Guoyue Hydraulics 200mm Bore 2310mm Stroke Heavy-Duty Single-Acting Plunger Hydraulic Cylinder — ISO 6020/6022, 250 Bar, Hard Chrome Plated

Specification: Industrial Multi-stage Telescopic Cylinder / MT4 Trunnion / High Force Density / Massive Bore Actuator 

Multi-stage Telescopic Engineering: Features a heavy-duty nested cylinder design that allows for an exceptionally long extension stroke while maintaining a very compact retracted length. Ideal for space-constrained industrial lifting.
Massive Force Output: Available in large-bore configurations (270mm/160mm), engineered to provide massive pushing and pulling force for heavy-duty tilting and material handling equipment.
MT4 Intermediate Trunnion Mounting: Equipped with precision-machined intermediate trunnion pins. This mounting style provides superior pivot stability and automatic alignment during the telescopic extension, significantly reducing lateral stress on stage seals.
Precision Surface Hardening: Each telescopic stage is precision-ground and induction hardened, followed by a 30-50μm Hard Chrome Plating (surface hardness HRC 55-60) to ensure minimum friction and maximum wear resistance.
Sealing & Reliability: Utilizes high-performance multi-lip sealing systems specifically designed for telescopic motion, ensuring zero internal leakage and pressure retention across all stages even under varying loads.
Heavy-Duty Construction: Constructed from high-tensile alloy steel to withstand peak pressures of up to 31.5 MPa and high-frequency industrial duty cycles.
Applications: Ideally suited for large-scale platform tilting mechanisms, heavy-duty specialized machinery, refuse collection vehicles, and mining equipment where a long-stroke/compact-footprint ratio is critical.
