Airtac SAIF Series Standard Cylinder with Valve SAIF32X200-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X200-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm 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 SAIF32X200-08B
The AirTAC SAIF32X200-08B is a double-acting profile cylinder with an ISO 15552 mounting interface, featuring a built-in 4M210-08 5/2 solenoid valve that delivers a Cv of 0.89. Driven by a DC24V terminal entry coil consuming 3.0 W, it responds in 0.05s with IP65 protection. The integrated valve manifold connects via an O8xO5 PU tube to the 1/8 cylinder port, meaning the 1/4 valve port and cylinder port are distinct. While the bare cylinder rates to 1.0 MPa, the practical SAIF operating range is 0.15-0.8 MPa, matching the valve's internal pilot limits.
In the 32mm bore class, this self-switching unit generates 402N of push force and 345N of pull force at 0.5 MPa. By default, the factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. This decentralized design eliminates remote valve plumbing, saving panel space across large machines. The carbon steel rod and standard PT tapered threads ensure robust pneumatic performance.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAIF32X200-08B Is Used
Decentralized Machine Stations
Eliminates the need for long air lines from a central valve bank, driving local 32mm actuators directly from a single DC24V signal.
Compact Clamping Fixtures
Saves panel space by integrating the 4M210-08 valve directly on the cylinder, providing 402N of push force for small part clamping.
Space-Constrained Retrofits
Ideal for upgrading existing ISO 15552 machines where routing new valve tubing is costly or physically impossible.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X200-08B the Right Choice?
Choose this 32mm self-valved unit when you need compact decentralized actuation without the tubing runs of a remote valve bank. If your application requires greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. The SAIF32X200-08B specifies a DC24V terminal coil, a 1/4 valve port, and a 1/8 cylinder port with PT threads. To replace it, match the 32mm bore, 200mm stroke, 4M210-08 valve, DC24V voltage, terminal entry, and no magnet (-S). For this 200mm stroke, which is below 300mm, standard guide support is sufficient, but always verify side-load limits. Remember that the 5/2 valve routes air and the end cushions only decelerate near stroke end; neither function locks or holds the load. For true position holding, consider the SAIL lock cylinder.
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 SAIF32X200-08B FAQ
The 32mm bore generates 402N push and 345N pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
No, the SAIF32X200-08B switches itself using the integrated 4M210 valve and a DC24V terminal coil. By factory default, energising the coil retracts the rod, but the valve can be repositioned to extend-when-energised.
