Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-50B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-50B 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 35 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-50B
The AirTAC SDAJ100X85-50B is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the extend position anywhere between 35 and 85 mm directly on your machine, avoiding shims or part swaps. Because the adjuster only sets the mechanical stop and not the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
This 100 mm bore unit uses a PT3/8 air port and a male M26x1.5 piston rod (option B). The short riveted body drastically reduces axial mounting depth where larger profile cylinders cannot fit. End shock is managed by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion. Note this SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-50B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 85 mm |
| Adjustable range | 35 – 85 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 SDAJ100X85-50B Is Used
Heavy Press Tuning
Dial the 35-85 mm extend stop on-site to set exact 3927 N contact pressure for forming operations without machining new spacers.
200 kg Vertical Lift
Hoist a 200.2 kg payload with a 2:1 safety margin, adjusting the lower stop position precisely to clear varying pallet heights.
Short-Depth Clamping
Utilize the compact riveted body to fit heavy clamping force into tight machine frames where standard cylinders exceed axial limits.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-50B the Right Cylinder?
When sizing this actuator, look both ways: stepping down to the SDAJ80 drops the 0.5 MPa push to 2513.3 N, whereas this 100 mm bore provides 3927 N. A computed safe working load is roughly 2356 N, equating to about 60% of the 0.5 MPa push figure, which allows a vertical lift of approximately 200.2 kg with a 2:1 safety margin. Choose this specific model if your fixture requires on-site stroke tuning to perfect a heavy press or clamping position.
Confirm your parameters: 100 mm bore, 85 mm maximum stroke, 50 mm adjust window, PT3/8 port, male M26x1.5 rod thread, and no magnet. Remember that a plain SDAJ does not hold a load when air is lost or the valve centers; the piston drifts. For load holding without live pressure, install an external rod lock or a pilot-operated check valve. Operating speed spans 30-500 mm/s.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–85 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 SDAJ100X85-50B 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 is 801 kgf at 1.0 MPa.
The M27x2.0 screw shortens the extend stroke by up to 50 mm, yielding a 35-85 mm usable range. A fixed NBR bumper decelerates the stroke end; it is not an adjustable air cushion or a mid-stroke lock.
