Description
1. ISO15552 (formerly ISO6431) standard cylinder
2. Piston seal features a profiled bidirectional sealing structure with compact dimensions and integrated oil reservoir functionality;
3. Cross-reinforced aluminum barrel without tie rods ensures superior corrosion resistance. Precisely machined sensor mounting grooves enable tool-free installation;
4. Adjustable pneumatic cushioning provides smooth end-stroke deceleration;
5. Multiple cylinder configurations and mounting accessories available for versatile application requirements;
6. High-temperature resistant sealing materials accommodate operating temperatures from 0°C to 150°C.
Category: Standard Cylinders | Brand: AIRTAC | Series: SAI50
Installation guidelines:
Use floating joints to prevent side load forces. For horizontal mounting,
install rod support brackets when stroke exceeds 300mm. Lubricate with ISO VG32
hydraulic oil if not using pre-lubricated air supply.
