The SI40X135N features a chromium-plated piston rod with hardened steel construction (HRC 45-50) for wear resistance. Its dual cushioning system reduces impact noise to ≤75dB(A) at 0.5MPa. The anodized aluminum barrel (surface hardness HV≥80) resists chemical corrosion, while the magnetic piston (30mT holding force) enables position sensing integration.
- High-speed packaging machinery (up to 3 cycles/sec)
- Automated assembly line clamping devices
- Conveyor sorting systems with position feedback
- Cleanroom-compatible material handling (with optional stainless steel version)
- Food processing equipment (NSF-compliant when using FDA-grade seals)
Installation guidance:
Lubricate with ISO VG32 hydraulic oil (air line lubricator recommended).
For vertical mounting, position rod end downward to prevent seal wear.
Allow 15mm clearance behind cushion adjustment screws for maintenance.
