Product Details

Key Product Features
High-strength construction: Built from robust alloy materials (e.g., 45 steel, 304 stainless steel) to withstand extreme hydraulic pressures in heavy-duty engineering/industrial operations.
Precision-machined: Tight-tolerance fabrication (coaxiality ≤ 0.02 mm; mating surface roughness Ra ≤ 0.8 μm) ensures a seamless fit with cylinder barrels and piston rods, eliminating misalignment or abrasion risks.
Wear & corrosion resistant: Hard chrome-plated/passivated surface treatment enhances durability, resisting wear from piston rod reciprocation and corrosion in harsh working environments.
Sealing & dust-proof ready: Pre-machined grooves accommodate compatible seals (Y-rings, dust seals) to prevent high-pressure oil leakage and block external debris (dust, moisture).

Application Scenarios
Construction Equipment: Hydraulic cylinders for excavators, loaders, cranes
Industrial Hydraulics: Precision cylinders for injection molding machines, bending machines, hydraulic presses
Mining Machinery: Heavy-duty hydraulic cylinders for roadheaders, shearers
Marine Field: Corrosion-resistant cylinders for marine steering gears, windlasses

Note: Sold separately as a standalone maintenance component.
