Airtac SAIF Series Standard Cylinder with Valve SAIF100X500S-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X500S-08A is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 500mm stroke and a built-in 4M310-08 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 SAIF100X500S-08A
The AirTAC SAIF100X500S-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. This integrated assembly delivers a Cv of 1.40 and handles substantial loads, offering 3927N push force at 0.5 MPa. It comes with a -S magnet for precise position sensing using AirTAC CMSE reed or DMSE electronic solid-state switches. Because the valve is mounted directly via a manifold block using O10 x O6.5 PU tubing, you save panel space and eliminate remote plumbing. The cylinder port is PT1/2, while the valve features a PT1/4 port. Driven by an AC220V terminal coil drawing 3.5 VA, the unit activates in 0.05s. Although the cylinder body rates to 1.0 MPa, the internal pilot valve operates at 0.15-0.8 MPa, making the practical working range 0.15-0.8 MPa. The factory setting retracts the rod when the coil energises, but you can reposition the valve to extend-when-energised.
This self-switching unit is ideal for decentralized stations across large machines. It switches itself from a single coil signal, removing the need for separate valves and long tubing runs. The assembly includes variable air cushions at both ends to decelerate the heavy 100mm piston, and it holds a true ISO 15552 mounting interface, making it dimensionally interchangeable with standard profile cylinders. The rod is carbon steel.

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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 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 SAIF100X500S-08A Is Used
Decentralized Automation
Perfect for large machine layouts where running remote valve tubing is costly. The integrated valve lets each station control itself locally.
High-Force Clamping
Delivers 3927N of push force at 0.5 MPa for securing heavy workpieces during machining, eliminating the need for external valve banks.
Space-Constrained Retrofit
Ideal for upgrading older machines where panel space is tight. The manifold block and short PU tubing save valuable real estate.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X500S-08A the Right Choice?
Choose this 100mm bore when you need high thrust, as it provides 3927N push force at 0.5 MPa. If your application requires less force, stepping down to an 80mm bore yields 2513N push force at 0.5 MPa and uses the same 4M310 valve series. The SAIF100X500S-08A is specified with an AC220V terminal connection and PT1/4 valve port. If you require load holding or intermediate locking, note that the built-in 5/2 valve only routes air and does not lock the piston; for true load holding, consider the SAIL lock or BSAI clamp-lock cylinder series. Because the stroke is 500mm, ensure you provide adequate guide support to prevent excessive side loads on the rod. When replacing this unit, match the 100mm bore, 500mm stroke, PT1/4 valve port, AC220V 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 SAIF100X500S-08A FAQ
The 100mm bore generates 3927N push force at 0.5 MPa and up to 7068N at 0.9 MPa. The built-in 4M310-08 5/2 valve provides an effective flow area of 25.0 mm2 (Cv 1.40).
Yes, the factory setting retracts the rod when the AC220V coil energises, but you can reposition the valve to extend-when-energised. The built-in valve eliminates separate remote valves, saving wiring and panel space for decentralized control.
