AirTAC SAU40 Standard Air Cylinder, 40 mm Bore
Every AirTAC SAU40 configuration on one page: 150 stock order codes with strokes from 5 to 1100 mm, 1 mounting style and magnet, seal and thread versions, from $43.13. Pick a stroke, mounting and version to see the exact order code and price.
Basic (no mounting)
This combination is not a stock order code. Request a quote and we will confirm availability and price.
- No minimum order. A single piece can be ordered.
- Ready in 3–5 business days. That is the time we take to process the order and hand it to the carrier. Transit time after that depends on the destination.
About the AirTAC SAU40
The AirTAC SAU40 is a double-acting standard air cylinder with a 40 mm bore and a 16 mm piston rod. At 0.5 MPa it pushes 628 N and pulls 528 N; at 0.7 MPa that rises to 880 N push and 739 N pull. Force depends on bore and pressure only, so every stroke on this page gives the same output.
All SAU40 versions share 1/4" air ports, an M12×1.25 rod thread and 21 mm adjustable air cushions. The cylinder runs on filtered air between 0.15 and 1.0 MPa (proof 1.5 MPa), from -20 to +70 °C, at 30 to 800 mm/s. This page lists 150 stock order codes with strokes from 5 to 1100 mm; catalog standard strokes run up to 1200 mm.
SAU40 Technical Specifications

Theoretical output force (Ø40 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
Push = pressure × bore area; pull subtracts the Ø16 mm rod area. Usable force is lower because of friction and back-pressure.

Where the SAU40 Is Used
Pick-and-place and transfer
About 628 N at 0.5 MPa suits pushers, stoppers and transfer slides.
Packaging machines
Carton pushers, gates and diverters on packaging lines.
Sensed positioning
Magnet versions report stroke ends to the PLC through cylinder sensors.
Choosing the Right SAU40 Configuration
Start with the stroke. Pick the exact travel your machine needs; a longer stroke adds length, weight and air consumption without adding force. If your length is not listed, request a quote and we will confirm whether it can be built.
Then choose the mounting. Basic (no code) uses the cylinder's own mounting holes. Foot and flange mountings hold the cylinder rigid for straight-line loads; clevis and trunnion mountings let it pivot when the load moves in an arc.
Finally pick the version: S adds a magnet for position sensors; the standard seal suits general automation; H (FKM) is for higher temperatures or oil-contaminated air; N specifies NBR.
AirTAC SAU40 FAQ
No. Every SAU40 gives about 628 N push and 528 N pull at 0.5 MPa, whatever the stroke.
1/4" ports, PT thread as standard.
Basic mounting. Use foot or flange for straight-line loads, clevis or trunnion when the cylinder must pivot.
Usually yes. Request a quote with the stroke, mounting and version and we will confirm whether it can be built, plus price and lead time.
0.15 to 1.0 MPa operating pressure (proof 1.5 MPa) and -20 to +70 °C on filtered air.
No. You can order a single SAU40. Orders are processed and handed to the carrier within 3-5 business days.
