Airtac SAIF Series Standard Cylinder with Valve SAIF100X900-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X900-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 900mm 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 SAIF100X900-08A
The AirTAC SAIF100X900-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve with a 1.40 Cv flow coefficient. Driven by an AC220V terminal coil consuming 3.5 VA, it eliminates the need for a remote valve bank, saving tubing and panel space across decentralized machine stations. The assembly operates within a 0.15-0.8 MPa pressure range, as the built-in valve limits the 1.0 MPa cylinder capacity, yielding a robust 3927N push force at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, but you can reconfigure the valve to extend-when-energised by repositioning it. The manifold connects to the cylinder using O10 x O6.5 PU tubing, and the 1/4" valve port is distinct from the 1/2" cylinder port. Responding in 0.05s with IP65 protection, this unit switches itself efficiently without requiring separate plumbing.

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 (Ø100mm)

| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAIF100X900-08A Is Used
Decentralized Automation
Ideal for large-scale machines with decentralized stations, using a single AC220V signal to drive the 3927N thrust without a remote valve bank.
Extended Stroke Handling
Suitable for long-travel 900mm actuation tasks, provided external guide supports are used to mitigate side loads on the 25mm carbon steel rod.
Space-Constrained Retrofits
Perfect for upgrading older lines where plumbing new air lines is difficult, as the built-in 4M310-08 valve manages switching directly at the cylinder.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X900-08A the Right Choice?
Choose this 100mm bore when you need maximum thrust; stepping down to an 80mm bore drops the 0.5 MPa push force to 2513N. The 900mm stroke is substantial, so ensure adequate guide support to manage side loads and prevent rod binding over extended travel distances. This self-valved SAIF assembly is ideal for decentralized installations where running separate valve tubing is costly or space-prohibitive.
When ordering a replacement, verify the 100mm bore, 900mm stroke, 1/2" cylinder port, 1/4" valve port, AC220V voltage, terminal entry, and PT tapered threads. Note that the 5/2 valve routes air and is not a lock; for position holding under zero pressure, consider the SAIL lock or BSAI clamp-lock cylinder variants.
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 SAIF100X900-08A FAQ
The 100mm bore cylinder generates a push force of 3927N at 0.5 MPa. The integrated 4M310-08 5/2 solenoid valve has an effective area of 25.0mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
The unit uses an AC220V terminal coil (3.5 VA, IP65, 0.05s response). By factory default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. This built-in 5/2 valve holds its position via internal pilot pressure, eliminating the need for a separate remote valve.
