Ultra-slim profile cylinder engineered for precision linear motion in confined spaces. Features dual anti-rotation guides and a hex-shaped body for tool-free stroke adjustment (±1mm precision). The hard-anodized surface treatment provides enhanced wear resistance in dusty environments. Requires 5μm filtered air with ISO VG32 hydraulic oil mist lubrication (0.1–1.0 mg/m³).
- PCB handling robots in electronics manufacturing
- Micro-positioning stages in optical alignment systems
- Cartesian coordinate actuators for 3D printing
- Automated test equipment (ATE) fixture clamping
- Pharmaceutical blister packaging machines
Installation guidelines:
Maximum side load ≤15N. For vertical mounting, use tandem cylinders or counterbalance valves.
Lubricate every 500km of travel or 6 months (whichever comes first). Stroke adjustment requires
2.5mm hex key (included). Avoid exposure to cutting fluids containing chlorinated additives.
