Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40S 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 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40S
The AirTAC SDAJ100X45-40S is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you shorten the forward stroke on-site across a 5 to 45 mm window, eliminating shims or part swaps during changeovers. Retract travel remains full.
Force matches a standard 100 mm bore SDA, delivering 3927 N push at 0.5 MPa because the adjuster sets the mechanical stop, not the piston area. The short riveted body saves axial mounting depth where larger profile cylinders will not fit. End shock is managed by a fixed NBR bumper that decelerates the stroke, which is not an adjustable air cushion. The integrated -S magnet supports AirTAC reed or electronic switches for position sensing.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 45 mm |
| Adjustable range | 5 – 45 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 SDAJ100X45-40S Is Used
Press Tooling Setup
Dial the extend stop from 5 to 45 mm to test forming depths on heavy stamping fixtures without machining new spacers.
Heavy Assembly Stations
Leverage the 3927 N push at 0.5 MPa to seat large components, tweaking the end position instantly for different product variants.
Vertical Lift Stops
Safely lift loads up to 200.2 kg with a 2:1 margin, adjusting the downward stop precisely while relying on external checks for holding.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-40S the Right Cylinder?
When sizing this actuator, evaluate both neighbours: stepping down to SDAJ80 yields 2513.3 N push at 0.5 MPa, while this 100 mm bore provides 3927 N. A safe working load is roughly 2356 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift capacity near 200.2 kg with a 2:1 margin. Choose this model if your fixture requires heavy push force plus frequent on-machine stroke tuning.
Confirm the 45 mm maximum stroke, 40 mm adjust window, PT3/8 port, and the built-in magnet. Remember that a plain cylinder drifts when air is lost or the valve centres; the fixed bumper only decelerates near the end and the R screw is a mechanical stop, not a lock. For secure load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–45 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 SDAJ100X45-40S FAQ
It provides 3927 N push and 3524.9 N pull at 0.5 MPa, or 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw mechanically shortens the extend stop down to 5 mm without altering force. The included -S magnet works with AirTAC reed or electronic switches to confirm end-of-travel positions.
