Airtac SAIF Series Standard Cylinder with Valve SAIF100X200S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X200S-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 200mm 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 SAIF100X200S-08B
The AirTAC SAIF100X200S-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve, delivering a Cv of 1.40 and a robust 3927N push force at 0.5 MPa. It features a carbon steel piston rod and a -S magnet for precise position sensing using AirTAC CMSE reed or DMSE electronic switches. Because the manifold block mounts the valve directly using O10xO6.5 PU tubing, you drive the cylinder from one DC24V terminal coil signal without routing separate remote plumbing.
The cylinder body rates to 1.0 MPa, but the integrated internal-piloted valve operates at 0.15-0.8 MPa, setting the practical working range for this assembled SAIF unit. By factory default, the piston rod retracts when the coil is energised; you can reconfigure it to extend-when-energised simply by repositioning the valve. The 5/2 valve holds its last position via pilot pressure, not a spring, and the variable air cushions decelerate the rod near stroke ends.

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 SAIF100X200S-08B Is Used
Decentralized Automation
Ideal for large machines with decentralized stations, eliminating remote valve plumbing by driving the 100mm bore directly from the integrated 4M310 valve.
High-Force Clamping
Provides 3927N of push force at 0.5 MPa for heavy-duty clamping or pressing tasks where a separate valve would consume excessive panel space.
Retrofitting Air Systems
Suits machine retrofits where running new valve tubing is costly; a single DC24V electrical signal actuates the cylinder via the built-in manifold.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X200S-08B the Right Choice?
Choose this 100mm bore when you need high thrust that a 80mm bore cannot provide, stepping up from 2513N to 3927N push force at 0.5 MPa. A self-valved SAIF beats a separate cylinder and remote valve when panel space is tight or you are building decentralized stations across a large machine, eliminating long tubing runs. This model uses a DC24V terminal connection with a PT1/4 valve port and a PT1/2 cylinder port. For position feedback, pair the -S magnet with CMSE or DMSE sensors. If your application requires holding a load without live pressure, note that the 5/2 valve routes air but does not lock; select an AirTAC SAIL lock cylinder instead. To replace this unit, match the 100mm bore, 200mm stroke, 4M310-08 valve, DC24V voltage, terminal entry, PT thread, and -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 SAIF100X200S-08B FAQ
The 100mm bore generates 3927N push and 3681N 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 maximum frequency of 4 cycles per second.
The DC24V terminal coil draws 3.0W, features IP65 protection, and activates in 0.05s. By factory default, energising the coil retracts the rod, but you can reposition the valve to extend-when-energised. The 5/2 valve holds its position by pilot pressure, so no separate remote valve is needed.
