The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X160-08B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 160mm 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 SAIF50X160-08B is a double-acting ISO 15552 profile cylinder featuring an integrated 4M210-08 5/2 solenoid valve. Driven by a DC24V terminal connection coil consuming 3.0 W, it delivers a Cv of 0.89 and responds in 0.05 s. The assembly operates within a 0.15-0.8 MPa range, as the built-in valve limits the broader 1.0 MPa cylinder rating. It generates 982 N of push force at 0.5 MPa.
By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The manifold links the valve to the cylinder using O8 x O5 PU tubing. This decentralized design eliminates remote plumbing, saving panel space and requiring only one electrical signal to drive the actuator.

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 factory layouts where running individual valve lines is costly. The integrated 4M210-08 valve lets this cylinder switch itself from a single DC24V signal.
Saves panel space by mounting the valve directly on the cylinder. Delivers 982 N of push force at 0.5 MPa for secure, localized clamping without remote plumbing.
The profile cylinder design with built-in manifold and O8 x O5 PU tubing minimizes envelope size, fitting easily into tight conveyor diverting or sorting mechanisms.
Select this 50mm bore model when an application requires 982 N of push force at 0.5 MPa. If you need less force, step down to the 40mm bore which offers 628 N push at 0.5 MPa. The 160mm stroke is well within the 1200mm maximum standard stroke for this bore, keeping the unit readily available. Because the 4M210-08 valve handles switching directly at the cylinder, this SAIF configuration is superior to a separate cylinder and remote valve when minimizing tubing and wiring across large machines is critical.
Remember that the 5/2 valve routes air but does not lock the load; if you need true position holding under pressure loss, consider the SAIL lock series. For side loads on this 160mm stroke, use an external guide to prevent rod binding. To replace this unit, match the 50mm bore, 160mm stroke, 1/4" cylinder port, 08 valve port, DC24V voltage, PT thread, terminal entry, and no magnet.
Quick checklist
The 50mm bore generates 982 N of push force and 825 N of pull force at 0.5 MPa. The integrated 4M210-08 5/2 valve provides an effective area of 16.0 mm2 (Cv 0.89) with a maximum frequency of 5 cycles per second.
It uses a 5/2 internal piloted solenoid valve that holds its position by pilot pressure, not a spring. The factory setting retracts the rod when the DC24V terminal coil is energised, but you can reposition the valve to extend-when-energised. This eliminates the need for a separate remote valve.
