Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-50B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-50B 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 5 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-50B
The SDAJ100X55-50B is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the M27x2.0 adjuster screw lets you dial the forward end-position anywhere between 5 and 55 mm directly on the machine, eliminating the need for shims or part swaps. Because the adjuster sets the mechanical stop rather than the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
Its short riveted body saves valuable axial mounting depth where larger profile or round-body units will not fit. This specific SKU includes a male M26x1.5 piston rod thread and uses a PT3/8 air port. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this base configuration lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.

| Adjustable range | 5 – 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 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 SDAJ100X55-50B Is Used
Heavy Press Fitments
Dial the extend stop from 5 to 55 mm via the M27x2.0 screw to set precise contact depth for heavy pressing tasks without swapping mechanical shims.
Changeover-Intensive Lines
Rapidly reconfigure the forward position for different product sizes, leveraging the 3927 N push force at 0.5 MPa to handle demanding tooling swaps.
Trial Lift Positioning
Safely test vertical lift setups by adjusting the extension in fine increments, achieving a safe working load of roughly 2356 N for a 2:1 safety margin.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-50B the Right Cylinder?
When sizing this 100 mm bore actuator, consider the neighboring options. Stepping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm unit provides 3927 N. If your application requires on-site stroke tuning during frequent changeovers or trial positioning, the 50 mm adjustment window is highly advantageous. Keep in mind that a standard cylinder does not hold a load if air pressure drops or the valve is centered; the piston will drift. For secure load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve. This model confirms a 100 mm bore, 55 mm maximum stroke, 50 mm adjust window, PT3/8 port, no magnet, and a male M26x1.5 rod thread.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–55 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 SDAJ100X55-50B FAQ
At 0.5 MPa it provides 3927 N of push and 3524.9 N of pull. At 0.7 MPa the push is 5497.8 N and the pull is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The R (M27x2.0) screw acts as a mechanical stop, allowing you to shorten the extend stroke by up to 50 mm, giving a usable range of 5 to 55 mm. It does not alter the force output and is not a mid-stroke lock.
