High-precision industrial cylinder featuring wear-resistant construction and precision honed tube. The SI40 series combines 20% increased lateral load capacity compared to previous generations, with enhanced corrosion resistance through multi-stage surface treatment. Requires 5-40μm filtered lubricated air (ISO 8573-1 class 4).
- Automated material handling systems
- Plastic injection molding ejectors
- Packaging machine clamping mechanisms
- Automotive assembly line tooling
- Food processing equipment (stainless steel version available)
Installation guidelines:
Allow minimum 0.5mm alignment tolerance during mounting. For vertical installations,
use rod-down position with speed control. Lubricate through air supply (ISO VG32
or equivalent) for optimal seal life. Maximum side load: 28N at full extension.
