Precision-engineered adjustable stroke cylinder featuring dual-position locking mechanism for mid-stroke positioning. The SAUJ40 series combines impact-resistant construction with micrometer-grade adjustment capability (via external screw mechanism). Integrated wear-resistant guide bushings ensure smooth operation under side load conditions. Requires ISO VG32 hydraulic oil or equivalent lubrication.
- Variable clamping force fixtures in CNC machining centers
- Precision paper feed mechanisms in printing equipment
- Adjustable stoppers for automotive assembly robots
- Position-adjustable ejectors in plastic injection molding
- Tension control systems in textile machinery
Installation guidelines:
Maintain 0.5mm minimum clearance between rod end and load during alignment.
For vertical mounting, install with rod facing downward to prevent seal wear.
Lubricate through air port using oil mist (1 drop/m³ airflow recommended).
Critical note:
Do NOT exceed 80% of maximum pressure when using mid-position locking function.
Allow 30-second stabilization after stroke adjustment before full-load operation.
