Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30 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 45 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30
The AirTAC SDAJ100X75-30 is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the forward stroke down from its 75mm maximum to a 45mm minimum directly on the machine without swapping shims or parts. Because the adjuster only sets the mechanical stop position rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering roughly 3927 N of push at 0.5 MPa.
This 100mm bore unit relies on a short riveted body to minimize axial mounting depth where larger profile or round-body variants will not fit. End-of-travel deceleration is handled by a fixed NBR bumper at each end, 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 unless upgraded to an -S variant.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 75 mm |
| Adjustable range | 45 – 75 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 SDAJ100X75-30 Is Used
Heavy Press Tonnage Setup
Dial in the exact 45-75mm extend contact point for high-force stamping or forming tools, utilizing the full 3927 N push at 0.5 MPa to seat heavy components accurately.
Automated Assembly Forming
Adjust the mechanical stop on the production floor during new product changeovers, avoiding part swaps while the fixed NBR bumper absorbs the impact of rapid 100mm bore strokes.
Vertical Lift Positioning
Set a precise lower stopping boundary for heavy vertical lifts, taking advantage of the compact riveted body to save axial space in tight overhead lifting fixtures.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30 the Right Cylinder?
Choosing this 100mm bore provides massive thrust, pushing 3927 N and pulling 3524.9 N at 0.5 MPa. If your application requires slightly less force, sizing down to the SDAJ80 yields 2513.3 N of push at 0.5 MPa, representing the nearest lower boundary. Since 100mm is the largest available bore in this compact family, moving further up in force would require a different cylinder architecture entirely. This model is specified with a PT3/8 port, a 32mm rod, female M18x1.5 rod-end threads, and no magnet.
Operators who need precise, on-site extend positioning between 45 and 75 mm will benefit most from the external R screw. Keep in mind that a plain SDAJ does not hold a load when air is lost or the valve is centered; the piston drifts, and the fixed bumper only decelerates near the end of the stroke. For secure vertical load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–75 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 SDAJ100X75-30 FAQ
This 100mm bore double-acting cylinder delivers 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. It operates between 0.15 and 1.0 MPa, runs at 30-500 mm/s, and handles temperatures from -20 to +70 C.
Turning the external R (M27x2.0) screw mechanically shortens the forward stroke by up to 30mm, allowing the extend stop to be set anywhere between 45 and 75mm on the machine. This adjustment only changes the end-stop position and does not alter the cylinder's output force or act as a mid-stroke lock.
