Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-20B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-20B 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 5 to 25 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-20B
The AirTAC SDAJ100X25-20B is a double-acting compact cylinder featuring a male-thread piston rod (M26x1.5) and an external R (M27x2.0) adjuster screw. Turning this screw lets you dial the extend stop down to 5 mm from the 25 mm maximum directly on the machine, avoiding any part swaps during commissioning. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering about 3927 N push at 0.5 MPa.
The short riveted body saves crucial axial mounting depth where larger profile or round-body units will not fit. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the mass but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without switching to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-20B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 25 mm |
| Adjustable range | 5 – 25 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 SDAJ100X25-20B Is Used
Heavy Press Fitment
Dial the extend stop between 5 and 25 mm to set precise pressing depths on heavy assemblies without changing shims, leveraging the 3927 N push at 0.5 MPa.
Tooling Changeover
Quickly readjust the male M26x1.5 rod end position for varied product tooling on automated lines, saving axial space with the compact riveted body.
Vertical Lift Jig
Lift loads up to roughly 200.2 kg with a 2:1 margin, using the external R (M27x2.0) screw to fine-tune the extend endpoint during initial jig setup.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-20B the Right Cylinder?
When sizing this unit, evaluate both neighbours: stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. This makes the 100 mm ideal if the 80 mm falls short of your thrust curve. With a safe working load of roughly 2356 N (about 60 percent of the 0.5 MPa figure), it can manage a vertical lift of approximately 200.2 kg using a 2:1 safety margin.
This model suits operators needing frequent on-site stroke tuning for trial positioning or heavy changeovers. Remember that a plain SDAJ does not hold position or load when air is lost or the valve is centred; the bumper only decelerates near the end and the adjuster is a mechanical stop, not a lock. For load holding without live pressure, install an external rod lock or pilot-operated check valve. Confirm your bore, 25 mm stroke, 20 mm window, PT3/8 port, male M26x1.5 rod thread, and lack of magnet for this configuration.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–25 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 SDAJ100X25-20B FAQ
This 100 mm bore 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 of 801 kgf at 1.0 MPa.
The R (M27x2.0) screw shortens the extend stroke from the 25 mm maximum down to 5 mm without altering force. The -B code indicates a male M26x1.5 piston rod thread. This SKU has no magnet, so it cannot use reed or electronic switches.
