The SI50X27 features a space-saving design with dual cushioning adjustment for smooth end-of-stroke deceleration. Its anodized barrel resists corrosion in humid environments, while the chrome-plated piston rod ensures low friction operation. Integrated magnet in piston enables position feedback when used with magnetic sensors (sold separately). Requires 40μm filtered air and ISO VG32 hydraulic oil if relubricated.

Installation note:
Align cylinder axis with movement direction within ±2° angular tolerance.
For vertical mounting, use locking nuts on rod threads to prevent
unscrewing under vibration. Allow 5mm clearance around barrel for heat dissipation.
