Airtac SAIF Series Standard Cylinder with Valve SAIF50X50S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X50S-08B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 50mm 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 SAIF50X50S-08B
The AirTAC SAIF50X50S-08B is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89. It features a 50mm bore, 50mm stroke, and a carbon steel piston rod. Driven by a DC24V terminal coil consuming 3.0W, it integrates AirTAC CMSE and DMSE sensors via the -S magnet. The cylinder body rates to 1.0 MPa, but the integrated valve limits the practical operating pressure to 0.15-0.8 MPa.
This unit switches itself from a single coil signal, eliminating remote valve plumbing and saving panel space for decentralized stations. The manifold connects to the cylinder via O8xO5 PU tubing. Factory-set to retract the rod when energised, the valve can be repositioned to extend-when-energised. At 0.5 MPa, it provides 982N push and 825N pull force.

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 SAIF50X50S-08B Is Used
Decentralized Assembly Stations
Eliminates the need for a remote valve bank, reducing tubing runs and simplifying maintenance across large factory layouts.
Compact Clamping Fixtures
Provides 982N of push force at 0.5 MPa in tight spaces where mounting a separate valve is physically impossible.
Retrofit Automation Upgrades
Drops directly into existing ISO 15552 mounting interfaces while bringing self-switching DC24V control to older machines.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X50S-08B the Right Choice?
Choose this 50mm bore when you need 982N push force at 0.5 MPa; step down to a 40mm bore for 628N, or up to a 63mm bore for 1559N. A self-valved SAIF beats a separate cylinder plus remote valve in space-tight machines by cutting tubing and wiring. Select this DC24V terminal entry configuration for standard control panels. Ensure your stroke and load match the 30-800 mm/s speed range.
For replacements, match the 50mm bore, 50mm stroke, PT1/4 cylinder port, 4M210-08 valve port, DC24V voltage, terminal entry, and -S magnet. The 5/2 valve routes air but does not lock the load; use SAIL for load-holding. The air cushion only decelerates near stroke end.
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 SAIF50X50S-08B FAQ
The 50mm bore generates 982N push and 825N pull force at 0.5 MPa. The built-in 4M210-08 valve has a 16.0 mm2 orifice and a Cv of 0.89, allowing a max frequency of 5 cycles/sec.
No, it has an integrated 5/2 valve driven by a DC24V coil. It is factory-set to retract when energised but can be reconfigured to extend-when-energised by repositioning the valve.
