High-performance industrial cylinder designed for heavy-duty linear motion applications. Features precision-machined aluminum construction with corrosion-resistant coating and wear-indicator stripes. The magnetic piston version (SI125X540-M) enables position sensing compatibility. Requires regular lubrication (ISO VG32 hydraulic oil recommended).
- Press machine ejection systems
- Automotive assembly line clamping devices
- Foundry equipment material handling
- Packaging machinery pusher mechanisms
- Steel mill roller positioning systems
Installation note:
Maintain 0.5-1mm alignment tolerance during mounting. For vertical installations,
use locking nuts on piston rod threads. Allow 100mm clearance at stroke ends for
cushion adjustment access. Lubricate through air supply (oil mist 1-2 drops/m³).
