The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X150S-08B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 150mm 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.
The AirTAC SAIF50X150S-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. This built-in valve provides a Cv of 0.89 and eliminates the need for remote plumbing, using an O8xO5 PU tube manifold to route air directly. Equipped with a DC24V terminal coil drawing 3.0 W, it activates in 0.05 s with IP65 protection. The -S magnet enables position sensing with CMSE reed and DMSE electronic switches.
While the cylinder body rates to 1.0 MPa, the practical SAIF operating range is 0.15-0.8 MPa due to the internal pilot valve limits. This 50mm bore generates 982N push force at 0.5 MPa. Factory set to retract when energised, the valve can be repositioned to extend on signal. The carbon steel rod and PT1/4 cylinder port ensure robust, standardised connections.

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.

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).
Ideal for large machines with distributed stations, eliminating long tubing runs to a central valve bank.
Fits into tight machinery layouts where external valve plumbing would consume critical space.
Perfect for upgrading existing ISO 15552 setups to self-contained units, reducing wiring complexity.
Choose this self-valved SAIF unit to simplify decentralized machine stations by removing separate valves and cutting panel space. If your application requires less force, the 40mm bore offers 628N push at 0.5 MPa; for higher loads, the 63mm bore provides 1559N. Select this DC24V terminal configuration for standard low-voltage control panels. To replace, match the 50mm bore, 150mm stroke, 1/4" valve port, DC24V coil, terminal entry, PT thread, and -S magnet. For this 150mm stroke, ensure adequate guide support to prevent rod side-loading.
Quick checklist
The 50mm bore generates 982N push and 825N pull force at 0.5 MPa. The built-in 4M210-08 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a max frequency of 5 cycles/sec.
No, it has a built-in 4M210 5/2 valve driven by a DC24V terminal coil. By default, the rod retracts when the coil is energised, but this can be reconfigured to extend-when-energised by repositioning the valve.
