About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-40
The AirTAC SDAJ100X55-40 is a double-acting compact cylinder featuring a 100 mm bore and an external adjustable extend stop. A simple turn of the R (M27x2.0) screw lets you dial the outward stroke anywhere between 15 and 55 mm directly on the machine, eliminating the need for shims or part swaps during setup. Because the adjuster only sets the mechanical stop position, the output force remains identical to a standard SDA of this size, delivering 3927 N of push at 0.5 MPa.
Built with a short riveted body, this unit saves valuable axial mounting depth in tight machinery envelopes where larger profile or round-body cylinders cannot fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic sensing without upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-40 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 55 mm |
| Adjustable range | 15 – 55 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 40 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 SDAJ100X55-40 Is Used
Heavy Press Fitment
Dial in the exact 15-55 mm extend stop on the factory floor to seat large bearings precisely, leveraging the 3927 N push force without over-traveling.
Product Changeover Lines
Quickly turn the R (M27x2.0) screw to accommodate different part heights during production runs, saving axial space with the compact riveted body.
Vertical Lift Jigs
Lift loads up to 200.2 kg with a 2:1 safety margin, adjusting the outward reach to clear obstacles before retracting fully.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-40 the Right Cylinder?
When sizing this 100 mm bore actuator, consider the neighboring SDAJ80, which provides 2513.3 N of push at 0.5 MPa. If your application requires less force, stepping down to the 80 mm bore saves footprint and air consumption, but if you need maximum thrust, the 100 mm bore offers a safe working load of roughly 2356 N (about 60 percent of its 3927 N capacity at 0.5 MPa) and can manage a vertical lift of approximately 200.2 kg with a 2:1 safety margin.
This model is ideal for operators who need on-site stroke tuning for changeovers or trial positioning. Keep in mind that a plain SDAJ does not hold position or carry a load if air pressure drops or the valve is centered; the fixed bumper only decelerates the stroke end. For load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve. Confirm your requirements for the 100 mm bore, 55 mm maximum stroke, 40 mm adjust window, PT3/8 port, female M18x1.5 rod thread, and the absence of a magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–55 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 SDAJ100X55-40 FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
The external R (M27x2.0) screw mechanically shortens the extend stroke by up to 40 mm, allowing you to set the outward stop anywhere between 15 and 55 mm without changing parts. The retract stroke remains full. This screw is only a mechanical stop, not a mid-stroke lock; the cylinder will drift if air is lost, so use an external rod lock for load holding.
