- CNC machine tool door interlocks
- Printing press paper feed systems
- Packaging machine product ejection
- Plastic injection molding machine core pulls
Installation tip:
Align cylinder axis within 0.2mm perpendicularity tolerance to prevent side load.
Lubricate with ISO VG32 hydraulic oil if operating below -10℃.
Allow 5mm clearance behind rod end for full cushioning effect.
