The SI125X350H industrial-grade cylinder features triple sealing technology with integrated shock absorption, designed for heavy-duty cycle operations. Its reinforced end caps and double-guide piston structure ensure precise linear motion under high lateral loads. Requires ISO 8573-1:2010 Class 3-4-3 compressed air (40μm filtration recommended).
- Automotive production line clamping/pressing systems
- Steel mill material handling actuators
- Injection molding machine ejectors
- Paper converting equipment
- Heavy-duty packaging machinery
Installation tip:
Allow 50mm clearance at stroke ends for cushion adjustment.
Use M20x1.5 mounting screws (Grade 8.8 or higher) and align within
0.2mm/m perpendicularity tolerance. Lubricate with ISO VG32 turbine oil
if operating below 1 Hz cycle rate.
