Airtac SAIF Series Standard Cylinder with Valve SAIF50X250S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X250S-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 250mm stroke and a built-in 4M210-06 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 SAIF50X250S-06B
The AirTAC SAIF50X250S-06A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-06 5/2 solenoid valve. This integrated manifold uses an O8 x O5 PU tube to bridge the valve and cylinder, eliminating the need for remote plumbing. The 4M210-06 valve provides an effective area of 14.0 mm2 (Cv 0.78) and handles up to 5 cycles per second. Equipped with a DC24V terminal entry coil consuming 3.0 W, it activates in 0.05 seconds or less with IP65 protection. Because the valve limits the system, the practical working pressure is 0.15-0.8 MPa, even though the bare cylinder rates to 1.0 MPa.
This model delivers 982 N of push force at 0.5 MPa and includes an -S magnet for CMSE reed and DMSE electronic sensors. By default, the piston rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. It is an ideal decentralized solution where one coil signal drives the cylinder directly, saving panel space and tubing.

| 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 SAIF50X250S-06B Is Used
Decentralized Machine Stations
Eliminates long air lines by placing the 4M210 valve directly at the cylinder, simplifying control across large automated setups.
Compact Assembly Automation
Saves panel space and wiring by driving the 982 N push force from a single DC24V terminal coil signal directly on the actuator.
Retrofit & Upgrades
Ideal for upgrading existing ISO 15552 lines where running new remote valve tubing is costly, offering a self-contained 5/2 switching solution.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X250S-06B the Right Choice?
Choose this 50mm bore SAIF when you need 982 N push force at 0.5 MPa. If your application requires less force, step down to the 40mm bore which provides 628 N push at 0.5 MPa; if you need more power, the 63mm bore offers 1559 N push at 0.5 MPa. The self-valved SAIF design beats a separate cylinder and remote valve setup by drastically reducing wiring and plumbing, making it perfect for decentralized stations across large machines. The 4M210-06 valve features a PT1/8 port and pairs with the cylinder's 1/4 port. Note that the 5/2 valve routes air but does not lock the load; for true position holding, consider the SAIL lock cylinder. With a 250mm stroke, ensure adequate guiding to prevent excessive side loading. Replacement requires matching the 50mm bore, 250mm stroke, 06 valve port, 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 SAIF50X250S-06B FAQ
The 50mm bore cylinder provides 982 N push and 825 N pull force at 0.5 MPa. The built-in 4M210-06 valve has a 14.0 mm2 orifice with a Cv of 0.78.
No remote valve is needed; the integrated 5/2 valve switches the cylinder directly from a DC24V signal. The valve routes air but does not lock the load pneumatically. By factory default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
