Airtac SAIF Series Standard Cylinder with Valve SAIF40X600S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF40X600S-08B is a genuine double-acting ISO 15552 cylinder with a Ø40mm bore, 600mm 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 SAIF40X600S-08B
The AirTAC SAIF40X600S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry, drawing 3.0 W, and includes a magnet for position sensing with CMSE reed and DMSE electronic switches. The built-in valve offers an effective area of 16.0 mm2 (Cv 0.89) and operates at up to 5 cycles per second. Because the valve is mounted directly via a manifold block and O8 x O5 PU tubing, it eliminates the need for a remote valve station, significantly reducing panel space and plumbing complexity.
While the cylinder body itself rates to 1.0 MPa, the integrated valve limits the practical working pressure to 0.15-0.8 MPa. At 0.5 MPa, this 40mm bore generates 628N of push force and 528N of pull force. By default, the factory setting retracts the piston rod when the coil is energised, but this behavior can be reconfigured to extend-when-energised simply by repositioning the valve. The carbon steel rod and variable air cushions ensure stable operation across the 30-800 mm/s speed range.

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 (Ø40mm)

|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 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 SAIF40X600S-08B Is Used
Decentralized Automation
Perfect for large factory layouts where routing individual valve lines back to a main panel is costly, letting each 600mm stroke station control itself locally.
Assembly Line Positioning
Provides reliable 628N push force at 0.5 MPa for actuating clamps or gates on a long conveyor system without needing external pneumatic plumbing.
Machine Retrofitting
Ideal for upgrading existing machinery where space is tight, using the integrated DC24V terminal valve and manifold block to minimize the overall footprint.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF40X600S-08B the Right Choice?
Choose this self-valved SAIF unit when decentralized installation is required across a large machine, as switching from one coil signal is far more efficient than running long pneumatic lines to a centralized valve island. If your application requires higher force, stepping up to the 50mm bore neighbor provides 982N push at 0.5 MPa, but this 40mm bore is optimal for moderate loads. When specifying a replacement, verify the 600mm stroke, 1/4" cylinder port, 4M210-08 valve port, DC24V terminal coil, PT tapered thread, and the -S magnet requirement. For any stroke of 600mm or greater, ensure you use appropriate side-load guides to prevent rod binding, as the air cushions only decelerate the piston near the stroke ends and do not hold the load.
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 SAIF40X600S-08B FAQ
At 0.5 MPa, this 40mm bore cylinder generates 628N of push force and 528N of pull force. The integrated 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.
The integrated 5/2 solenoid valve routes air directly to the cylinder, meaning no separate remote valve is needed. By default, the factory setting retracts the rod when the DC24V coil is energised, but you can reposition the valve to extend-when-energised if needed.
