Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30SB 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 10 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30SB
The SDAJ100X40-30SB is a double-acting compact cylinder featuring a built-in magnet and a male-thread piston rod. An external M27x2.0 adjuster screw lets you dial the extend stop down from 40 mm to 10 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit.
Turning the R thread sets the mechanical stop position but does not alter the piston area, meaning force equals a standard SDA of this bore at 3927 N push at 0.5 MPa. End shock is managed by a fixed NBR bumper rather than an adjustable air cushion. This unit includes a male M26x1.5 rod end and operates at speeds between 30 and 500 mm/s.

| 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 SDAJ100X40-30SB Is Used
Heavy Press Fitment
Dial the extend stop from 40 mm down to 10 mm during initial tooling setup to find the exact press depth without machining new spacers.
Product Changeover Lines
Quickly adjust the extend endpoint on-site via the M27x2.0 screw when switching between product variants that require different reach distances.
Vertical Lift Stations
Lift loads up to 200.2 kg with a 2:1 safety margin, tweaking the stroke window to accommodate varying package heights on the fly.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30SB the Right Cylinder?
This 100 mm bore delivers 3927 N push at 0.5 MPa, offering a safe working load of roughly 2356 N for a 2:1 margin, or a vertical lift capacity around 200.2 kg. If your application requires less force, sizing down to the SDAJ80 provides 2513.3 N push at 0.5 MPa. Since 100 mm is the largest bore in this compact family, moving up in force requires a different cylinder series entirely.
Choose this model if your assembly line requires frequent trial positioning or on-site stroke tuning within the 10 to 40 mm window. Confirm your port size is PT3/8 and that the male M26x1.5 rod thread suits your tooling. The built-in magnet supports AirTAC reed or electronic switches for end-position sensing. Remember that 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 10–40 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 SDAJ100X40-30SB 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 stroke by up to 30 mm, giving a usable range of 10 to 40 mm. The included magnet works with AirTAC reed or electronic switches for position sensing, while the fixed NBR bumper decelerates the stroke end.
