Airtac SAIF Series Standard Cylinder with Valve SAIF80X300S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X300S-08A is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 300mm 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 SAIF80X300S-08A
The AirTAC SAIF80X300S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a PT1/4 valve port, an AC220V terminal coil connection drawing 3.5 VA, and a carbon steel piston rod. Because the manifold uses O10xO6.5 PU tubing to bridge the cylinder and valve, the valve port (1/4) is distinct from the cylinder port (3/8). The integrated valve delivers a 25.0 mm2 effective orifice (Cv 1.40) and switches up to 4 cycles per second.
While the bare cylinder body is rated for 1.5 MPa proof pressure, the practical operating range for the assembled SAIF unit is 0.15-0.8 MPa due to the internal pilot valve limits. It delivers 2513 N of push force at 0.5 MPa. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised if your machine logic requires it. This self-switching design eliminates remote plumbing, saving panel space across decentralized stations.

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 SAIF80X300S-08A Is Used
Decentralized Automation
Eliminates the need for long air tubing runs back to a central panel, driving the cylinder directly from a single AC220V signal on large machines.
High-Force Clamping
Provides 2513 N of push force at 0.5 MPa for securing heavy workpieces, with the built-in 4M310 valve ensuring rapid 4 Hz cycling.
Space-Constrained Retrofits
Ideal for upgrading older machines where routing new valve tubing is costly, fitting the manifold directly onto the ISO 15552 profile body.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X300S-08A the Right Choice?
Choose this 80mm bore when you need high thrust (2513 N push at 0.5 MPa) but want to avoid the tubing runs of a remote valve island. If your application requires less force, stepping down to a 63mm bore yields 1559 N push at 0.5 MPa; stepping up to 100mm provides 3927 N. At a 300mm stroke, guide rails are recommended to prevent excessive side-loading on the carbon steel rod. The included -S magnet enables position sensing with AirTAC CMSE (reed) or DMSE (electronic) switches.
This AC220V terminal-entry model is ideal for standard factory power grids, activating in under 0.05 s with IP65 protection. Remember that the 5/2 valve routes air but does not lock the load mechanically—use a SAIL lock cylinder if static holding is required. When ordering a replacement, verify the 80mm bore, 300mm stroke, PT1/4 valve port, AC220V coil, terminal entry, PT thread, and -S magnet.
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 SAIF80X300S-08A FAQ
The built-in 4M310-08 valve has a 25.0 mm2 orifice (Cv 1.40). The 80mm bore cylinder generates 2513 N push and 2268 N pull force at 0.5 MPa, with a maximum push of 4523 N at 0.9 MPa.
The factory default setting retracts the piston rod when the AC220V coil is energised. By repositioning the 5/2 valve on the manifold, you can reconfigure it to extend-when-energised. The valve holds position via pilot pressure, not a spring.
