Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40SB 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 80 to 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40SB
The AirTAC SDAJ100X120-40SB is a double-acting compact cylinder featuring an external adjustable extend stop. A M27x2.0 adjuster screw lets you dial the extend position anywhere between 80 and 120 mm directly on the machine, eliminating the need for shims or part swaps. Because the adjuster sets the mechanical stop rather than the piston area, output force remains identical to a standard SDA of this bore, yielding about 3927 N push at 0.5 MPa.
This 100 mm bore unit utilizes a short riveted body to minimize axial mounting depth where a larger profile cylinder will not fit. It includes a built-in piston magnet for AirTAC reed or electronic switches, and a male M26x1.5 piston rod thread. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 120 mm |
| Adjustable range | 80 – 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 40 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 SDAJ100X120-40SB Is Used
Heavy Press Tonnage Setup
Dial in the 80 to 120 mm extend stop on heavy press fixtures to prevent over-travel, utilizing the full 3927 N push force at 0.5 MPa for consistent forming operations.
Automated Welding Clamp
Adjust the male M26x1.5 rod position on the fly for varied weldment thicknesses, relying on the fixed NBR bumper to absorb the 30-500 mm/s travel shock.
Vertical Lift Positioning
Securely lift loads up to 200.2 kg with a 2:1 margin, tweaking the extend endpoint without part changes, provided an external check valve is used for load holding.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40SB the Right Cylinder?
When sizing this actuator, evaluate both neighboring bores against your actual load limits. Dropping down to an SDAJ80 provides 2513.3 N push at 0.5 MPa, while this 100 mm option delivers 3927 N. Based on the 0.5 MPa figure, a safe working load is roughly 2356 N (about 60 percent of capacity), translating to a vertical lift capability of approximately 200.2 kg with a 2:1 safety margin.
Choose this specific configuration when your setup requires frequent on-machine stroke tuning between 80 and 120 mm. Confirm the PT3/8 air port, the 40 mm adjustment window, and the presence of the -S magnet and -B male rod thread. Remember that a plain cylinder does not hold its load on air loss or valve centering; the fixed bumper only decelerates near the end. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 80–120 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 SDAJ100X120-40SB FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. 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 M27x2.0 screw shortens the extend stop by up to 40 mm, allowing an 80 to 120 mm usable range without altering force. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
