Airtac SAIF Series Standard Cylinder with Valve SAIF50X1000S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X1000S-08B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 1000mm stroke and a built-in 4M210-08 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 SAIF50X1000S-08B
The AirTAC SAIF50X1000S-08B is a double-acting ISO 15552 profile cylinder equipped with a built-in 4M210-08 5/2 solenoid valve, offering a Cv of 0.89 and a 16.0 mm2 effective area. Driven by a DC24V terminal connection coil drawing 3.0 W, it features IP65 protection and a rapid 0.05 s activation time. The integrated manifold uses O8 x O5 PU tubing to bridge the valve and cylinder ports. Because the cylinder body rates to 1.0 MPa but the 4M210 internal pilot valve operates at 0.15-0.8 MPa, the practical working pressure for this assembled SAIF unit is 0.15-0.8 MPa. This 50 mm bore generates 982 N of push force and 825 N of pull force at 0.5 MPa.
By incorporating the valve directly on the profile barrel, this model eliminates the need for a separate remote valve, reducing tubing and panel space for decentralized machine stations. 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 -S magnet option supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection.

| 0.7 MPa | 1374 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 SAIF50X1000S-08B Is Used
Decentralized Processing Stations
Eliminates remote valve banks on large machines by driving the 50 mm bore locally from a single DC24V terminal signal, drastically cutting tubing complexity.
Long-Stroke Diverting
Provides reliable 1000 mm travel for sorting gates, where the built-in 4M210-08 valve and CMSE/DMSE sensors ensure consistent positioning without separate plumbing.
Space-Constrained Retrofitting
Drops directly into tight existing layouts where adding external pneumatic valves is impossible, leveraging the ISO 15552 mounting interface for easy swaps.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X1000S-08B the Right Choice?
Select this 50 mm bore when an application requires around 982 N push force at 0.5 MPa; if you need less force, step down to the 40 mm bore (628 N push at 0.5 MPa), or move up to the 63 mm bore (1559 N push at 0.5 MPa) for heavier loads. A self-valved SAIF is ideal when running separate valve tubing is costly or space-prohibitive, allowing one DC24V coil signal to control the actuator locally. Remember that the built-in 5/2 valve routes air but does not lock the load; for true position holding under pressure loss, consider the SAIL lock or BSAI clamp-lock series. For replacement, verify the 50 mm bore, 1000 mm stroke, PT1/4 cylinder port, 08 (1/4) valve port, DC24V voltage, terminal entry, PT thread, and -S magnet. Because the 1000 mm stroke is long, always use a guide rail to prevent rod sag and side-load damage.
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 SAIF50X1000S-08B FAQ
The 50 mm bore outputs 982 N push and 825 N pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve provides a 16.0 mm2 effective area (Cv 0.89) with a max frequency of 5 cycles/sec.
No, the integrated 4M210 valve controls the cylinder directly from a DC24V signal. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The valve operates at 0.15-0.8 MPa.
