Airtac SAIF Series Standard Cylinder with Valve SAIF100X900-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF100X900-08B is a genuine double-acting ISO 15552 cylinder with a Ø100mm bore, 900mm 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 SAIF100X900-08B
The AirTAC SAIF100X900-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a DC24V terminal electrical entry consuming 3.0 W, protected to IP65, and activates in 0.05 s or less. The built-in valve provides a 25.0 mm2 effective orifice (Cv 1.40) and cycles up to 4 times per second. Because the valve manifold is mounted directly to the profile barrel using O10 x O6.5 PU tubing, it eliminates remote plumbing and significantly reduces panel space.
Although the bare cylinder body rates to 1.0 MPa, the operating pressure of the assembled valved unit is 0.15-0.8 MPa, yielding a substantial 3927 N push force at 0.5 MPa and up to 5497 N at 0.7 MPa. From the factory, the piston rod retracts when the coil is energised, but this behavior can be reconfigured to extend-when-energised simply by repositioning the valve. The unit operates at speeds of 30-800 mm/s and utilizes a carbon steel piston rod with M20x1.5 threading.

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 SAIF100X900-08B Is Used
Decentralized Automation
Ideal for large factory layouts where running individual valve tubing back to a central manifold is impractical, allowing each 900 mm stroke station to switch itself locally via a single DC24V signal.
Heavy Material Handling
Provides robust push force up to 5497 N at 0.7 MPa for moving heavy workpieces or lifting pallets, taking advantage of the 100 mm bore and integrated 5/2 valve flow.
Machine Retrofitting
Perfect for upgrading existing ISO 15552 dimensional interfaces without adding external valve islands, saving valuable panel space and simplifying wiring on the factory floor.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF100X900-08B the Right Choice?
Choose this 100 mm bore when a 80 mm bore cannot supply enough thrust; stepping down to an 80 mm bore reduces the push force at 0.5 MPa to 2513 N. The SAIF100X900-08B is optimal for large machines with decentralized stations, as routing a separate remote valve to a 900 mm stroke cylinder is costly and space-intensive. At this stroke length, guiding the load is critical to prevent excessive side-load wear on the seals and rod bearing.
This model uses a 4M310-08 valve with a 1/4" valve port, while the cylinder itself features a larger 1/2" port to handle the high air volume. The coil runs on DC24V power with a terminal entry and PT tapered threads. It does not include a magnet for sensors. Note that the 5/2 valve routes air but does not lock the load mechanically; for position holding, consider an AirTAC SAIL lock cylinder. Replacement parts must match the 100 mm bore, 900 mm stroke, 1/4" valve port, DC24V voltage, terminal entry, and PT thread.
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 SAIF100X900-08B FAQ
At 0.5 MPa, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N. The integrated 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40) to handle the required air volume.
The integrated 4M310 valve is a 5/2 pilot-operated solenoid valve that switches the cylinder via a single DC24V coil signal. By default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve. The valve routes air and does not mechanically lock the load; for position holding, a SAIL lock cylinder is required.
