Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30B 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 45 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30B
The AirTAC SDAJ100X75-30B is a compact double-acting single-rod cylinder engineered with an external adjustable extend stop. By turning the R (M27x2.0) screw, technicians can dial the forward stroke down from 75 mm to 45 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. 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 of push at 0.5 MPa.
This 100 mm bore unit features a robust 32 mm piston rod and a male M26x1.5 thread end for secure heavy-load mounting. Its short riveted body saves valuable axial depth where larger profile or round-body units would fail to fit. End-of-stroke impact is managed by a fixed NBR bumper that decelerates the piston, though it is not an adjustable air cushion or a locking mechanism.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 75 mm |
| Adjustable range | 45 – 75 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 SDAJ100X75-30B Is Used
Press Fit Tuning
Dial in the exact 45 to 75 mm insertion depth for bearing presses on the factory floor without swapping cylinders, leveraging the 3927 N push force for confident seating.
Heavy Vertical Lifts
Lift payloads up to a safe 200.2 kg working load in compact elevators, using the male M26x1.5 rod thread for rigid coupling and the R screw to set precise upper stops.
Assembly Line Changeover
Adapt end-of-arm tooling positions across product variants quickly by turning the M27x2.0 adjuster, saving axial space in tight robotic cells with the short riveted body.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30B the Right Cylinder?
When sizing this model, compare its 3927 N push at 0.5 MPa against adjacent bores. Stepping down to the SDAJ80 yields 2513.3 N, which may be insufficient for heavy pressing or lifting tasks, whereas stepping up to a larger custom bore is rarely feasible in compact footprints. A safe working load is approximately 2356 N, representing about 60 percent of the 0.5 MPa push figure, allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin.
This specific SKU includes the -B option, providing a male M26x1.5 piston rod thread rather than the default female M18x1.5, and uses a PT3/8 air port. Note that it lacks the -S magnet, so it cannot accept AirTAC reed or electronic switches. Remember that a plain cylinder does not hold its load on air loss or valve centering; the fixed bumper only decelerates near the end of travel. For suspended or vertical loads, specify an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–75 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 SDAJ100X75-30B FAQ
This 100 mm bore cylinder delivers a push of 3927 N and a pull of 3524.9 N at 0.5 MPa. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. 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 forward position anywhere between 45 and 75 mm. Retract remains full stroke. Because this SKU lacks the -S magnet, it cannot be used with magnetic switches.
