About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30
The AirTAC SDAJ100X55-30 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 outward stroke down from the 55mm maximum to as low as 25mm directly on the machine, avoiding part swaps during setup changes. Because the adjuster only sets the mechanical stop position, the output force remains identical to a standard 100mm bore SDA, delivering 3927 N of push at 0.5 MPa.
This riveted-body design saves substantial axial mounting depth compared to conventional round-body or profile alternatives, fitting high-force actuation into tight machinery envelopes. The end-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without switching to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 55 mm |
| Adjustable range | 25 – 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 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 SDAJ100X55-30 Is Used
Heavy-Duty Press Fitment
Dial in the exact 25-55mm insertion depth for large bearings on an assembly line, utilizing the full 3927 N push force at 0.5 MPa without swapping physical spacers.
Multi-Product Clamping Station
Adjust the mechanical stop on the fly to accommodate varying cast iron part heights, ensuring rigid 801 kgf maximum clamping pressure in a compact footprint.
Vertical Lift Positioning
Set precise upper travel limits for heavy material lifts, keeping the safe working load around 2356 N (roughly 60% of the 0.5 MPa push figure) for reliable vertical handling.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30 the Right Cylinder?
When sizing this model, evaluate your force requirements both ways. Stepping down to an SDAJ80 provides 2513.3 N of push at 0.5 MPa, which may be insufficient if your application needs the 3927 N generated by this 100mm bore. Stepping up is not an option as this is the largest bore in the series, making this the maximum force choice within the compact family. This cylinder is ideal for heavy pressing or clamping tasks that require frequent on-machine stroke tuning between 25 and 55mm.
Confirm the bore (100mm), full stroke (55mm), adjustment window (30mm), and PT3/8 port before ordering. The rod end thread is female M18x1.5 (or male M26x1.5 if option B is specified). Remember that a plain SDAJ does not hold a load if air pressure drops or the valve is centered; the fixed NBR bumper only decelerates the stroke end. For suspended or vertical loads, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–55 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 SDAJ100X55-30 FAQ
At 0.5 MPa, this 100mm bore cylinder provides 3927 N of push force and 3524.9 N of pull force. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa.
The external R (M27x2.0) screw mechanically limits the extend stroke, allowing you to set the outward travel anywhere between 25mm and 55mm. This screw only acts as a stop and does not alter the output force or lock the piston mid-stroke.
