Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40B 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 100 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40B
The AirTAC SDAJ100X100-40B is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the forward end-position anywhere between 60 and 100 mm directly on your machine, avoiding shims or part swaps. Because the adjuster only sets the mechanical stop and not the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
This 100 mm bore unit uses a short riveted body to save axial mounting depth where larger profile cylinders cannot fit. It features a male-thread piston rod (M26x1.5) and a PT3/8 air port. 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 without the -S option.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 100 mm |
| Adjustable range | 60 – 100 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 40 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 SDAJ100X100-40B Is Used
Heavy Press Fit Tooling
Dial the 60-100 mm extend stop to set precise insertion depths for heavy bearings, leveraging the 3927 N push force without swapping physical spacers.
Multi-Product Assembly Lines
Speed up changeovers by turning the M27x2.0 adjuster screw to match varying part heights, utilizing the compact riveted body to save floor space.
Vertical Lift Fixtures
Lift loads up to 200.2 kg with a 2:1 safety margin, tweaking the downward stop on the fly to accommodate different stacking heights safely.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40B the Right Cylinder?
When sizing this actuator, evaluate both neighboring bores. Stepping down to the SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. If your application requires a safe working load around 2356 N (approximately 60 percent of the 0.5 MPa push figure) or a vertical lift of roughly 200.2 kg with a 2:1 margin, this model fits perfectly. Choose this cylinder when you need on-site stroke tuning during frequent tooling changeovers.
Confirm your parameters: 100 mm bore, 100 mm maximum stroke, 40 mm adjust window, PT3/8 port, male M26x1.5 rod thread, and no magnet. Remember that a plain compact cylinder drifts when air is lost or the valve centers. The fixed NBR bumper only decelerates the stroke end and the R screw acts as a mechanical stop, neither function locks the load. For secure 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 60–100 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 SDAJ100X100-40B FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. At 0.7 MPa it provides 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The R (M27x2.0) screw mechanically shortens the extend stroke from the 100 mm maximum down to 60 mm, without affecting force. This specific SKU has no magnet, so it cannot take sensors; you must select the -S option for reed or electronic switches.
