High-rigidity twin rod cylinder with mechanical stopper adjustment system, featuring dual piston rods that eliminate rotational torque for precise linear motion. The symmetrical design ensures balanced load distribution, with corrosion-resistant construction suitable for harsh environments. Requires ISO 8573-1:2010 Class 3-4-3 compressed air.
- Precision press-fit operations in automotive assembly
- Vertical lifting mechanisms for glass handling systems
- Position-locked clamping in CNC machining centers
- Synchronized actuation in packaging line diverters
- Automated welding fixture positioning

1. Use locknuts (M12×1.25) on both adjustment screws after stroke setting
2. Lubricate with ISO VG32 hydraulic oil if used in low-speed applications (<50mm/s)
3. Maximum side load capacity: 300N at mid-stroke position
4. For vertical mounting, install rod supports at both ends
