Airtac SAIF Series Standard Cylinder with Valve SAIF32X500-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X500-08B is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 500mm 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 SAIF32X500-08B
The AirTAC SAIF32X500-08B is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a 0.89 Cv flow and 16.0 mm2 orifice. Operating on DC24V via a terminal electrical entry, the coil consumes 3.0 W with an IP65 rating and a rapid 0.05 s response time. The integrated manifold connects to the cylinder using an O8 x O5 PU tube, while the valve features a 1/4" port and the cylinder body uses a 1/8" port. Although the bare cylinder rates to 1.0 MPa, the practical SAIF working range is 0.15-0.8 MPa due to the internal pilot valve limits.
This assembly delivers 402 N of push force at 0.5 MPa using its 12 mm carbon steel rod. By default, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. It switches itself from a single coil signal, eliminating remote plumbing and panel space for decentralized stations. The base unit is dimensionally interchangeable per ISO 15552, and the rod retracts smoothly on its 27 mm variable air cushions.

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 SAIF32X500-08B Is Used
Decentralized Stations
Ideal for large machines with decentralized stations, eliminating long runs of valve tubing by controlling the 32 mm bore directly at the point of action.
Compact Assembly
Fits into space-tight machinery where panel space is scarce, using the built-in 4M210 valve and DC24V terminal wiring to minimize footprint.
Retrofit Projects
Perfect for retrofits where running new pneumatic tubing to a remote valve bank is costly, offering a self-switching 500 mm stroke solution.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X500-08B the Right Choice?
Choose this 32 mm bore if you need 402 N push force at 0.5 MPa; stepping down is not an option, but moving up to a 40 mm bore yields 628 N push force for heavier loads. A self-valved SAIF beats a separate cylinder plus remote valve when you need to save space and wiring across decentralized stations. Because the 5/2 valve routes air without locking it, this unit does not hold loads without live pressure; for position holding, consider the SAIL lock cylinder. To replace this exact unit, match the 32 mm bore, 500 mm stroke, 1/4" valve port, DC24V voltage, terminal entry, PT thread, and no magnet. Since the 500 mm stroke exceeds 300 mm, ensure proper guide support to prevent excessive side loading on the rod.
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 SAIF32X500-08B FAQ
The 32 mm bore provides 402 N push and 345 N pull force at 0.5 MPa. The built-in 4M210-08 5/2 valve has a 16.0 mm2 orifice with a 0.89 Cv flow coefficient.
No, the 5/2 valve routes air but does not lock the load without live pressure. Factory setting retracts the rod when the DC24V coil is energised, but you can reposition the valve to extend-when-energised.
