Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-20SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-20SB 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 20 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-20SB
The AirTAC SDAJ100X40-20SB is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. An M27x2.0 adjuster screw lets you dial the outward stroke on-site between 20 and 40 mm, removing the need for shims or part swaps during machine commissioning. Because the mechanism only sets the mechanical stop position, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
This unit includes a built-in piston magnet for AirTAC reed or electronic switches and a male M26x1.5 rod thread. The short riveted body saves valuable axial mounting depth where larger profile cylinders cannot fit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, so consider an external shock absorber for high-energy loads.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 40 mm |
| Adjustable range | 20 – 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 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 SDAJ100X40-20SB Is Used
Heavy Press Tuning
Dial the 20-40 mm extend stop precisely during setup to apply 3927 N of clamping force without changing out physical spacers on the line.
Vertical Lift Fixtures
Lift loads up to 200.2 kg safely with a 2:1 margin, tweaking the outward reach on the machine to seat heavy components accurately.
Changeover Assemblies
Quickly readjust the extend endpoint for different product heights using the M27x2.0 screw, avoiding teardown while maintaining full retraction.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-20SB the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force requirements bidirectionally. Stepping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore provides 3927 N, giving a safe working load of roughly 2356 N or a 200.2 kg vertical lift with a 2:1 margin. Choose this model when your fixture demands high thrust but requires exact 20-40 mm outward positioning on the fly. Confirm your specific parameters: 100 mm bore, 40 mm max stroke, 20 mm adjust window, PT3/8 port, male M26x1.5 rod, and the magnetic switch option.
Remember that a plain compact cylinder does not hold position or load when air is lost or the valve is centred. The piston will drift, as the fixed NBR bumper only decelerates near the end of travel and the adjuster acts as a mechanical stop, not a lock. For suspended or vertical loads requiring fail-safe 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 20–40 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 SDAJ100X40-20SB FAQ
At 0.5 MPa this 100 mm bore cylinder pushes with 3927 N and pulls with 3524.9 N. At 0.7 MPa push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa, and the air port is PT3/8.
The M27x2.0 screw shortens the extend stop by up to 20 mm, giving a usable outward range of 20-40 mm without altering the 3927 N force. The built-in magnet allows tracking via AirTAC reed or electronic switches but does not interfere with the mechanical stop function.
