Airtac SAIF Series Standard Cylinder with Valve SAIF80X160S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X160S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 160mm stroke and a built-in 4M310-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF80X160S-08A
The AirTAC SAIF80X160S-08A is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a 25.0 mm2 effective orifice. Driven by an AC220V terminal entry coil drawing 3.5 VA, it energizes in 0.05 s or less with IP65 protection. The integrated manifold uses O10 x O6.5 PU tubing to bridge the valve and cylinder, eliminating remote plumbing. This self-contained assembly operates within a practical 0.15-0.8 MPa range, as the valve limits the cylinder's 1.0 MPa rating.
Featuring a 80 mm bore and a carbon steel piston rod, this unit generates 2513 N of push force at 0.5 MPa. The factory setting retracts the rod when the coil is energized, but you can reposition the valve to extend on signal. The -S magnet option supports CMSE reed and DMSE electronic sensors for precise position feedback across the 160 mm stroke.

| 0.7 MPa | 3519 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF80X160S-08A Is Used
Decentralized Automation
Perfect for large factory layouts where installing a remote valve island is costly. The built-in 4M310 valve lets this 80 mm bore cylinder switch itself directly from a single AC220V signal.
High-Force Clamping
Delivers 2513 N of push force at 0.5 MPa for securing heavy workpieces. The integrated valve responds in 0.05 s, ensuring rapid clamping cycles on machining lines.
Retrofit & Upgrades
Ideal for upgrading existing ISO 15552 machinery. The PT threaded 3/8 inch cylinder port and terminal electrical entry simplify installation in space-tight cabinets.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X160S-08A the Right Choice?
Choose this 80 mm bore when an application requires substantial thrust, such as the 2513 N push force at 0.5 MPa, but a smaller 63 mm bore (1559 N at 0.5 MPa) would be insufficient. The integrated 4M310 valve makes the SAIF series ideal for decentralized stations where running separate valve tubing and wiring would consume excessive panel space. If your process requires true load holding without live air pressure, select a SAIL lock cylinder instead, as the 5/2 valve and air cushions here only route air and decelerate motion.
When ordering a replacement, verify the 160 mm stroke, 3/8 inch cylinder port, PT tapered threads, and the AC220V terminal coil configuration. The valve port code 08 specifies a 1/4 inch connection. For strokes of 160 mm or greater, ensure adequate guiding to prevent excessive side loading on the carbon steel rod.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF80X160S-08A FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. The built-in 4M310-08 5/2 valve provides an effective flow area of 25.0 mm2 with a Cv of 1.40.
No separate remote valve is needed. The integrated 4M310 valve switches the cylinder directly from one AC220V coil signal. By factory default, the piston rod retracts when the coil is energized, but this can be reconfigured to extend-when-energized by repositioning the valve.
