About the AirTAC SDA20
The AirTAC SDA20 is a double-acting thin compact cylinder with a 20 mm bore and an 8 mm piston rod. At 0.5 MPa it pushes 157 N and pulls 132 N; at 0.7 MPa that rises to 220 N push and 185 N pull. Force depends on bore and pressure only, so every stroke on this page gives the same output.
All SDA20 versions share M5 air ports, an M4×0.7 female rod thread (B versions have a M6×1.0 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 128 stock order codes with strokes from 5 to 140 mm; catalog standard strokes run up to 90 mm, and the longer codes are non-standard strokes we already supply.
SDA20 Technical Specifications
| Bore size | Ø20 mm |
|---|---|
| Stock strokes | 5 – 140 mm |
| Catalog standard stroke | up to 90 mm (longer on request) |
| Acting type | Double acting |
| Port size | M5 (PT standard) |
| Piston rod / rod thread | Ø8 mm / M4×0.7 female; M6×1.0 male (B) |
| Fluid | Air (filtered by 40 µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Rubber bumper at both ends |

Theoretical output force (Ø20 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
Push = pressure × bore area; pull subtracts the Ø8 mm rod area. Usable force is lower because of friction and back-pressure.
How the SDA20 Order Code Is Built
| SDA20 | Series and bore (20 mm) |
|---|---|
| X100 | Stroke in 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) |
| G | Port thread: G = G (BSPP), blank = PT |

Where the SDA20 Is Used
Pick-and-place and transfer
About 157 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 SDA20 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.
AirTAC SDA20 FAQ
No. Every SDA20 gives about 157 N push and 132 N pull at 0.5 MPa, whatever the stroke.
M5 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 SDA20. Orders are processed and handed to the carrier within 3-5 business days.
