Airtac SAIF Series Standard Cylinder with Valve SAIF63X75S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X75S-08A 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 SAIF63X75S-08A
The AirTAC SAIF63X75S-08A is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, featuring a built-in 4M310-08 5/2 solenoid valve. This integrated valve delivers a Cv of 1.40 and an effective orifice of 25.0 mm2, driving the 63mm bore to 1559N of push force at 0.5 MPa. Equipped with a -S magnet, it supports CMSE reed and DMSE electronic sensors for precise position feedback. The unit uses an AC220V terminal coil drawing 3.5 VA, protected to IP65 with a 0.05s response.
Because the manifold routes air directly via O10xO6.5 PU tubing, you eliminate remote plumbing and save panel space for decentralized machine stations. The cylinder body rates to 1.0 MPa, but the practical SAIF operating range is 0.15-0.8 MPa due to the valve's internal pilot limits. Factory-set to retract the rod when energised, the valve can be repositioned to extend on signal. The 5/2 design holds position by pilot pressure, not a spring, but does not lock the load without live air.

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)

| 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 SAIF63X75S-08A Is Used
Decentralized Automation
Ideal for large machines with multiple stations, eliminating long air lines by switching the actuator locally via the built-in valve.
Compact Clamping
Delivers 1559N push force at 0.5 MPa in a tight footprint, perfect for holding parts during machining or assembly.
Retrofit Upgrades
Simplifies machine upgrades where running new valve tubing is costly, requiring only an AC220V electrical signal.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X75S-08A the Right Choice?
Select this 63mm bore when a 50mm cylinder (982N push at 0.5 MPa) is too weak, but an 80mm unit (2513N) is physically oversized. The 75mm stroke is ideal for short clamps. Choose this self-valved SAIF over a separate cylinder and remote valve when decentralizing stations across a large machine, as one AC220V terminal signal controls the entire actuator. If your system needs to hold a load unpowered, select a SAIL lock cylinder instead, as the 5/2 valve and air cushions here only manage motion, not braking.
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 SAIF63X75S-08A FAQ
The 63mm bore generates 1559N push and 1402N pull force at 0.5 MPa. The built-in 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40) with a max frequency of 4 cycles/sec.
The AC220V terminal coil (3.5 VA, IP65) activates in 0.05s. By default, the factory setting retracts the rod when energised, but you can reposition the valve to extend-when-energised. This removes the need for a separate remote valve.
