Specification: Plunger Cylinder, Single-Acting, Heavy-Duty, ISO 6020, 25 MPa (hydraulic cylinder, plunger type cylinder, single acting cylinder, 200mm bore cylinder)
Linear reciprocating telescopic oil cylinder,Rotary swing telescopic oil cylinder,Sleeve type telescopic oil cylinder
Manufactured under ISO 6020/6022 dimensional standards with 200 mm plunger diameter and 2310 mm stroke. Barrel constructed from 27SiMn honed seamless steel tube, precision-bored and roller-burnished for surface roughness Ra ≤ 0.2 μm.
Plunger rod in 45# carbon steel, inductively hardened to HRC 50–55, then hard chrome plated to 30–50 μm thickness with HV 800–1000 surface hardness. Salt spray resistance exceeds 96 hours (ASTM B117).
Sealing system: multi-lip V-packing set in PU/NBR composite, paired with double-action dust wiper and polyurethane rod buffer ring. Static seals use O-ring + PTFE backup ring configuration. Leak-free under rated pressure cycling per ISO 10100.
Middle flange mounting (MF3 type) with 8-bolt hole pattern, CN machined from forged 45# steel. End cap secured via high-tensile 12.9 grade hex bolts, torqued to specification. Threaded rod end connection accepts standard metric fine thread inserts.
Compatible with Rexroth CD/CG series and Parker HMI series mounting footprints. Interchangeable with DIN 24333 / ISO 6020-1 flange-type cylinders for retrofit applications.
Test procedure: each unit undergoes 1.5× rated pressure hydrostatic test (37.5 MPa) for 5 minutes, followed by low-pressure (0.5 MPa) full-stroke cycling to verify seal integrity and smooth operation. Test certificate included.
Suitable for: hydraulic press (vertical/horizontal), plastic injection molding machine clamp circuit, steel mill roll gap adjustment, die-casting machine ejector, waste compactor, and general heavy-duty industrial push applications requiring high thrust in a compact retracted length.
