About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-20B
The AirTAC SDAJ32X100-20B is a double-acting compact cylinder featuring an external R (M10x1.25) adjuster screw that lets you dial the extend stop down from 100 mm to 80 mm directly on the machine. This thin riveted-body design saves valuable axial mounting depth where round-body or profile cylinders cannot fit, and it accommodates standard AirTAC compact-cylinder accessories.
This specific SKU is configured with a male-thread piston rod (M10x1.25) and lacks a piston magnet, meaning it cannot accept reed or electronic switches without switching to the -S variant. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

The adjustment screw shortens the extend stroke by up to 20 mm. SDAJ is a double-rod cylinder. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
SDAJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod SDA push of the same bore. Actual usable force is lower than theoretical due to friction.

Where the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-20B Is Used
Package Diverters
Adjust the male M10x1.25 rod extension on-site to handle varying carton widths on the line, safely moving loads up to the 241 N safe working limit.
Vertical Lift Stops
Set exact raise heights for 20.5 kg payloads using the mechanical stop, relying on the fixed NBR bumper to absorb end-of-stroke shock in tight riveted-body envelopes.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-20B the Right Cylinder?
Choose this 100 mm stroke unit with the 20 mm adjustable window if your application requires frequent on-site stroke tuning during changeovers.
Confirm the bore (32 mm), maximum stroke (100 mm), 20 mm adjustment window, and PT1/8 air port match your pneumatic layout. This SKU specifies the -B male M10x1.25 rod end and no magnet (no -S code). Note that a plain SDAJ does not hold position or load when air is lost or the valve is centred; the fixed bumper only decelerates near the end of travel. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 80–100 mm
- ✓ Force at your working pressure
- ✓ Access to reach the R adjuster
- ✓ Magnet (S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the M10×1.25 adjuster after setting the stroke.
- check Avoid side load on the piston rod.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-20B FAQ
The air port is PT1/8.
The external R (M10x1.25) screw mechanically shortens the extend end-position from 100 mm down to 80 mm without changing the force output. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches; you must select the -S variant for sensing capabilities.
