Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 1000mm 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 SAUF Series Valve-Mounted Air Cylinder SAUF50X1000-08A
The SAUF50X1000-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. This 50mm bore delivers 982N push and 825N pull at 0.5MPa, operating within the valve's 0.15-0.8MPa window. The 1/4" valve port yields a 16mm2 flow (Cv 0.89) at up to 5 cycles/sec. The cylinder port is 1/4" with a PT thread, using PU tube Ø8xØ5.
For sizing, the computed safe working load is roughly 589N (about 60% of the 982N push figure at 0.5MPa), translating to a vertical lift capacity of around 50kg with a 2:1 margin. The coil uses terminal entry, is IP65 rated, and responds in 0.05s or less. This SKU lacks the S suffix for a magnet, so it cannot accept a magnetic switch. The 1000mm stroke falls within the 1200mm standard maximum but requires external guidance to prevent rod bending under side loads.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF datasheet. Port options: PT / G.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 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.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000-08A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate to actuate on a single AC220V signal, cutting tubing runs back to a central manifold.
Long-Stroke Material Push
Uses its 1000mm reach to index parts across a wide machine bed, relying on the 982N push force at 0.5MPa.
Independent Stacking Arm
Frees up manifold slots by self-switching via the 4M210-08 valve, ideal for adding a single actuator to an existing cell.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000-08A the Right Choice?
When sizing, compare this 50mm bore (982N push at 0.5MPa) against the neighboring 40mm (628N) and 63mm (1559N) options to match your load within the 0.15-0.8MPa valve operating range. Confirm the AC220V terminal entry coil meets your electrical specs. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Because the 1000mm stroke exceeds 300mm, add an external guide to manage side loads and prevent rod bending. The built-in valve routes air and is not a load lock; if you need to hold a load against air loss or gravity, install an external rod lock or pilot-operated check valve. This unit uses SC-series mounting accessories.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000-08A FAQ
It generates 982N push and 825N pull at 0.5MPa. The built-in valve is a 4M210-08 5/2 solenoid with a 1/4" port, Cv 0.89, and runs up to 5 cycles/sec. The AC220V terminal-entry coil is IP65 rated. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
No, this specific SKU lacks the S magnet suffix and cannot accept a magnetic switch. The default action retracts the rod when the coil is energized, but you can reconfigure it to extend-when-energised simply by repositioning the valve. The valve only routes air, so for load holding you need an external rod lock.
