Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30 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 35 to 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30
The AirTAC SDAJ100X65-30 is a double-acting compact cylinder featuring an external adjustable extend stop. A M27x2.0 adjuster screw lets you dial the forward stroke anywhere between 35 and 65 mm directly on the machine, avoiding part swaps during setup. The short riveted body saves valuable axial mounting depth where a larger profile cylinder would fail to fit.
Because the adjuster only sets the mechanical stop position, the output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa. End-of-travel shock is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 65 mm |
| Adjustable range | 35 – 65 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 SDAJ100X65-30 Is Used
Heavy Press Tuning
Dial the 35-65 mm extend stop on a 3927 N press to set precise material deformation without machining new spacers for every batch.
Large Fixture Alignment
Use the M27x2.0 adjuster to fine-tune clamping depth on bulky assemblies, leveraging the compact riveted body to save floor space.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 margin, relying on the fixed NBR bumper to absorb end-of-stroke shock in lifting rigs.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30 the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force requirements carefully. Stepping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this SDAJ100 provides 3927 N, giving 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 safety margin. Choose the 100 mm bore if the smaller option cannot overcome your friction and payload. Confirm your required extend window is 35-65 mm, the port is PT3/8, and the rod-end thread is female M18x1.5.
This model is built for heavy fixtures requiring on-site stroke tuning during commissioning. A plain cylinder will not hold a load if air pressure drops or the valve is centered; the piston drifts, and the fixed NBR bumper only decelerates near the stroke end. For suspended loads, install an external rod lock or a pilot-operated check valve. This SKU ships without a magnet, so order an -S version if you need position sensing.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–65 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 SDAJ100X65-30 FAQ
This 100 mm bore double-acting cylinder 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. It operates between 0.15 and 1.0 MPa at speeds of 30-500 mm/s.
Turning the external R (M27x2.0) screw shortens the extend stroke by up to 30 mm, giving a usable range of 35-65 mm. The screw acts only as a mechanical stop and does not alter the output force. It is not a lock; the cylinder cannot hold a load without live air pressure.
