Airtac SAIF Series Standard Cylinder with Valve SAIF50X800-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X800-08A is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 800mm 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 SAIF50X800-08A
The AirTAC SAIF50X800-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific configuration pairs a 50mm bore with an 800mm stroke and utilizes a PT1/4 tapered thread for both the cylinder and valve ports. Driven by an AC220V terminal-entry coil that draws 3.5 VA, the unit achieves a 0.05s response time while maintaining an IP65 rating. The integrated valve provides a 16.0mm2 effective area (Cv 0.89) and operates at a maximum frequency of 5 cycles per second.
Because the cylinder body rates to 1.0 MPa but the built-in valve operates from 0.15 to 0.8 MPa, the practical working range for this assembled SAIF unit is 0.15-0.8 MPa. At 0.5 MPa, this 50mm bore generates 982N of push force and 825N of pull force. 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. By switching itself from a single coil signal, it eliminates remote valves, reduces tubing, and suits decentralized stations across large machines.

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.

| 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 SAIF50X800-08A Is Used
Decentralized Assembly Stations
Eliminates the need for a central valve bank by driving the 800mm stroke directly from the integrated 4M210-08 valve, reducing tubing runs across large manufacturing lines.
Space-Constrained Machinery
Saves valuable panel space by mounting the 5/2 valve and manifold directly onto the profile cylinder, ideal for compact automated equipment.
Retrofit and Upgrade Projects
Simplifies machine upgrades where running new pneumatic tubing from a remote valve is costly; a single AC220V electrical signal controls the entire motion.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X800-08A the Right Choice?
Choose this self-valved SAIF configuration when a decentralized station requires 982N of push force at 0.5 MPa without the plumbing of a remote valve. If your application demands higher thrust, stepping up to the 63mm bore yields 1559N at the same pressure. The 800mm stroke is well within the 1200mm maximum standard stroke for this bore, but at this length you must account for side-load; ensure external guide rails are used to prevent rod binding. The manifold connects to the cylinder via an O8xO5 PU tube, and the valve port differs from the cylinder port only in application context.
This assembly uses an AC220V terminal connection with PT threads. When specifying replacements, verify the 50mm bore, 800mm stroke, 1/4" valve port, AC220V voltage, terminal entry, and standard carbon steel rod. Remember that the built-in 5/2 valve routes air but does not lock the load; if you need true position holding without live pressure, consider the SAIL lock series. The base profile cylinder is dimensionally interchangeable per ISO 15552.
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 SAIF50X800-08A FAQ
The 50mm bore generates 982N of push force and 825N of pull force at 0.5 MPa. While the cylinder body rates to 1.0 MPa, the built-in 4M210-08 valve limits the practical operating pressure of the assembled unit to 0.15-0.8 MPa.
No, the integrated 4M210-08 5/2 solenoid valve switches the cylinder directly from an AC220V terminal signal. By default, the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised.
