Airtac SAIF Series Standard Cylinder with Valve SAIF63X600-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X600-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 600mm 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 SAIF63X600-08A
The AirTAC SAIF63X600-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This specific SKU is configured with a 1/4" valve port, PT1/4 cylinder ports, an AC220V terminal coil, and a carbon steel piston rod. The built-in valve delivers a 25.0 mm2 effective area (Cv 1.40) and operates at a maximum frequency of 4 cycles per second. Because the manifold routes air internally via a PU tube (O10 x O6.5), you eliminate remote plumbing and panel space. The AC coil consumes 3.5 VA, features IP65 protection, and activates in 0.05 seconds or less.
While the cylinder body rates to 1.0 MPa, the practical operating range for this valved unit is 0.15-0.8 MPa, matching the valve limits. At 0.5 MPa it generates 1559 N of push force and 1402 N of pull force. By factory default, the piston rod retracts when the coil is energised, but you can reconfigure the valve to extend-when-energised by simply repositioning it. The 5/2 valve holds its position via internal pilot pressure, not a spring. For load-holding applications that require a physical lock, consider the SAIL series instead.

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)

| 0.7 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 SAIF63X600-08A Is Used
Decentralized Automation
Ideal for large assembly lines where running individual valve tubing back to a central manifold is costly and complex.
Material Handling
Provides robust 1559 N push force at 0.5 MPa for lifting, gating, or positioning heavy workpieces on conveyors.
Space-Constrained Machinery
The integrated valve manifold eliminates the need for a separate valve island, freeing up valuable panel and machine envelope.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X600-08A the Right Choice?
Choose this 63mm bore when a 50mm bore (982 N push at 0.5 MPa) is insufficient, but a 80mm bore (2513 N push at 0.5 MPa) is oversized. A self-valved SAIF is ideal for decentralized stations across large machines, saving wiring and tubing compared to a separate cylinder and remote valve setup. When replacing this unit, match the 63mm bore, 600mm stroke, 1/4" valve port, AC220V voltage, terminal entry, and PT thread. Because the stroke is 600mm, ensure adequate guiding to prevent excessive side loads on the piston rod. This model lacks a magnet; add the -S suffix if you require CMSE reed or DMSE solid-state sensors.
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 SAIF63X600-08A FAQ
The 63mm bore generates 1559 N push and 1402 N pull force at 0.5 MPa. The built-in 4M310-08 valve has a 25.0 mm2 orifice (Cv 1.40) with a maximum frequency of 4 cycles per second.
The integrated 5/2 valve drives the cylinder from one AC220V signal. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised. It holds position via pilot pressure, not a mechanical lock; for true load holding, use a SAIL lock cylinder.
