Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-50B
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-50B is a genuine double-acting COMPACT cylinder (Ø32mm bore) whose extend end-position is set by an external M10×1.25 adjustment screw. You can dial the stroke anywhere from 50 to 100 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-50B
The AirTAC SDAJ32X100-50B is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. By turning the R (M10x1.25) screw, you shorten the forward stroke on-site across a 50 to 100 mm window without swapping shims or components. The short riveted body saves axial mounting depth where a round-body or profile cylinder will not fit.
This specific SKU includes a male-thread piston rod (M10x1.25) and lacks a piston magnet, meaning it cannot accept magnetic switches. End-of-travel deceleration relies on a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating pressure spans 0.15 to 1.0 MPa, with a proof rating of 1.5 MPa and a speed range of 30-500 mm/s.

The adjustment screw shortens the extend stroke by up to 50 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 SDAJ32X100-50B Is Used
Tooling Changeover Stations
Dial the extend stop from 50 to 100 mm via the M10x1.25 R screw to accommodate varying fixture lengths during product changeovers without machining new spacers.
Trial Positioning Jigs
Use the 50 mm adjustment window to find the exact 20.5 kg vertical lift sweet spot during R&D prototyping before locking down the final mechanical stop.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X100-50B the Right Cylinder?
When sizing this 32 mm bore, evaluate both neighbouring diameters. Choose this model if your fixture requires on-site stroke tuning between 50 and 100 mm, and confirm your setup needs the male M10x1.25 rod end, the PT1/8 port, and the 50 mm adjustment window.
Remember that a plain SDAJ does not hold position or load when air is lost or the valve is centred. The fixed bumper only decelerates the stroke end, and the R screw acts as a mechanical stop, not a lock. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. Since this SKU lacks the -S magnet, position sensing is unavailable; you would need the -S variant to utilize AirTAC reed or electronic switches.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 50–100 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 SDAJ32X100-50B FAQ
The adjustment screw does not alter these force values.
Turning the external R (M10x1.25) screw shortens the extend stroke on-site between 50 and 100 mm. The -B option denotes a male M10x1.25 piston rod end. Note this SKU has no magnet (-S), so magnetic switches cannot be fitted.
