High-precision industrial cylinder featuring chromium-plated piston rod and aluminum alloy barrel with hard anodized finish. Optimized for heavy-duty cycling (500km+ service life) through triple-lip wiper seals and dual cushioning system. Includes auto-adjusting cushion needles that compensate for wear. Requires ISO VG32 hydraulic oil mist lubrication (0.1cm³/min minimum).
- Press machine ejection systems (200-300 cycles/min)
- Automated assembly line clamping fixtures
- Palletizing robot end-effector drives
- Plastic injection molding machine core pulls
- CNC tool changer mechanisms
Installation guidelines:
Align cylinder axis within ±0.5° angular misalignment. For horizontal mounting,
use rod support brackets when stroke/rod ratio exceeds 20:1. Lubricate through
air supply (FRL unit) at 1 drop/min oil feed rate.
