About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75B
The AirTAC SDAJ32X85-75B is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. By turning the R (M10x1.25) screw, you can dial the extend stroke on-site anywhere between 10 and 85 mm without changing parts.
This variant uses a male M10x1.25 piston rod thread for direct tool or fixture mounting. The short riveted body saves valuable axial depth where space is tight. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note this SKU lacks a piston magnet, so it cannot host reed or electronic switches.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

| 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 SDAJ32X85-75B Is Used
Variable Length Diverter
Adjust the extend position on the fly to route mixed carton sizes down specific lanes, using the compact riveted body to fit within tight transfer frame clearances.
Adjustable Sealing Jaw
Set the precise 20.5 kg vertical clamping reach for varied pouch heights, relying on the fixed NBR bumper to absorb the end-of-stroke impact without damaging the product.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75B the Right Cylinder?
Stepping down to an SDAJ25 yields 245.4 N, whereas stepping up to an SDAJ40 provides 628.3 N.
Choose this unit when your fixture requires on-site stroke tuning between 10 and 85 mm via the M10x1.25 adjuster. It features a PT1/8 port and a male M10x1.25 rod thread. Remember that a plain cylinder drifts when air is lost or a valve centers; the fixed bumper only decelerates the stroke end and does not lock the load. For secure holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–85 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 SDAJ32X85-75B FAQ
The theoretical maximum push force is 82 kgf at 1.0 MPa.
Turning the external R (M10x1.25) screw mechanically shortens the extend stroke by up to 75 mm, giving a usable range of 10 to 85 mm without altering the force. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches; you would need the -S variant for sensing.
