Airtac SAIF Series Standard Cylinder with Valve SAIF50X900S-06B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X900S-06B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 900mm stroke and a built-in 4M210-06 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 SAIF50X900S-06B
The AirTAC SAIF50X900S-06B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-06 5/2 solenoid valve. Driven by a DC24V terminal coil drawing 3.0 W, it delivers a Cv of 0.78 and generates 982N of push force at 0.5 MPa. The cylinder port is PT1/4, while the valve manifold feeds it via a PT1/8 port using O8xO5 PU tubing. Because the valve operates at 0.15-0.8 MPa, this defines the practical working range for the assembled unit, despite the bare cylinder rating of 1.0 MPa.
This self-switching unit eliminates the need for a separate remote valve, saving panel space and tubing in decentralized machine layouts. It includes a magnet for CMSE reed and DMSE electronic sensors. The factory setting retracts the rod when the coil is energised, but you can reposition the valve to extend-when-energised. The standard carbon steel rod and PT tapered threads ensure robust sealing for industrial pneumatics.

| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAIF50X900S-06B Is Used
Decentralized Conveyor Gates
Ideal for diverting packages on long conveyor lines where installing remote valves is impractical, utilizing the built-in 4M210 valve for localized switching.
Space-Tight Machinery
Saves valuable panel and floor space in compact automated machinery by eliminating the tubing and hardware required for a separate external valve bank.
Retrofit Automation
Perfect for upgrading older machines where routing new pneumatic tubing across the plant is costly; simply run a DC24V electrical signal to the terminal coil.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X900S-06B the Right Choice?
Choose this 50mm bore when you need 982N push force at 0.5 MPa; step down to a 40mm bore (628N push) for lighter loads, or up to a 63mm bore (1559N push) if higher thrust is required. The integrated 4M210-06 valve with a DC24V terminal connection makes it perfect for decentralized stations where running wiring to a remote valve bank is costly. Remember that the 5/2 valve routes air and is not a lock; for load-holding applications, consider an AirTAC SAIL lock cylinder. When replacing, match the 900mm stroke, PT1/8 valve port, DC24V coil, terminal entry, and -S magnet.
Because the 900mm stroke exceeds 300mm, ensure adequate guidance to prevent side-loading damage to the extruded aluminum barrel and rod seals. The cylinder speed ranges from 30-800 mm/s, controlled by the integrated valve's 5 cycle/sec max frequency.
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 SAIF50X900S-06B FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982N of push force and 825N of pull force. The integrated 4M210-06 5/2 valve has an effective area of 14.0 mm2 (Cv 0.78) and supports a max frequency of 5 cycles per second.
No separate pilot is needed; it is internally piloted. The 5/2 valve holds its last position via pilot pressure, not a spring. By factory default, the rod retracts when the DC24V coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
