About the AirTAC SDA40
The AirTAC SDA40 is a double-acting thin compact 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 SDA40 versions share 1/8" air ports, an M8×1.25 female rod thread (B versions have a M14×1.5 male rod end) and rubber bumpers at both ends. 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 500 mm/s. This page lists 164 stock order codes with strokes from 5 to 160 mm; catalog standard strokes run up to 120 mm, and the longer codes are non-standard strokes we already supply.
SDA40 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.
How the SDA40 Order Code Is Built
| SDA40 | Series and bore (40 mm) |
|---|---|

| S | Built-in magnet for position sensors (blank = none) |
| B | Male threaded rod end (blank = female) |
| - | Mounting: basic only |
| H / N | Seal: H = FKM, N = NBR (blank = standard seal) |

Where the SDA40 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 SDA40 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; B gives a male threaded rod end instead of the standard female thread; H (FKM) is for higher temperatures or oil-contaminated air; N specifies NBR; G replaces the standard PT ports with G (BSPP).
AirTAC SDA40 FAQ
No. Every SDA40 gives about 628 N push and 528 N pull at 0.5 MPa, whatever the stroke.
1/8" ports, PT thread as standard. The G version has G (BSPP) ports.
Basic mounting. Use foot or flange for straight-line loads, clevis or trunnion when the cylinder must pivot.
