Airtac SAIF Series Standard Cylinder with Valve SAIF100X450S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X450S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 450mm 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 SAIF100X450S-08B
The AirTAC SAIF100X450S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. Equipped with a 1/4 valve port, this built-in valve provides an effective flow area of 25.0 mm2 (Cv 1.40) and operates at a maximum frequency of 4 cycles per second. Driven by a DC24V terminal connection coil consuming 3.0 W, it achieves a rapid 0.05s activation time within an IP65 rated enclosure. The cylinder itself features a 1/2 port, a carbon steel piston rod, and a -S magnet for precise position detection using AirTAC CMSE reed or DMSE electronic sensors.
Because the cylinder body rates to 1.0 MPa but the internal pilot valve operates from 0.15-0.8 MPa, the practical working pressure for this assembled unit is 0.15-0.8 MPa. Generating 3927N of push force at 0.5 MPa and reaching a maximum of 801 kgf at 1.0 MPa, it delivers substantial thrust. The manifold connects to the cylinder via PU tubing (O10 x O6.5). By default, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve.

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 SAIF100X450S-08B Is Used
Decentralized Automation Stations
Ideal for large-scale machinery where running individual valve tubing back to a central panel is costly. The integrated 4M310 valve allows this 100mm bore cylinder to switch itself locally via a single DC24V signal.
High-Force Clamping Fixtures
Delivers 3927N of push force at 0.5 MPa for securing heavy workpieces. The built-in valve and 450mm stroke provide extended reach and rapid actuation without external plumbing.
Space-Constrained Machinery
By mounting the 5/2 valve directly onto the profile cylinder via a manifold block, this unit saves valuable panel space and simplifies electrical wiring in tight equipment layouts.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X450S-08B the Right Choice?
Select this 100mm bore model when an application demands high thrust that smaller bores cannot provide; for context, dropping to an 80mm bore reduces your push force at 0.5 MPa to 2513N. The 450mm stroke provides extended travel, and because it exceeds 300mm, you should account for potential side-loading and utilize appropriate guide rails to prevent rod damage. Choosing this self-valved SAIF configuration eliminates the need for a separate remote valve, drastically reducing panel space, wiring complexity, and plumbing runs for decentralized machine stations.
When ordering a replacement, verify the 100mm bore, 450mm stroke, PT1/4 valve port, DC24V terminal coil voltage, PT thread type, and the -S magnet requirement. Remember that the 5/2 valve routes air and the end-of-stroke cushions only decelerate the piston; neither function mechanically holds a load. If your application requires true load-holding under zero pressure, consider the SAIL lock cylinder or BSAI clamp-lock series instead.
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 SAIF100X450S-08B FAQ
The 100mm bore cylinder generates a push force of 3927N at 0.5 MPa and a maximum of 801 kgf at 1.0 MPa. The integrated 4M310-08 valve has an effective area of 25.0 mm2 (Cv 1.40) and supports up to 4 cycles per second.
Yes. The factory default setting retracts the piston rod when the DC24V coil is energised, but you can reconfigure it to extend-when-energised by physically repositioning the 5/2 valve on the manifold block. This eliminates the need for a separate remote valve.
