Airtac SAIF Series Standard Cylinder with Valve SAIF63X350-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X350-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 350mm 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 SAIF63X350-08A
The AirTAC SAIF63X350-08A is a double-acting ISO 15552 profile cylinder featuring a built-in 4M310-08 5/2 solenoid valve. Driven by an AC220V terminal coil consuming 3.5 VA, the integrated valve offers a 1.40 Cv flow rate and switches at up to 4 cycles per second. Because the valve mounts directly via a manifold block and O10xO6.5 PU tubing, it eliminates remote plumbing. The assembly operates within a 0.15-0.8 MPa range, as the valve limits the 1.0 MPa cylinder rating, delivering 1559N of push force at 0.5 MPa.
Factory-set to retract the rod when the coil energizes, the valve can be repositioned to extend-when-energized. This self-switching design requires only one coil signal to operate, making it highly effective for decentralized machine stations. It uses a PT1/4 cylinder port and a PT1/4 valve port, and includes adjustable air cushions at both ends to decelerate the stroke.

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 (Ø63mm)

| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 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 SAIF63X350-08A Is Used
Decentralized Automation Stations
Ideal for large machines where running remote valve tubing is costly. The integrated 4M310 valve lets this 63mm cylinder control itself from a single AC220V signal.
Space-Constrained Machinery
Saves valuable panel space by mounting the 5/2 valve directly on the profile barrel. Delivers 1559N push force at 0.5 MPa without external manifolds.
Long-Stroke Handling
The 350mm stroke handles extended material transfer tasks. Ensure external guides are used to manage side loads on the rod during transit.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X350-08A the Right Choice?
Choose this 63mm bore when 50mm bore cylinders lack sufficient thrust; stepping up from a 50mm bore increases push force from 982N to 1559N at 0.5 MPa. Conversely, if 1559N exceeds your requirement, dropping to a 50mm bore saves envelope space. The 350mm stroke is well within the 1500mm maximum standard stroke for this bore, but at this length you must account for side loads and use external guide rods to prevent rod binding.
This self-valved unit outperforms separate cylinder and remote valve setups by drastically cutting tubing, wiring, and panel space. When ordering a replacement, verify the 63mm bore, 350mm stroke, 4M310-08 valve port, AC220V terminal coil, PT thread, and standard carbon steel rod. Note that the built-in 5/2 valve routes air and is not a lock; for load-holding applications, select a SAIL lock or BSAI clamp-lock cylinder.
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 SAIF63X350-08A FAQ
At 0.5 MPa operating pressure, this 63mm bore cylinder delivers 1559N of push force and 1402N of pull force. The built-in 4M310-08 5/2 valve provides an effective area of 25.0 mm2 (Cv 1.40).
No, the integrated 4M310 valve switches the cylinder directly from one AC220V coil signal, saving space and tubing. By default, the rod retracts when the coil is energized, but the valve can be repositioned to extend-when-energized.
