About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-40B
The AirTAC SDAJ32X90-40B is a double-acting compact cylinder featuring an external extend stop. By turning the R (M10x1.25) adjustment screw, you can dial the forward stroke down by up to 40 mm directly on the machine, yielding a usable extend range of 50 to 90 mm without swapping shims or parts.
This variant features a male-threaded piston rod (M10x1.25) for secure tool mounting and a short riveted body that minimizes axial footprint 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 that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S option.

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

| 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 SDAJ32X90-40B Is Used
Changeover Positioning
Speed up product line changeovers by turning the external stop screw to shift the extended endpoint on the fly, avoiding the need to physically swap cylinder hardware.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-40B the Right Cylinder?
Choose this male-rod (-B) model if your fixture requires an M10x1.25 threaded rod end and you need frequent on-site stroke tuning between 50 and 90 mm during changeovers. It uses a PT1/8 port and operates at 30-500 mm/s. Remember that a plain cylinder drifts when air is lost or the valve is centered—the fixed bumper only decelerates near the end and the R screw is a mechanical stop, not a lock. For load 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 50–90 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 SDAJ32X90-40B FAQ
The theoretical maximum push force is 82 kgf at 1.0 MPa.
The R (M10x1.25) screw mechanically shortens the extend stroke by up to 40 mm, allowing you to set the forward position anywhere between 50 and 90 mm. This specific SKU has no piston magnet and cannot take a switch; you must select the -S variant to use AirTAC reed or electronic sensors.
