High-load industrial cylinder designed for precision linear motion in heavy-duty applications. Features dual anti-rotation guides (integrated keyway) and 360° adjustable magnetic field sensors. The T-slot mounting surface allows modular integration with robotic arms or assembly lines. Requires ISO 8573-1:2010 Class 3-4-3 compressed air.
- Metal stamping press ejection systems
- Injection molding machine clamp mechanisms
- Automotive welding fixture positioning
- Paper roll handling in printing machinery
- Foundry equipment for die casting extraction
Installation note:
Lubricate with ISO VG32 hydraulic oil before initial use. Allow 0.5-1% stroke margin beyond
mechanical stops. For vertical mounting, install drip collar (accessory code: DC125) to
prevent lubricant migration. Alignment tolerance: ≤0.2mm/m.
- Relubrication: Every 500km of cumulative travel or 6 months
- Seal inspection: Annually under normal loads (quarterly for shock loads >8g)
- Rod surface cleaning: Weekly in high particulate environments
