The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X80S-08B is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 80mm 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.
The AirTAC SAIF63X80S-08B is a double-acting ISO 15552 profile cylinder with a built-in 4M310-08 5/2 solenoid valve. Driven by a DC24V terminal entry coil drawing 3.0 W, it delivers a 1559 N push force at 0.5 MPa. The integrated valve manifold uses O10 x O6.5 PU tubing to switch the cylinder directly, eliminating remote plumbing. Because the 5/2 valve operates at 0.15-0.8 MPa, this defines the practical working range for the assembled unit, even though the cylinder body rates to 1.0 MPa.
This self-switching unit includes a magnet for CMSE reed and DMSE electronic sensors. By default, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The carbon steel rod and adjustable air cushions handle dynamic loads, though the valve routes air and does not lock the load mechanically.

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 multiple stations, using one DC24V signal to actuate the cylinder locally without running long air lines to a central valve bank.
Provides 1559 N of push force at 0.5 MPa for holding or clamping workpieces, with built-in air cushions to decelerate the rod smoothly at stroke ends.
Drops into tight envelopes where a separate cylinder and remote valve manifold will not fit, using the integrated 4M310 valve and O10 x O6.5 PU tubing.
Choose this 63 mm bore when a 50 mm cylinder (982 N push at 0.5 MPa) lacks thrust, but an 80 mm bore (2513 N) is excessive. The integrated 4M310 valve offers a 25.0 mm2 (Cv 1.40) flow with a 4 cycle/sec max frequency, matching the 30-800 mm/s speed range. A self-valved SAIF excels in decentralized stations by cutting panel space and valve tubing. For position holding, note that the 5/2 valve does not lock the load; consider SAIL for mechanical locking. Replacement requires a 63 mm bore, 80 mm stroke, PT1/4 cylinder port, 1/4" valve port, DC24V terminal coil, PT thread, and the -S magnet.
Quick checklist
At 0.5 MPa, the 63 mm bore generates a 1559 N push force and a 1402 N pull force. The built-in 4M310-08 5/2 valve provides an effective flow area of 25.0 mm2 (Cv 1.40).
The 5/2 valve is internally piloted and holds its last position by pilot pressure, not a spring. By factory default, energising the DC24V coil retracts the rod, but you can reposition the valve to extend-when-energised. It does not mechanically lock the load.
