Description
1. ISO15552 (formerly ISO6431) Standard Cylinder Design
2. Features wear-resistant Y-shaped axial sealing structure with cushioning function, extended service life, and low friction resistance;
3. Aluminum square tube profile with anodized tie rods for superior corrosion resistance;
4. Built-in adjustable pneumatic cushioning at both ends;
5. Multiple cylinder specifications and mounting accessories available for flexible configurations.
Category: Standard Cylinders | Brand: AirTAC | Series: SI40
Installation guidelines:
Maintain 0.5-1mm alignment tolerance during mounting. For vertical installations exceeding 500mm stroke,
use rod-end support brackets (Order code: BR-40S). Lubricate through air port with ISO VG32 turbine oil
during initial commissioning.
