High-precision industrial cylinder with exceptional lateral load capacity, featuring dual-position mechanical stoppers for stroke adjustment (±5mm fine-tuning). The triple-sealed piston design ensures leak-free operation in dusty environments. Includes magnetic switch groove (2 pcs) for position sensing compatibility. Requires ISO VG32 hydraulic oil for buffer adjustment.
- Automated palletizing systems requiring variable stacking heights
- Plastic injection molding machine ejectors
- Large-format CNC router tool changers
- Automotive assembly line positioning fixtures
- Steel coil handling equipment
Installation tip:
Always align cylinder axis within 0.2mm perpendicularity tolerance. For vertical mounting,
use auxiliary support brackets when stroke exceeds 500mm. Lubricate rod weekly with ISO VG32 oil.
Critical note:
Maximum side load 180N / Moment tolerance 45N·m. Exceeding these values may cause
premature seal wear - use guide mechanisms for heavy offset loads.
