.
Hard chrome plating protects against rust and abrasion.
Available in multiple bore sizes, strokes, and mountings.
Optimized design reduces hydraulic power loss.
The Double Acting Plunger Cylinder is manufactured under strict quality control standards. The production steps include:
High-grade steels such as ST52, CK45, 42CrMo, or 20MnV6.
Seamless tubes are honed to Ra ≤ 0.2 μm for superior sealing.
Plunger rods undergo machining, induction hardening, and chrome plating.
CNC machining ensures accurate dimensions and tolerances.
End caps, seals, and rods are assembled to ensure structural integrity.
Premium sealing systems (Parker, Hallite, NOK) prevent leakage.
Every cylinder is tested at 1.5 times its rated working pressure.
Painting, phosphating, or powder coating for corrosion resistance.
Dimensional checks, hardness tests, and surface finish evaluations.
The Double Acting Plunger Cylinder is widely used across various industries due to its high performance and bidirectional force capability:
Excavators, loaders, concrete machinery, and lifting platforms.
Elevators, hoists, and hydraulic lift systems.
Metal forming, stamping, forging, and injection molding machines.
Ship deck machinery, offshore platforms, and lifting devices.
Tractors, harvesters, and tipping systems.
Heavy-duty lifting and pushing in underground and surface operations.
Assembly lines, compacting machines, and automation systems.
