Description
1. ISO15552 (formerly ISO6431) Standard Pneumatic Cylinder
2. Piston features bidirectional Y-seal structure with cushioning function, offering extended service life and low friction resistance;
3. Aluminum barrel with cruciform reinforcement and black-anodized piston rod for enhanced corrosion resistance;
4. Precision machined cylinder surface ensures smooth operation;
5. Multiple cylinder specifications and mounting accessories available for flexible configurations.
Category: Standard Cylinders | Brand: AIRTAC | Series: SI125
Installation tip:
Allow 10mm clearance around cylinder body for heat dissipation.
Lubricate through air ports using ISO VG32 turbine oil before initial
operation. Avoid side load exceeding 30N at rod end.
Maintenance note:
Replace wiper seals every 500,000 cycles in dusty environments.
Check cushion adjustment monthly in high-speed applications (>0.5m/s).
