Construction Standards
Alloy Steel Barrel
The 65mm bore barrel is machined from seamless alloy steel tube and honed to Ra 0.4–0.8 µm. This surface finish ensures the piston seal maintains consistent contact pressure across the full stroke, minimising internal bypass leakage across the cylinder’s service life.
Hard Chrome Piston Rod
The 40mm rod is hard chrome plated and ground to h6 dimensional tolerance. Chrome hardness exceeds 68 HRC, providing the wear and corrosion resistance required in forklift service environments — ranging from clean indoor warehouses to outdoor yards and cold stores with high humidity.
Composite Seal Package
Polyurethane piston seal, PTFE-backed rod seal, and nitrile rod wiper. The composite selection balances pressure retention, temperature range, and low friction. Seal kits are available separately for in-field gland rebuild without complete cylinder replacement.
Performance Advantages
Consistent seal contact from first stroke to end of service life.
Hard chrome resists warehouse abrasion, moisture, and cleaning chemical exposure.
Every cylinder tested to 1.5× working pressure before shipment.
Standard tooling gland access; seal kits supplied separately.
