Fatigue Testing Machine Hydraulic Cylinder

The Fatigue Testing Machine Hydraulic Cylinder is manufactured for precision industrial automation, machine tool, and test equipment applications where repeatability, low friction, and dynamic response are priorities. Low-friction composite bearing materials and precision-honed bore provide smooth, consistent performance over high-cycle duty schedules. Materials: barrel — seamless honed steel tube; piston rod — 45# or 40Cr alloy steel, induction hardened Ø0.03-0.05mm oversize then hard chrome plated to Ra≤0.4μm; seals — Parker (USA) or Merkel (Germany) standard. All cylinders are hydraulically pressure-tested before dispatch. Custom bore, stroke, mounting, port position and surface treatment available on request.
