Product Description
Choosing a Three-Stage Telescopic Cylinder brings several operational and economic benefits:
Ideal for equipment with limited space.
Up to 3–4 times longer stroke compared to single-stage cylinders.
Designed for heavy lifting and high-pressure environments.
Chrome-plated rods and precision seals extend service life.
Available in both single-acting and double-acting configurations.
Advanced sealing systems reduce leakage risks.
Tailored bore sizes, stroke lengths, and mounting styles to fit specific equipment.
The Three-Stage Telescopic Cylinder is manufactured through a precise and controlled process:
Premium ST52, CK45, or alloy steels are used.
Seamless tubes undergo cold drawing and honing for smooth internal finish.
Chrome-plated rods are induction-hardened for corrosion and wear resistance.
Multiple telescopic stages are machined with precision to ensure smooth extension.
High-performance seals from brands such as Parker, Hallite, or NOK.
End caps and mounting features are welded and machined to specifications.
Cylinders undergo hydrostatic pressure tests to ensure strength and leak-free operation.
Powder coating, phosphating, or painting for enhanced durability.
Dimensional checks, hardness tests, and surface roughness validation.
The Three-Stage Telescopic Cylinder is widely applied in industries requiring compact yet long-stroke hydraulic power:
Dump trucks, tippers, and loaders.
Underground transport, drilling rigs, and rock breakers.
Trailers, harvesters, and sprayers.
Cranes, forklifts, and lifting platforms.
Garbage trucks, cargo lifts, and telescopic booms.
Press machines, automated systems, and marine equipment.
