A heavy-duty adjustable stroke cylinder featuring precision-ground rod and dual-position locking mechanism. The micrometer-style stroke adjustment allows fine-tuning (±0.1mm resolution) via rotating end caps. Includes magnetic piston for sensor compatibility and anti-rotation guide to prevent axial twisting under load.
- Variable height positioning in automated assembly lines
- Clamping force adjustment in woodworking fixtures
- Material handling systems requiring stroke customization
- Press machines with depth control requirements
- Packaging equipment with product size variations
Installation notes:
- Use locknuts (M10×1.5) for secure foot mounting
- Lubricate with ISO VG32 hydraulic oil before initial operation
- Limit lateral load to ≤15% of maximum thrust capacity
- For stroke adjustment: Loosen lock screw, rotate end cap (1 full rotation = 2mm stroke change), then re-tighten
