Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30B 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 55 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30B
The AirTAC SDAJ100X85-30B is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you set the forward end position anywhere between 55 and 85 mm directly on the machine, eliminating the need for shims or part swaps. Because the adjuster limits travel rather than altering piston area, output force remains identical to 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 thread to handle heavy loads. The short riveted body minimizes axial mounting depth where larger profile cylinders cannot fit. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, so for high-energy cycles you should slow the approach or add an external shock absorber.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 85 mm |
| Adjustable range | 55 – 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 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 SDAJ100X85-30B Is Used
Heavy Press Tonnage Setup
Dial in the 55-85 mm extend stop during press commissioning to apply precise 3927 N clamping force at 0.5 MPa without changing mounting hardware.
Pallet Diverting Changeover
Adjust the male M26x1.5 rod outward to accommodate varying pallet widths on the line, using the fixed NBR bumper to absorb heavy stopping energy.
Vertical Lift Positioning
Lift loads up to 200.2 kg safely with a 2:1 margin, tweaking the extend endpoint on the fly to hit exact vertical placement heights.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30B the Right Cylinder?
Choosing this 100 mm bore provides massive thrust, yielding a safe working load of roughly 2356 N (about 60 percent of the 3927 N push at 0.5 MPa) and a vertical lift capacity near 200.2 kg with a 2:1 safety margin. If your application requires less force, sizing down to the SDAJ80 offers 2513.3 N at 0.5 MPa, which may better suit medium-duty tasks without excessive bulk. This specific SKU includes the male M26x1.5 rod end (-B) and lacks a piston magnet, meaning it cannot accept reed or electronic switches without upgrading to the -S variant.
Engineers who require frequent changeovers or trial positioning benefit most from the 30 mm adjustment window. Remember that a plain compact cylinder does not hold position upon air loss or valve centering; the piston drifts, and the fixed bumper only decelerates near the end of the stroke. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 55–85 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 SDAJ100X85-30B FAQ
At 0.5 MPa this 100 mm bore cylinder provides 3927 N push and 3524.9 N pull. At 0.7 MPa it delivers 5497.8 N push and 4934.8 N pull. The theoretical maximum push force is 801 kgf at 1.0 MPa.
The R (M27x2.0) screw mechanically shortens the extend stroke from the 85 mm maximum down to 55 mm. It sets the physical stop position and does not alter the output force. This SKU lacks the -S magnet option, so it cannot support sensing switches.
