Airtac SAIF Series Standard Cylinder with Valve SAIF50X600S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X600S-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 600mm 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 SAIF50X600S-08A
The AirTAC SAIF50X600S-08A is a double-acting profile cylinder dimensionally interchangeable per ISO 15552, paired with a built-in 4M210-08 5/2 solenoid valve. This integrated valve delivers a 16.0 mm2 flow (Cv 0.89) and operates at 5 cycles per second. Driven by an AC220V terminal entry coil drawing 3.5 VA, it activates in 0.05 s or less. The cylinder body features a 1/4" port, while the valve manifold connects via an O8 x O5 PU tube.
While the cylinder body rates to 1.0 MPa, the practical operating range for this valved assembly is 0.15-0.8 MPa. It delivers 982 N of push thrust at 0.5 MPa. Factory-set to retract the rod when energised, the valve can be repositioned to extend on signal. The -S magnet supports CMSE reed and DMSE electronic sensors for position feedback.

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)
| Pressure | Push force | Pull force |
|---|---|---|
| 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 SAIF50X600S-08A Is Used
Decentralized Stations
Ideal for large machines with distributed stations, eliminating long tubing runs by switching the 600 mm stroke locally from a single AC220V signal.
Material Handling
Provides 982 N of push force at 0.5 MPa for diverting or lifting products, with the built-in 4M210 valve handling rapid 5 cycle/sec actuation.
Space-Tight Machines
Fits compact envelopes where a separate remote valve manifold would be too bulky, using the integrated PT1/4 cylinder port and O8 x O5 PU manifold tube.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X600S-08A the Right Choice?
Choose this 50 mm bore when you need 982 N push force at 0.5 MPa; stepping down to a 40 mm bore drops thrust to 628 N, while an 80 mm bore yields 2513 N. A self-valved SAIF excels in decentralized stations by eliminating remote valve plumbing and panel space, switching directly from one AC220V terminal signal. For load-holding requirements, note that the 5/2 valve routes air but does not lock the piston; consider a SAIL lock cylinder instead.
At a 600 mm stroke, the standard carbon steel rod is susceptible to side loads, so guide rails should support the payload to prevent binding. This unit includes a magnet for CMSE/DMSE switches, uses PT tapered threads, and requires a replacement matching bore 50, stroke 600, valve port 08, AC220V, terminal entry, and the -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 SAIF50X600S-08A FAQ
At 0.5 MPa, the 50 mm bore provides 982 N push and 825 N pull thrust. The built-in 4M210-08 5/2 valve has an effective area of 16.0 mm2 (Cv 0.89).
No, the integrated 4M210 valve switches the cylinder directly from the AC220V terminal coil. It is factory-set to retract when energised but can be repositioned to extend when energised.
