Airtac SAIF Series Standard Cylinder with Valve SAIF80X80-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X80-08B is a genuine double-acting ISO 15552 cylinder with a Ø80mm bore, 80mm 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 SAIF80X80-08B
The AirTAC SAIF80X80-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve provides an effective flow rate of 25.0 mm2 (Cv 1.40) and operates at a maximum frequency of 4 cycles per second. Equipped with a DC24V terminal electrical entry consuming 3.0 W, it achieves IP65 protection and a rapid 0.05 s activation time. While the cylinder body is rated for 1.0 MPa, the practical operating range for the assembled SAIF unit is 0.15-0.8 MPa due to the internal pilot valve limits.
By utilizing a manifold block and O10 x O6.5 PU tubing, the valve directly controls the cylinder without needing a separate remote valve. This decentralized approach minimizes panel space and plumbing, requiring only a single coil signal to drive the motion. The factory setting retracts the piston rod when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve. Delivering a push force of 2513 N at 0.5 MPa, it handles heavy loads while the variable air cushions decelerate the rod near stroke ends.

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 SAIF80X80-08B Is Used
Decentralized Automation
Perfect for large factory layouts where installing a central valve bank is inefficient. The built-in 4M310 valve allows the SAIF80X80-08B to operate independently from a single DC24V signal.
Heavy Duty Clamping
Provides 2513 N of push force at 0.5 MPa for securing heavy workpieces during machining, utilizing its self-contained valve system to save valuable floor space.
Machine Retrofitting
Ideal for upgrading older equipment where routing new pneumatic tubing to a remote valve is difficult. The terminal entry and integrated valve simplify electrical and air connections.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X80-08B the Right Choice?
Select this 80mm bore model when your application requires high thrust, such as the 2513 N push force at 0.5 MPa, but you want to avoid the tubing complexity of a remote valve bank. If your force requirements are lower, stepping down to a 63mm bore provides 1559 N of push force at 0.5 MPa and uses the same 4M310 valve series. Conversely, moving to a 100mm bore yields 3927 N of push force at 0.5 MPa. The SAIF80X80-08B is ideal for space-tight machines where running valve tubing is costly or impractical.
Remember that the 5/2 valve routes air but does not mechanically lock the load; if power or air pressure drops, the cylinder will not hold its position. For applications requiring true load-holding, consider the SAIL (lock) or BSAI (clamp-lock) series. When ordering a replacement, verify the 80mm bore, 80mm stroke, PT1/4 cylinder port, 1/4 inch valve port (code 08), DC24V voltage, terminal entry, PT thread type, and standard carbon steel rod. No magnet is specified, so CMSE or DMSE sensors cannot be used without adding the -S option.
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 SAIF80X80-08B FAQ
The 80mm bore generates a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. The built-in 4M310-08 5/2 solenoid valve has an effective area of 25.0 mm2 (Cv 1.40) and supports a maximum frequency of 4 cycles per second.
No, the 5/2 valve is a directional control valve, not a locking mechanism. It routes air to the cylinder but cannot hold a load without live pressure. By default, the rod retracts when the DC24V coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
