High-precision industrial cylinder featuring dual anti-rotation guide rods and wear-resistant composite seals. The chrome-plated piston rod undergoes multi-stage polishing (Ra≤0.4μm) for smooth operation. Equipped with magnetic piston (SI40BX280S-M version available) for position sensing. Requires 1μm filtered air with 30-50mg/m³ oil mist lubrication.
- Automated material handling systems
- Plastic injection molding machine ejectors
- Textile machinery tension control
- Semiconductor wafer transfer mechanisms
- Stamping press feeding devices
- Automotive assembly line positioning
Installation recommendation:
Maintain 0.05-0.1mm alignment tolerance during mounting. For vertical installations,
use spring-return side downward. Apply silicone-free grease (ISO VG32 equivalent)
during maintenance intervals (every 2,000km stroke or 6 months).
