Airtac SAIF Series Standard Cylinder with Valve SAIF63X75-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X75-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 75mm 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 SAIF63X75-08B
The AirTAC SAIF63X75-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve. This specific configuration uses a DC24V terminal electrical entry drawing 3.0W, protected to IP65 with a 0.05s response time. The integrated valve provides a Cv of 1.40 and routes air through a PU tube (O10 x O6.5) to the 3/8 cylinder port. While the cylinder body rates to 1.0 MPa, the practical operating range is 0.15-0.8 MPa due to the valve limits.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This self-switching design eliminates the need for a separate remote valve, drastically reducing panel space and plumbing. In this 63mm bore class, it delivers 1559N push force at 0.5MPa, making it ideal for decentralized stations across large machines.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 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 SAIF63X75-08B Is Used
Decentralized Machine Stations
Ideal for large machines where running individual valve tubing is costly, this self-valved cylinder operates independently from a single DC24V signal.
Mid-Force Clamping
Provides 1559N of push force at 0.5MPa for securing medium-weight workpieces during machining or assembly processes.
Space-Constrained Retrofitting
The integrated manifold block saves valuable panel space and simplifies wiring when upgrading existing pneumatic setups.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X75-08B the Right Choice?
Choose this 63mm bore if you need higher force than the 50mm option (982N push at 0.5MPa), but want to avoid the larger envelope of the 80mm class (2513N). The integrated 4M310-08 valve handles the flow for a 75mm stroke efficiently, making it superior to running a separate cylinder and remote valve when installation space and wiring complexity are concerns. For load-holding applications, note that the 5/2 valve routes air but does not lock the piston; consider the SAIL series for positive mechanical locking.
When replacing this unit, verify the 63mm bore, 75mm stroke, 08 (1/4) valve port, DC24V terminal coil, PT thread, and standard carbon steel rod. Because the stroke is under 300mm, standard mounting options like FA, FB, and TC apply without needing auxiliary side-load guides. No magnet is specified for this SKU, so position sensing via CMSE or DMSE switches is not supported without modification.
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 SAIF63X75-08B FAQ
The 63mm bore generates 1559N push and 1402N pull force at 0.5MPa. The built-in 4M310-08 5/2 valve has an effective area of 25.0mm2 (Cv 1.40) and a max frequency of 4 cycles/sec.
The integrated 5/2 valve holds position via internal pilot pressure, not a spring. The factory default setting retracts the rod when the DC24V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
