High-precision adjustable stroke cylinder featuring dual-position mechanical stoppers for mid-stroke positioning. The SAUJ40 series incorporates a wear-resistant rod seal system and anti-rotation guide bushings, making it ideal for applications requiring repeatable positioning accuracy. Includes built-in magnetic sensor slots (model variant dependent).
- Variable height work platforms in assembly lines
- Precision clamping fixtures for CNC machining centers
- Adjustable material stops in packaging machinery
- Position-controlled lifting arms in automotive jigs
- Variable extrusion length control in plastic molding
Operation tip:
For optimal performance, maintain lubrication with ISO VG32 hydraulic oil mist
and avoid lateral loading exceeding 30N. Stroke adjustment requires loosening
both end locknuts before repositioning the stopper collars.
