Airtac SAIF Series Standard Cylinder with Valve SAIF50X600-08B
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF50X600-08B is a genuine double-acting ISO 15552 cylinder with a Ø50mm bore, 600mm 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.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF50X600-08B
The AirTAC SAIF50X600-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M210-08 5/2 solenoid valve, delivering a Cv of 0.89 and a 16.0 mm2 effective area. Driven by a DC24V terminal coil drawing 3.0 W, it responds in 0.05 s and carries an IP65 rating. The integrated valve operates at 0.15-0.8 MPa, which sets the practical working range for the assembled unit, even though the cylinder body itself rates to 1.0 MPa. With a 50 mm bore, it generates 982 N of push force at 0.5 MPa.
This model switches itself from one coil signal, eliminating the need for a remote valve and reducing panel space and plumbing. The manifold connects to the cylinder via PU tubing (O8 x O5), and the valve port (1/4 inch) differs from the cylinder port (1/4 inch). Factory-set to retract the rod when energised, the valve can be repositioned to extend-when-energised. It uses a carbon steel piston rod and PT tapered threads.

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.
Theoretical Output Force (Ø50mm)

|---|---|---|
| 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 SAIF50X600-08B Is Used
Decentralized Conveyor Diverters
Eliminates long air tubing runs to a central manifold by switching the diverter cylinder directly at the station using the integrated 4M210-08 valve.
Space-Tight Assembly Machines
Saves valuable panel and floor space by mounting the 5/2 valve directly on the cylinder profile, ideal for compact 50 mm bore automation cells.
Retrofit Automation Upgrades
Simplifies electrical upgrades by using a DC24V terminal coil, allowing existing low-voltage wiring to drive the cylinder without adding new pneumatic plumbing.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF50X600-08B the Right Choice?
Choose this 50 mm bore when you need 982 N push force at 0.5 MPa; step down to a 40 mm bore for 628 N, or up to a 63 mm bore for 1559 N if your payload requires more thrust. A self-valved SAIF beats a separate cylinder and remote valve in decentralized installations by cutting tubing runs and wiring complexity. Select this DC24V terminal entry coil for low-voltage safety and direct PLC interfacing. For load holding, note that the 5/2 valve routes air but does not lock the piston; apply a SAIL lock cylinder if the load must be held mechanically.
Because the 600 mm stroke exceeds 300 mm, ensure adequate side-load guidance to prevent rod bending and premature seal wear. Replacement requires matching the 50 mm bore, 600 mm stroke, 1/4 inch valve port, DC24V voltage, terminal entry, PT threads, and no magnet (-S not specified).
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 SAIF50X600-08B FAQ
The 50 mm bore generates 982 N of push force and 825 N of pull force at 0.5 MPa. The built-in 4M210-08 valve provides a 16.0 mm2 effective area (Cv 0.89) and supports a maximum frequency of 5 cycles per second.
No separate valve is needed; the unit switches itself via the built-in 4M210-08 valve driven by a DC24V terminal coil. By default, the piston rod retracts when the coil is energised, but it can be reconfigured to extend-when-energised by repositioning the valve.
