Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-30
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-30 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 0 to 25 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-30
The AirTAC SDAJ100X25-30 is a compact double-acting single-rod cylinder built for tight-depth mounting where a standard round-body unit fails to fit. Its short riveted body saves valuable axial space while delivering massive thrust. An external M27x2.0 adjuster screw lets you dial the extend stop down from 25 mm to 0 mm directly on the machine without swapping parts.
Because the adjuster only sets the mechanical stop position, output force remains identical to a standard SDA of this bore. You get 3927 N push at 0.5 MPa. End shock is managed by a fixed NBR bumper, which decelerates the piston near the end of travel rather than acting as an adjustable air cushion or a locking brake.

| Adjustable range | 0 – 25 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 SDAJ100X25-30 Is Used
Heavy Press Fit Tuning
Dial the extend stop from 0 to 25 mm to set exact pressing depth for heavy bearings without machining custom spacers.
High-Force Clamping Changeover
Adjust the mechanical stop on-site to accommodate different workpiece heights while maintaining 3927 N of clamping force.
Vertical Lift Positioning
Lift loads up to 200.2 kg with a 2:1 safety margin and fine-tune the extend endpoint to prevent over-travel in tight vertical spaces.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-30 the Right Cylinder?
When sizing this bore, compare its 3927 N push at 0.5 MPa against the adjacent SDAJ80, which provides 2513.3 N at the same pressure. Dropping down loses significant thrust, while stepping up to this 100 mm bore gives you a safe working load of roughly 2356 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity near 200.2 kg with a 2:1 margin. Choose this specific model if your fixture requires on-site extend tuning within the 0 to 25 mm window.
Confirm the 100 mm bore, 25 mm stroke, 30 mm window, and PT3/8 port for your air supply. This SKU lacks a piston magnet, so it cannot host reed or electronic switches; select the -S variant if you need position sensing. Note that a plain cylinder drifts when air is lost or the valve centers—the fixed bumper only decelerates near the end and the screw is a mechanical stop, not a lock. Use an external rod lock or pilot-operated check valve for load holding.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–25 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 SDAJ100X25-30 FAQ
This 100 mm bore cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa it provides 5497.8 N push and 4934.8 N pull. The theoretical maximum push force is 801 kgf at 1.0 MPa.
The external M27x2.0 screw shortens the extend stop by up to 30 mm, allowing you to set the usable extend between 0 and 25 mm. The retract stroke remains full. This mechanism only sets the stop position and does not alter the output force.
