Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-20B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-20B 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 100 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-20B
The SDAJ100X100-20B is a double-acting compact cylinder featuring a 100 mm bore and a male-threaded piston rod (M26x1.5). An external M27x2.0 adjuster screw lets you dial the extend stop down from the nominal 100 mm to an 80 mm minimum directly at the machine, eliminating the need for shims or part swaps during changeovers. This on-site tuning yields a usable extend window of 80-100 mm, while the retract stroke remains full length.
Force output mirrors a standard SDA of this size, delivering 3927 N of push at 0.5 MPa, because the mechanism sets the mechanical stop rather than altering the piston area. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit. End shock is handled by a fixed NBR bumper that decelerates the stroke, which is not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 100 mm |
| Adjustable range | 80 – 100 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 20 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 SDAJ100X100-20B Is Used
Heavy Press Fitment
Dialing the extend stop from 100 mm down to 80 mm allows precise insertion depth for heavy press operations without machining new spacers.
Automated Welding Clamp
The 3927 N push force secures large steel assemblies, while the male M26x1.5 rod threads directly into heavy-duty tooling.
Vertical Lift Station
Lifts payloads up to 200.2 kg with a 2:1 margin, relying on the fixed NBR bumper to decelerate the load at the extend end.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-20B the Right Cylinder?
When sizing this unit, evaluate both neighbors: stepping down to an SDAJ80 provides 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore yields 3927 N. A computed safe working load is roughly 2356 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift capacity near 200.2 kg with a 2:1 safety margin. Choose this specific model if your fixture requires heavy push force plus on-site extend tuning between 80 and 100 mm.
Confirm your parameters: 100 mm bore, 100 mm max stroke, 20 mm window, PT3/8 port, and a male M26x1.5 rod thread. Note that this SKU lacks the -S magnet, so it cannot accept reed or electronic switches. A plain cylinder does not hold position on air loss; for load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 80–100 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 SDAJ100X100-20B FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. At 0.7 MPa it yields 5497.8 N push and 4934.8 N pull. The theoretical maximum is 801 kgf at 1.0 MPa.
Turning the M27x2.0 screw shortens the extend end position by up to 20 mm, creating an 80-100 mm usable range. It sets the mechanical stop and does not alter force or lock mid-stroke.
