Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-50B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-50B 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 0 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-50B
The AirTAC SDAJ100X45-50B is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the extend position down to 0 mm on-site without changing parts, while the retract stroke remains full. Because the adjuster sets the mechanical stop rather than the piston area, output force equals a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
This 100 mm bore unit uses a PT3/8 port and a male M26x1.5 piston rod. Its short riveted body saves valuable axial mounting depth where larger profile cylinders cannot fit. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the piston, but it is not an adjustable air cushion. Note this SKU lacks a piston magnet, so it cannot host reed or electronic switches.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 45 mm |
| Adjustable range | 0 – 45 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 SDAJ100X45-50B Is Used
Heavy Press Fitments
Dial in the exact 0-45 mm extend contact point for pressing heavy bearings without machining custom spacers.
Large Mold Changeover
Adjust the extend stop on the machine to accommodate varying mold thicknesses quickly during production line shifts.
Vertical Lifting Jigs
Lift loads up to 200.2 kg with a 2:1 margin, tweaking the extend reach to clear obstructions on the way out.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-50B the Right Cylinder?
When sizing this model, compare its 3927 N push at 0.5 MPa against the neighboring SDAJ80, which provides 2513.3 N. Stepping up to this 100 mm bore gives a massive 56 percent increase in thrust, ideal for heavy pressing or lifting tasks. The theoretical maximum output is 801 kgf at 1.0 MPa, and a safe working load is roughly 2356 N, allowing a vertical lift of about 200.2 kg with a 2:1 safety margin.
Choose this specific configuration when your fixture requires on-site stroke tuning between 0 and 45 mm. Confirm your setup needs the male M26x1.5 rod thread and the PT3/8 air supply. Remember that a plain cylinder does not hold its load if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–45 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 SDAJ100X45-50B 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 push is 801 kgf at 1.0 MPa.
The external R (M27x2.0) screw mechanically limits the extend stroke, allowing you to set the end position anywhere from 0 to 45 mm. It does not alter the output force, and it is not a mid-stroke lock.
