Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-20 is a genuine double-acting COMPACT cylinder (Ø100mm bore) whose extend end-position is set by an external M27×2.0 adjustment screw. You can dial the stroke anywhere from 60 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-20
The AirTAC SDAJ100X80-20 is a double-acting compact cylinder featuring an external R (M27x2.0) adjuster screw that dials the extend stop between 60 and 80 mm. Because the mechanism sets the mechanical stop rather than altering the piston area, output force equals a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa. The short riveted body saves valuable axial mounting depth where a larger profile cylinder will not fit.
This 100 mm bore unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Operating pressure spans 0.15 to 1.0 MPa, and the piston rod measures 32 mm with a PT3/8 air port. This specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to an -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-20 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 80 mm |
| Adjustable range | 60 – 80 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 20 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 SDAJ100X80-20 Is Used
Heavy Press Fitments
Dial the 60-80 mm extend stop on the fly to seat heavy bearings precisely without re-engineering the press head.
Multi-Product Assembly Lines
Handle rapid tooling changeovers by twisting the M27x2.0 adjuster to shift the extend endpoint for different product heights.
Vertical Lift Stations
Lift loads up to 200.2 kg with a 2:1 margin, tweaking the downward stop exactly to the pallet height for gentle placement.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-20 the Right Cylinder?
When sizing this actuator, evaluate both neighbouring bores with real 0.5 MPa push figures: the SDAJ80 provides 2513.3 N, whereas this 100 mm bore yields 3927 N. A safe working load sits around 2356 N, representing roughly 60 percent of the 0.5 MPa push rating, which allows a vertical lift of approximately 200.2 kg with a 2:1 safety margin. Choose this model when your fixture requires on-site stroke tuning across a 20 mm window during setup or tooling changeovers.
Confirm your parameters: 100 mm bore, 80 mm maximum stroke, 20 mm adjustability, PT3/8 port, female M18x1.5 rod thread, and no magnet. Remember that a plain SDAJ does not hold position or carry load when air is lost or the valve is centred; the fixed bumper only decelerates near the end and the R screw acts as a mechanical stop, not a lock. For load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 60–80 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 SDAJ100X80-20 FAQ
This 100 mm bore double-acting cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
Turning the external M27x2.0 screw shortens the extend stroke by up to 20 mm, yielding a usable extend range of 60 to 80 mm. The retract stroke remains full. This SKU lacks a magnet, so adding reed or electronic switches requires the -S option.
