High-precision adjustable stroke cylinder featuring dual-position memory capability through its mechanical locking system. The SAUJ40X850-30S combines 0.1mm repeat positioning accuracy with IP67 environmental protection, making it ideal for variable-position applications requiring mid-stroke stops. Integrated wear indicators on the cushion screws enable predictive maintenance planning.
- Variable-height material handling platforms
- Plastic injection molding ejector systems
- Automated welding positioners with multiple weld points
- Printing press paper feed mechanisms
- Semiconductor wafer handling robots
Operational guidance:
Lubricate with ISO VG32 hydraulic oil mist lubrication (1-2 drops/m³ air).
Avoid side load exceeding 30N. For vertical installations exceeding 45° angle,
use rod-end support brackets (sold separately). Maximum cycle rate: 200 strokes/min.
