A space-saving cylinder with micrometer-style stroke adjustment (±10% of nominal stroke) through precision ground screws. Features anodized aluminum construction with chromium-plated piston rod for corrosion resistance. The integrated shock absorber minimizes end-impact noise (below 75dB). Requires ISO 8573-1:2010 Class 3 lubricated or non-lubricated air.
- Precision positioning in semiconductor handling robots
- Clamping mechanisms in CNC fixture systems
- Micro-adjustment applications in optical equipment assembly
- Packaging machine product ejection systems
- Medical device actuation requiring controlled soft-stop
Installation tips:
Apply thread lock (Loctite 243 recommended) on mounting screws.
For vertical mounting, install speed controller on lower port.
Maximum side load tolerance decreases by 30% when operated at temperatures above 60℃.
