Airtac SAIF Series Standard Cylinder with Valve SAIF63X900S-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X900S-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm 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 SAIF63X900S-08B
The AirTAC SAIF63X900S-08B is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. This integrated manifold block design eliminates the need for a separate remote valve, drastically reducing panel space and plumbing across decentralized machine stations. Driven by a DC24V terminal coil consuming just 3.0 W, it achieves an IP65-rated 0.05 s electrical response. The 4M310-08 valve provides a 25.0 mm2 effective orifice (Cv 1.40) and supports up to 4 cycles per second.
While the base cylinder itself is rated for 1.0 MPa, the practical operating range for this assembled valved unit is 0.15-0.8 MPa, matching the internal pilot valve's limits. At 0.5 MPa it delivers 1559 N of push force and 1402 N of pull force. The factory setting retracts the piston rod when the coil is energised, but you can reposition the valve to extend-when-energised. This 63 mm bore unit includes a magnet for position sensing with AirTAC CMSE (reed) or DMSE (electronic) switches and uses a carbon steel rod with PT tapered threads.

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 SAIF63X900S-08B Is Used
Decentralized Automation Lines
Perfect for large transfer lines where running individual valve tubing back to a main panel is costly. The built-in 4M310 valve allows local DC24V control of the 1559 N push force.
Extended Stroke Material Handling
The 900 mm stroke and 63 mm bore size suit long-travel push operations. The guided load handling and 0.15-0.8 MPa operating range ensure smooth, controlled movement.
Retrofitting Space-Tight Machines
Upgrade older pneumatic setups without adding external valve islands. The integrated manifold and terminal coil entry minimize physical footprint while delivering Cv 1.40 flow.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X900S-08B the Right Choice?
Choose this self-valved SAIF63X900S-08B when a decentralized station requires a robust 1559 N push force at 0.5 MPa without the tubing runs of a remote valve. If your application needs less force, the 50 mm bore neighbor offers 982 N push at 0.5 MPa; if you need more clout, the 80 mm bore provides 2513 N. Because the stroke is 900 mm, you must account for side-load risks and use adequate guide rails to prevent rod binding.
This model switches itself from one DC24V terminal signal, making it ideal for space-tight machines. Remember that the 5/2 valve routes air and does not lock the load mechanically—air cushions only decelerate near stroke ends. For true position holding under pressure loss, specify an AirTAC SAIL lock cylinder instead. When ordering a replacement, match the 63 mm bore, 900 mm stroke, 4M310-08 valve port, DC24V voltage, terminal entry, PT thread, and the -S magnet requirement.
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 SAIF63X900S-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 valve has an effective area of 25.0 mm2 (Cv 1.40) and a maximum frequency of 4 cycles per second.
No, it controls itself from a single DC24V terminal coil signal. By default, the rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve. Note that the 5/2 valve does not hold the load without live pressure.
