Airtac SAIF Series Standard Cylinder with Valve SAIF63X800-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X800-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 800mm 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 SAIF63X800-08B
The AirTAC SAIF63X800-08B 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, offering IP65 protection and a rapid 0.05 s activation time. The built-in valve provides an effective flow area of 25.0 mm2 (Cv 1.40) and supports up to 4 cycles per second. Because the 4M310 valve operates at 0.15-0.8 MPa, this defines the practical working pressure range for the assembled unit, even though the bare cylinder body is rated for 1.0 MPa.
Delivering 1559 N of push force at 0.5 MPa, this 63 mm bore unit eliminates the need for a separate remote valve, saving panel space and plumbing. The manifold connects to the cylinder via PU tubing (O10 x O6.5). From the factory, the piston rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised simply by repositioning the valve. It is a self-switching actuator perfect for decentralized machine stations.

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 SAIF63X800-08B Is Used
Decentralized Automation
Ideal for large machines with multiple stations, eliminating long tubing runs by switching directly at the cylinder with a single DC24V signal.
Material Handling
Provides 1559 N of push force at 0.5 MPa for sorting or lifting tasks on conveyors, utilizing the 800 mm stroke for extended reach.
Space-Constrained Retrofits
Fits into tight machine envelopes where mounting a separate valve island is impossible, thanks to the integrated 4M310 manifold block.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X800-08B the Right Choice?
Choose this 63 mm bore SAIF when you need higher thrust than a 50 mm bore (which provides 982 N push at 0.5 MPa) but want to avoid the larger envelope of an 80 mm bore (2513 N push at 0.5 MPa). The integrated 4M310 valve with a 1/4" port and Cv 1.40 provides sufficient airflow for the 800 mm stroke, making it superior to using a remote valve when wiring and pneumatic tubing runs are costly. The DC24V terminal coil provides safe, low-voltage operation. If your application requires holding the load in place without live air pressure, note that the 5/2 valve routes air but does not lock the piston; you should look at the SAIL lock or BSAI clamp-lock series instead. Because the 800 mm stroke exceeds 300 mm, ensure adequate guide support to prevent excessive side-loading on the rod. When ordering a replacement, confirm the 63 mm bore, 800 mm stroke, PT 1/4" valve port, DC24V voltage, terminal entry, PT thread type, and absence of a magnet (-S).
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 SAIF63X800-08B FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. The built-in 4M310-08 5/2 valve has an effective area of 25.0 mm2 (Cv 1.40).
No, the SAIF63X800-08B has a built-in 4M310 valve actuated by a DC24V terminal coil. By default, the rod retracts when energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
