Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-100S
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-100S 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 0 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-100S
The AirTAC SDAJ32X85-100S 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 by up to 100 mm, yielding a usable extend range of 0 to 85 mm directly on the machine.
Its short riveted body saves axial mounting depth where round-body or profile cylinders will not fit. The unit relies on a fixed NBR bumper at each end to decelerate the stroke end, which is not an adjustable air cushion. Equipped with a built-in piston magnet (-S), it supports AirTAC reed or electronic switches for position sensing.

The adjustment screw shortens the extend stroke by up to 100 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 SDAJ32X85-100S Is Used
Changeover Adjustment
Speed up production line changeovers by turning the M10x1.25 adjuster screw to set new end positions on the fly, avoiding the need to swap out physical shims.
Test Fixture Positioning
Sweep through various extend lengths during prototype testing, relying on the fixed NBR bumper to absorb end shocks while finding the exact contact point.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-100S the Right Cylinder?
Choose this model if your fixture requires frequent trial positioning or on-site stroke tuning without part changes. Note that a plain cylinder does not hold its load on air loss or when the valve is centred, as the piston drifts and the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve. Confirm your requirements for the 32 mm bore, 85 mm stroke, 100 mm window, PT1/8 port, female M6x1.0 rod thread, and the -S magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–85 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 SDAJ32X85-100S FAQ
The theoretical maximum push is 82 kgf at 1.0 MPa.
The R (M10x1.25) screw shortens the extend stop by up to 100 mm, giving a usable forward range of 0 to 85 mm. The included -S magnet allows you to mount AirTAC reed or electronic switches directly into the body sensor grooves for position feedback.
