Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50B 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 30 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50B
The AirTAC SDAJ100X80-50B is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the extend position anywhere between 30 and 80 mm directly on the machine without shims or part changes. Because the adjuster sets the mechanical stop rather than the piston area, output force remains identical to a standard 100 mm bore SDA, delivering 3927 N of push at 0.5 MPa.
This model uses a short riveted body to minimize axial mounting depth where larger profile cylinders cannot fit. It features a male M26x1.5 piston rod thread, a PT3/8 air port, and relies on a fixed NBR bumper at each end to decelerate the stroke. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches; select the -S variant if sensing is required.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 80 mm |
| Adjustable range | 30 – 80 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 SDAJ100X80-50B Is Used
Heavy Fixture Clamping
Dial the extend stop between 30 and 80 mm to accommodate varying casting widths on a machining line without fabricating custom spacers.
Press Platen Positioning
Leverage the 3927 N push force at 0.5 MPa to seat heavy components, using the R screw to fine-tune the bottoming height precisely.
Vertical Lift Stops
Safely lift masses up to 200.2 kg with a 2:1 margin while adjusting the upper extend limit on-site to match different product stack heights.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-50B the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate both neighbours: dropping to an SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this SDAJ100 provides 3927 N. With a 2:1 safety margin, the vertical lift capacity is roughly 200.2 kg, and the safe working load sits around 2356 N (about 60% of the 0.5 MPa push figure). Choose the 100 mm bore when moving heavy platens or fixtures that exceed the 80 mm capacity.
This configuration includes an 80 mm maximum stroke with a 50 mm adjustment window, a PT3/8 port, and a male M26x1.5 rod thread (option B). It is perfect for setups requiring frequent on-machine stroke tuning during changeovers. Remember that a plain cylinder does not hold position on air loss or valve centre; the fixed bumper only decelerates near the end of travel. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–80 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 SDAJ100X80-50B FAQ
This 100 mm bore double-acting cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw mechanically shortens the extend stroke from the 80 mm maximum down to 30 mm. It acts only as a stop and does not lock the piston mid-stroke; a pilot-operated check valve is required to hold a load if air pressure is lost.
