About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-30B
The AirTAC SDAJ100X25-30B is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. A M27x2.0 adjuster screw lets you dial the outward stroke down to 0 mm from the nominal 25 mm maximum directly at the machine, eliminating the need for shims or part swaps. Delivering 3927 N of push force at 0.5 MPa, the mechanism sets the mechanical end position without altering the pneumatic area.
Built with a short riveted body, this unit saves axial mounting depth where a larger profile cylinder will not fit. It uses a fixed NBR bumper at each end to decelerate the stroke, rather than an adjustable air cushion. This specific SKU includes a male M26x1.5 piston rod thread and a PT3/8 air port, operating at speeds between 30 and 500 mm/s.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 25 mm |
| 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 SDAJ100X25-30B Is Used
Heavy Press Fitment
Dial the extend stop precisely for seating heavy bearings, using the 3927 N push force at 0.5 MPa to drive components without over-traveling.
Large Fixture Changeover
Quickly reset the outward stroke from 0 to 25 mm during production line tooling swaps, avoiding the downtime of physically swapping cylinders.
Vertical Lift Dampening
Lift approximately 200.2 kg with a 2:1 safety margin, relying on the fixed NBR bumper to absorb the shock at the upper mechanical stop.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-30B the Right Cylinder?
When sizing this bore, compare it to the adjacent SDAJ80, which provides 2513.3 N of push at 0.5 MPa. Stepping up to this 100 mm bore yields 3927 N at the same pressure, offering a safe working load of roughly 2356 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin. Choose this model if your fixture requires on-site stroke tuning within the 0 to 25 mm window.
Confirm the 100 mm bore, 25 mm stroke, 30 mm adjustment window, PT3/8 port, and male M26x1.5 rod thread suit your mounting plate. Note that this SKU lacks a piston magnet, so it cannot accept reed or electronic switches. Because the fixed bumper only decelerates near the end of travel, a plain cylinder will not hold a load if air pressure drops or the valve centers; install an external rod lock or pilot-operated check valve for secure 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 SDAJ100X25-30B 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 30 mm, giving a usable outward range of 0 to 25 mm. This SKU has no piston magnet and cannot take a switch; the -S variant adds a magnet for reed or electronic sensing.
