High-precision adjustable stroke cylinder featuring dual-position mechanical stoppers for micro-adjustment (±2mm fine-tuning capability). The SAUJ series incorporates a wear-resistant guide bushing and multi-layered sealing system, achieving over 5,000 km cumulative travel life at 0.5 MPa. Includes magnetic piston version compatibility (add "-M" suffix for sensor-ready models).

Industrial Applications:
  • Variable height positioning in automotive welding jigs
  • Packaging line product ejection systems
  • Plastic injection molding machine core pullers
  • Semiconductor wafer handling robots
  • Press brake tooling adjustment mechanisms
Installation protocol: Lubricate with ISO VG32 hydraulic oil or equivalent before initial use. Maximum side load: 120N at mid-stroke. For vertical mounting, always install rod end downward to prevent seal wear.
Adjustment procedure:
  1. Loosen stopper lock nut (13mm wrench size)
  2. Rotate external stopper collar (0.5mm per graduation)
  3. Re-tighten nut to 15±2 N·m torque
  4. Perform 3-5 test cycles to verify positioning
