Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50 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 70 to 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50
The AirTAC SDAJ100X120-50 is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you dial the forward end-position anywhere between 70 and 120 mm directly on the machine, avoiding shims or part swaps. The retract stroke remains full length. Because the adjuster merely sets the mechanical stop rather than altering the piston area, output force equals a standard SDA of this bore, delivering about 3927 N push at 0.5 MPa.
Built with a short riveted body, this unit saves axial mounting depth where a larger profile cylinder will not fit. It handles air at 0.15-1.0 MPa and travels at 30-500 mm/s. End shock is managed by a fixed NBR bumper that decelerates the stroke, which is not an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot host reed or electronic switches unless upgraded to the -S variant.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 120 mm |
| Adjustable range | 70 – 120 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 50 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 SDAJ100X120-50 Is Used
Press Tool Changeover
Dial the extend stop from 120 mm down to 70 mm during die swaps, letting operators set precise pressing depths without machining custom spacers.
Heavy Material Forming
Leverage the 3927 N push at 0.5 MPa to bend or seat heavy components, using the external screw to fine-tune the forming position on the production line.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 margin while relying on the fixed NBR bumper to decelerate the downward stroke, protecting the assembly from end-of-travel shock.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50 the Right Cylinder?
When sizing this 100 mm bore, compare its 3927 N push at 0.5 MPa against the adjacent SDAJ80, which yields 2513.3 N at the same pressure. Dropping down sacrifices substantial thrust, whereas stepping up to this bore provides a safe working load of roughly 2356 N, assuming a 60 percent safety margin of the 0.5 MPa figure. In vertical lift scenarios, it can handle around 200.2 kg with a 2:1 margin. Choose this model for heavy setups requiring frequent on-site stroke tuning between 70 and 120 mm.
Confirm the 120 mm maximum stroke, 50 mm adjustment window, and PT3/8 port before integrating. Note that a plain SDAJ does not hold position or load when air is lost or the valve is centred; the fixed bumper only decelerates near the end, and the screw is a mechanical stop, not a lock. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This configuration 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 70–120 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 SDAJ100X120-50 FAQ
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa.
Turning the M27x2.0 adjuster screw shortens the extend stroke by up to 50 mm, providing a usable range of 70 to 120 mm. The screw sets the mechanical stop and does not alter force or lock mid-stroke.
