Airtac SAIF Series Standard Cylinder with Valve SAIF63X150S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X150S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 150mm 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 SAIF63X150S-08A
The AirTAC SAIF63X150S-08A 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 area of 25.0 mm2 (Cv 1.40) and connects to the cylinder manifold via a PU tube (O10 x O6.5). Equipped with an AC220V terminal entry coil consuming 3.5 VA, it activates in 0.05 s with an IP65 rating. The -S magnet supports CMSE reed and DMSE electronic sensors for precise position detection.
While the cylinder body rates to 1.0 MPa, the integrated valve operates at 0.15-0.8 MPa, making the practical working range 0.15-0.8 MPa. At 0.5 MPa, this 63 mm bore generates 1559 N of push force and 1402 N of pull force. Factory set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised. By switching itself from one coil signal, it eliminates remote valves and tubing, saving panel space for decentralized installations.

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)

| 0.5 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 SAIF63X150S-08A Is Used
Decentralized Automation Stations
Ideal for large machines where mounting valves locally at each station saves wiring and pneumatic plumbing costs compared to centralized control panels.
Mid-Force Handling
Provides 1559 N of push force at 0.5 MPa for clamping, lifting, and pressing tasks that require moderate thrust and integrated 5/2 valve flow control.
Space-Constrained Retrofits
Suits machine upgrades where adding a separate valve island is physically impossible, leveraging the built-in 4M310 valve and manifold block.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X150S-08A the Right Choice?
Choose this self-valved SAIF unit when decentralized machine stations require localized control without running extensive pneumatic tubing back to a main manifold. Stepping down to a 50 mm bore drops the push force to 982 N at 0.5 MPa, while moving up to an 80 mm bore increases it to 2513 N. The integrated 4M310 valve offers a max frequency of 4 cycles/sec, making it suitable for moderate automation speeds.
For replacements, match the 63 mm bore, 150 mm stroke, 4M310-08 valve port, AC220V voltage, terminal entry, and PT thread. Note that the cylinder port is 3/8 while the valve port is 1/4. The air cushion decelerates the rod near stroke ends, but the 5/2 valve does not hold loads without live pressure; for true mechanical locking, consider the SAIL series. The carbon steel rod handles standard loads, but for any stroke over 300 mm, add external guides to prevent side-load wear.
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 SAIF63X150S-08A FAQ
The 63 mm bore generates 1559 N push and 1402 N pull force at 0.5 MPa. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) and a maximum frequency of 4 cycles/sec.
The AC220V terminal coil drives the 5/2 valve, which routes air to switch the cylinder. Factory set to retract when energised, it can be repositioned to extend. The valve does not hold loads unpressurized; for load holding, use the SAIL series.
