A heavy-duty ISO-standard pneumatic cylinder optimized for long-stroke industrial applications. Features corrosion-resistant construction with IP65 protection rating and optional grease pre-lubrication (VG68 oil equivalent). Requires 40μm filtered air with 1-10 mg/m³ oil mist lubrication for optimal performance.
- Automated material handling systems
- Injection molding machine ejectors
- Automotive assembly line clamping
- Paper processing equipment actuators
- Metal stamping press feeders
Installation guidelines:
Maintain 0.1-0.3 mm alignment tolerance during mounting. For vertical installations,
use counterbalance valves. Magnetic sensors require 12-24V DC power with ≤10mA current.
Relubricate every 2,000 km of cumulative travel distance.
