The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X500-08A 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.
The AirTAC SAIF32X500-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M210-08 5/2 solenoid valve. This integrated manifold block uses an O8 x O5 PU tube to connect the valve to the cylinder, eliminating the need for remote plumbing. Driven by an AC220V terminal entry coil consuming 3.5 VA, it delivers a 0.5 MPa push force of 402N. The integrated valve operates at 0.15-0.8 MPa, which sets the practical working range for the assembled SAIF unit, even though the bare cylinder rates to 1.0 MPa.
By default, the factory setting retracts the piston rod when the coil is energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. Because one coil signal switches the cylinder directly, this design is highly suited for decentralized stations across large machines, saving valuable panel space. The assembly includes a carbon steel rod and variable air cushions at both ends to decelerate the motion near stroke end.

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.

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).
Ideal for large machines with multiple actuation points, allowing a single AC220V signal to drive the cylinder without a central valve bank.
Saves panel space and reduces tubing complexity in tight retrofits where running remote valve lines is impractical.
Provides 402N push force at 0.5 MPa for diverting or sorting tasks, with a built-in 4M210-08 valve ensuring fast 5 cycle/sec response.
Choose this 32mm bore model when a compact, self-valved actuator is required for decentralized installations where running separate valve tubing would be costly or space-prohibitive. If your application requires greater thrust, stepping up to the 40mm bore yields a 628N push force at 0.5 MPa, whereas dropping to a smaller profile is not an option within the SAIF range. The 500mm stroke on this 32mm bore necessitates careful attention to side-load; ensure you use appropriate guide rails to prevent rod binding, as the air cushion only decelerates near stroke end and does not hold the load. For position holding, consider the SAIL lock series instead, as the 5/2 valve routes air but does not lock the load without live pressure.
When replacing this unit, verify the exact bore (32mm), stroke (500mm), valve port code (08 for 1/4"), coil voltage (AC220V), terminal entry, PT tapered threads, and the absence of a magnet (-S not specified). If you need electronic or reed position sensing, select the -S magnet option to pair with AirTAC CMSE or DMSE switches.
Quick checklist
The 32mm bore generates a push force of 402N and a pull force of 345N at 0.5 MPa. The built-in 4M210-08 valve has an effective area of 16.0 mm2 (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
By factory default, the rod retracts when the AC220V coil is energised. Because it uses a 5/2 pilot valve rather than a spring, it can be reconfigured to extend-when-energised by repositioning the valve, and no separate remote valve is needed.
