The SI80AX425S industrial cylinder features a rugged construction with precision honed inner bore (Ra≤0.2μm surface finish) for smooth operation. Its dual-piston design reduces lateral load on bearings, while built-in magnet slots enable position feedback via magnetic sensors. The chrome-plated piston rod includes a scraper seal to prevent contamination ingress.

Installation note:
Lubricate with ISO VG32 hydraulic oil before initial use.
Maintain 0.3mm minimum clearance between magnetic sensor and cylinder body.
For vertical mounting, install lock nuts to prevent piston rod rotation.
