Airtac SAIF Series Standard Cylinder with Valve SAIF50X200S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X200S-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 200mm 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 SAIF50X200S-08A
The AirTAC SAIF50X200S-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific SKU is configured with a PT 1/4 cylinder port, a 1/4 inch valve port, and an AC220V terminal coil. The built-in valve offers an effective area of 16.0 mm2 (Cv 0.89) and switches at up to 5 cycles per second. Because the valve manifold mounts directly to the cylinder body using O8 x O5 PU tubing, you eliminate remote plumbing and save panel space. While the cylinder body itself is rated for 1.0 MPa, the integrated pilot valve operates at 0.15-0.8 MPa, making the practical working range for this assembled unit 0.15-0.8 MPa. The AC220V coil consumes 3.5 VA, features IP65 protection, and activates in 0.05 s or less.
This 50 mm bore version delivers 982 N of push force at 0.5 MPa and 1767 N at 0.9 MPa. Equipped with a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic sensors mounted in the dual-side sensor grooves. A key operational behavior is that the factory setting retracts the piston rod when the coil is energised; by repositioning the valve, you can reconfigure it to extend when energised. The unit relies on variable air cushions at both ends to decelerate the load near stroke end, but it does not hold position without live pressure.

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 (Ø50mm)

| 0.5 MPa | 982 N | 825 N |
| 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 SAIF50X200S-08A Is Used
Decentralized Assembly Stations
Ideal for large machines with multiple independent stations, eliminating the need to route tubing back to a central valve island.
Space-Constrained Automation
The integrated manifold block saves valuable panel space and reduces overall plumbing complexity on tight machine layouts.
Retrofit and Upgrades
Perfect for upgrading existing ISO 15552 cylinder setups where adding a remote valve would require extensive new tubing runs.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X200S-08A the Right Choice?
Choose this 50 mm bore SAIF model when your application requires 982 N of push force at 0.5 MPa. If you need less force, the 40 mm bore offers 628 N at 0.5 MPa; if you need more, the 63 mm bore provides 1559 N at 0.5 MPa. The self-valved SAIF design is optimal for decentralized stations on large machines where running separate valve tubing is costly, as it switches itself from one coil signal. For load-holding applications, note that the 5/2 valve routes air but does not lock the cylinder; you should consider the SAIL lock or BSAI clamp-lock series instead. This 200 mm stroke configuration is within standard limits and does not require non-standard sizing. When ordering a replacement, verify the 50 mm bore, 200 mm stroke, 1/4 inch valve port, AC220V 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 SAIF50X200S-08A FAQ
The 50 mm bore cylinder provides 982 N of push force and 825 N of pull force at 0.5 MPa. The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89) and a maximum frequency of 5 cycles per second.
Yes. The factory setting retracts the rod when the AC220V coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. This allows the single coil signal to control the cylinder without needing a separate remote valve.
