Airtac SAIF Series Standard Cylinder with Valve SAIF80X300S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF80X300S-08B 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-08B
The AirTAC SAIF80X300S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. Delivering a push force of 2513N at 0.5MPa and equipped with a -S magnet for CMSE reed and DMSE electronic sensors, it provides robust actuation. The manifold connects the valve to the cylinder using O10xO6.5 PU tubing, while the valve itself features a PT1/4 port. Driven by a DC24V terminal coil consuming 3.0W, it achieves a maximum switching frequency of 4 cycles per second with an IP65 rating.
Because the built-in valve operates at 0.15-0.8MPa, this defines the practical working pressure range for the assembled unit, even though the cylinder body rates up to 1.0MPa. By default, the factory setting retracts the piston rod when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. This self-contained design eliminates the need for a separate remote valve, significantly reducing tubing and panel space for decentralized machine stations.

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-08B Is Used
Decentralized Automation Stations
Ideal for large machines with multiple actuation points, eliminating long pneumatic tubing runs by mounting the valve directly on the cylinder.
High-Force Clamping Fixtures
Provides robust 2513N clamping force at 0.5MPa for machining and holding heavy workpieces securely in place.
Space-Constrained Machinery
Suits compact equipment layouts where external valve banks cannot fit, delivering reliable switching from a single DC24V signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF80X300S-08B the Right Choice?
Choose this 80mm bore when your application requires substantial thrust, such as the 2513N push force at 0.5MPa or 4523N at 0.9MPa. If your force requirements are lower, stepping down to a 63mm bore yields 1559N at 0.5MPa, whereas moving up to a 100mm bore provides 3927N at 0.5MPa. The integrated 4M310-08 valve offers an effective area of 25.0mm2 (Cv 1.40), ensuring adequate flow for the 80mm bore.
A self-valved SAIF is highly advantageous over a separate cylinder and remote valve when installation space is tight and running pneumatic tubing is costly or complex. This specific configuration uses a DC24V terminal connection and PT tapered threads. Note that the built-in 5/2 valve routes air and holds its last position via internal pilot pressure, but it does not lock the load mechanically; for secure position holding, consider the SAIL lock or BSAI clamp-lock series. Additionally, for this 300mm stroke length, ensure proper guide support to prevent excessive side-loading on the piston 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 SAIF80X300S-08B FAQ
At 0.5MPa, this 80mm bore double-acting cylinder provides a push force of 2513N and a pull force of 2268N. At 0.9MPa, the push force increases to 4523N.
No, it features a built-in 4M310-08 5/2 solenoid valve with a Cv of 1.40. By default, the rod retracts when the DC24V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
