Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-40B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-40B 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 90 mm on the machine — no shims, no part change.

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. Retract remains full, and because the adjuster only sets the mechanical stop position, output force equals a standard SDA of this bore, delivering 402.1 N of push at 0.5 MPa.
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.

| Acting type | Double acting |
|---|---|
| Rod end thread | M6×1.0 F / M10×1.25 male (B) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
The adjustment screw shortens the extend stroke by up to 40 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
Force matches a standard SDA of the same bore; the adjuster only sets the stop position, not the area. Actual usable force is lower than theoretical due to friction.

Where the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-40B Is Used
Adjustable Clamping Stop
Dial the M10x1.25 screw to set the extend between 50 and 90 mm for varying part widths on a machining pallet, using the 402.1 N push force to secure the workpiece.
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.
Vertical Lift Dampening
Lift loads up to 20.5 kg with a 2:1 margin, relying on the fixed NBR bumper to absorb the end shock at the top of the 90 mm travel without needing an adjustable cushion.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-40B the Right Cylinder?
When sizing this 32 mm bore, compare it both ways: stepping down to an SDAJ25 yields 245.4 N push at 0.5 MPa, while stepping up to an SDAJ40 provides 628.3 N. This SDAJ32X90-40B delivers 402.1 N at 0.5 MPa, translating to a safe working load of roughly 241 N (about 60 percent of capacity) and a vertical lift capability near 20.5 kg with a 2:1 safety margin.
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
At 0.5 MPa this 32 mm bore cylinder provides 402.1 N of push and 345.6 N of pull. At 0.7 MPa it provides 563 N of push and 483.8 N of pull. 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.
