About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30
The SDAJ100X40-30 is a double-acting compact cylinder featuring a 100mm bore and an external R (M27x2.0) adjuster screw. This mechanism lets you dial the extend stop down from the 40mm maximum to as low as 10mm directly on the machine, eliminating the need for shims or part swaps during changeovers. The short riveted body saves valuable axial mounting depth where a larger profile cylinder simply will not fit.
Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this size, delivering 3927N push at 0.5MPa. 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 host reed or electronic switches.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 40 mm |
| Adjustable range | 10 – 40 mm |
| Adjuster thread (R) | M27×2.0 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M18×1.5 F / M26×1.5 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 30 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3525 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30 Is Used
Press Fit Calibration
Dial in the 10-40mm extend stop during press setup to seat bearings precisely without over-traveling, leveraging the 3927N push force for reliable insertion.
Heavy Material Forming
Adjust the mechanical stop on-site for different material thicknesses, using the fixed NBR bumper to absorb the shock of 801kgf maximum impact at the end of stroke.
Vertical Lift Positioning
Set exact lower stopping points for a 200.2kg vertical lift payload, ensuring the 32mm rod hits the exact 10-40mm window required for safe placement.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30 the Right Cylinder?
When sizing this unit, evaluate your force requirements bidirectionally. Stepping down to an SDAJ80 yields 2513.3N push at 0.5MPa, which is often insufficient for heavy pressing, whereas this 100mm bore provides a safe working load of roughly 2356N (about 60% of its 0.5MPa rating) and can manage a vertical lift of approximately 200.2kg with a 2:1 safety margin. Choose this model if your assembly requires high thrust alongside frequent, on-site stroke tuning between 10mm and 40mm.
Confirm the bore, 40mm stroke, 30mm window, PT3/8 port, and the female M18x1.5 rod-end thread suit your mounting plate. Remember that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near the end of travel and acts as a mechanical stop, not a lock. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–40 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 M27×2.0 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 SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30 FAQ
This 100mm bore model uses a PT3/8 air port. It generates 3927N push and 3524.9N pull at 0.5MPa, 5497.8N push and 4934.8N pull at 0.7MPa, with a theoretical maximum push of 801kgf at 1.0MPa.
The M27x2.0 adjuster screw mechanically shortens the extend stroke from the 40mm maximum down to 10mm without changing the output force. This specific SKU has no piston magnet, so it cannot accept reed or electronic switches; you would need the -S option for sensing.
