Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30B 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 15 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30B
The AirTAC SDAJ100X45-30B is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. A M27x2.0 adjuster screw lets you dial the outward stroke on-site between 15 and 45 mm without changing parts. Because the adjuster only limits travel and not piston area, output matches a standard 100 mm bore SDA, delivering 3927 N of push force at 0.5 MPa.
This thin riveted-body design saves significant axial mounting depth where a larger profile cylinder cannot fit. The unit uses a fixed NBR bumper at each end to decelerate the stroke, rather than an adjustable air cushion. This specific SKU includes a male M26x1.5 piston rod thread and lacks a piston magnet, meaning it cannot host reed or electronic switches without the -S option.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 45 mm |
| Adjustable range | 15 – 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 30 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 SDAJ100X45-30B Is Used
Heavy Press Fitments
Dial the 15-45 mm extend stop precisely during initial tooling setup to seat heavy bearings without over-traveling, leveraging the 3927 N push force safely.
Automated Welding Clamps
Fine-tune the clamping reach on the fly for varied fixture heights, using the compact riveted body to fit within tight robotic cell envelopes.
Vertical Lift Stops
Set exact upward travel limits for 200.2 kg lifts with a 2:1 safety margin, relying on the male M26x1.5 rod for robust load coupling.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30B the Right Cylinder?
When sizing this actuator, compare its 3927 N push at 0.5 MPa against adjacent bores. Stepping down to SDAJ80 yields 2513.3 N, which may be insufficient for heavy tooling, whereas the 100 mm bore provides a safe working load of roughly 2356 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity of 200.2 kg with a 2:1 margin. Choose this model if your fixture requires exact on-machine extend tuning across a 15 to 45 mm window.
Verify your parameters: 100 mm bore, 45 mm maximum stroke, 30 mm adjustment range, PT3/8 air port, and male M26x1.5 rod thread. Remember that a plain cylinder does not hold position on air loss or valve centering; the fixed bumper only decelerates near the end of travel. For suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–45 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 SDAJ100X45-30B FAQ
This 100 mm bore cylinder provides 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 M27x2.0 screw mechanically limits the extend stroke, allowing you to set the outward endpoint anywhere between 15 and 45 mm. It does not alter force, and retract remains full stroke.
