Airtac SAIF Series Standard Cylinder with Valve SAIF63X500S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X500S-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 500mm 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 SAIF63X500S-08A
The AirTAC SAIF63X500S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. Driven by an AC220V terminal coil drawing 3.5 VA, it delivers a Cv of 1.40 and generates 1559N of push force at 0.5 MPa. The cylinder body rates to 1.0 MPa, but because the built-in valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. The carbon steel rod and integrated magnet for CMSE and DMSE sensors make it highly versatile.
By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design eliminates the need for a separate remote valve, saving panel space and making it ideal for decentralized stations across large machines. The manifold connects to the cylinder via PU tubing (O10 x O6.5), while the valve port is 1/4" and the cylinder port is 3/8".

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 SAIF63X500S-08A Is Used
Decentralized Automation
Perfect for large machines with multiple stations, eliminating long tubing runs by mounting the valve directly on the cylinder.
Material Handling
Provides robust 1559N push force for diverting or lifting packages on tight conveyor lines where panel space is limited.
Machining Clamps
Ideal for actuating clamps in tight machine cells, offering a 4M310-08 valve with a 1.40 Cv for rapid actuation.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X500S-08A the Right Choice?
Choose this 63mm bore when you need more thrust than a 50mm cylinder (which provides 982N push at 0.5 MPa), but want to avoid the larger envelope of an 80mm unit (2513N push at 0.5 MPa). A self-valved SAIF beats a separate cylinder and remote valve when wiring and pneumatic plumbing space is tight, as it switches itself from one AC220V coil signal. For position feedback, the -S magnet works with AirTAC CMSE reed and DMSE electronic solid-state switches.
At 500mm stroke, this cylinder is susceptible to side loads, so ensure proper guiding to prevent rod damage. Remember that the 5/2 valve routes air and the cushions only decelerate near stroke end; this unit does not hold the load without live pressure. For load-holding applications, consider an AirTAC SAIL lock cylinder. Replacement requires matching the 63mm bore, 500mm stroke, 1/4" valve port, AC220V voltage, terminal entry, PT thread, and the -S magnet.
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 SAIF63X500S-08A FAQ
At 0.5 MPa, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. At 0.7 MPa, the push force increases to 2182N.
No, the integrated 4M310-08 5/2 valve switches the cylinder directly from an AC220V terminal coil signal. The factory setting retracts the rod when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
