Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-20 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 0 to 15 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-20
The AirTAC SDAJ100X15-20 is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. A front R (M27x2.0) screw lets you dial the extend position down from the nominal 15 mm right to zero, providing exact endpoint tuning directly on the machine without swapping shims or parts. Because the adjuster only sets the mechanical stop, output force remains identical to a standard 100 mm bore SDA, delivering 3927 N of push at 0.5 MPa.
Built with a short riveted body, this unit saves axial mounting depth where a longer cylinder would fail to fit. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the piston, rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches; choose the -S variant if position sensing is required.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-20 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 15 mm |
| Adjustable range | 0 – 15 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 SDAJ100X15-20 Is Used
Short-Stroke Pressing
Delivers 3927 N of thrust at 0.5 MPa for seating bearings, letting the R screw fine-tune the 0-15 mm impact depth without retooling the press head.
Heavy Vertical Lifts
Raises payloads up to 200.2 kg safely with a 2:1 margin, where the compact riveted body minimizes overhead clearance and the stop screw sets exact raise height.
Clamp Position Tuning
Ideal for high-force clamping stations requiring 0 to 15 mm endpoint adjustments during product changeovers, avoiding the need to physically swap cylinder shims.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-20 the Right Cylinder?
When sizing this model, evaluate both neighboring bores. Stepping down to the SDAJ80 yields 2513.3 N of push at 0.5 MPa, which may be insufficient for heavy pressing tasks, whereas this 100 mm bore provides a robust 3927 N. Operating at 0.5 MPa gives a safe working load of roughly 2356 N (about 60 percent of the push figure), translating to a vertical lift capacity near 200.2 kg with a 2:1 safety margin. Choose this unit when your fixture demands maximum thrust in a minimal footprint but still requires minute on-site stroke adjustments.
Confirm your parameters: 100 mm bore, 15 mm maximum stroke, 20 mm adjustment window, and a PT3/8 air port. Remember that a plain SDAJ does not hold position or load when air is lost or the valve is centered, as the fixed bumper only decelerates near the end of travel and the R screw is a mechanical stop, not a lock. For suspended loads, integrate an external rod lock or a pilot-operated check valve. This SKU has no magnet (no -S) and uses a female M18x1.5 rod-end thread.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–15 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 SDAJ100X15-20 FAQ
This 100 mm bore cylinder uses a PT3/8 air port. It generates 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 push of 801 kgf at 1.0 MPa.
The external M27x2.0 screw shortens the extend stroke by up to 20 mm, allowing you to set the extend endpoint anywhere between 0 and 15 mm. This specific SKU has no piston magnet, so it cannot use reed or electronic switches; you must select an -S option code for sensing capabilities.
