Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-30
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-30 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 20 to 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-30
The AirTAC SDAJ100X50-30 is a double-acting compact cylinder featuring a 100mm bore and an external adjustable extend stop. A built-in M27x2.0 screw lets you dial the forward stroke down from the 50mm maximum to as low as 20mm 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 bore, delivering 3927 N of push at 0.5 MPa.
Designed to save axial mounting depth, the short riveted body fits where larger profile cylinders cannot. End-of-stroke deceleration is handled by 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. This specific SKU lacks a piston magnet, meaning it cannot host reed or electronic switches without upgrading to the -S variant.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 50 mm |
| Adjustable range | 20 – 50 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 SDAJ100X50-30 Is Used
Heavy Press Changeovers
Dial the extend stop between 20 and 50mm on the fly to accommodate different material thicknesses in a forming press without swapping out mechanical spacers.
Trial Positioning Jigs
Leverage the 3927 N push force at 0.5 MPa to securely seat heavy components while fine-tuning the exact 20-50mm extension point during initial fixture commissioning.
High-Force Lift Stations
Utilize the compact riveted body to lift substantial payloads in tight vertical spaces, achieving a safe working load of roughly 2356 N for controlled elevation tasks.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-30 the Right Cylinder?
Choosing this 100mm bore provides massive thrust in a compact footprint, pushing 3927 N at 0.5 MPa. If your application requires less force, sizing down to the SDAJ80 yields 2513.3 N at 0.5 MPa, representing the nearest lower boundary. Since this is the largest standard bore in the series, there is no larger option available. The 50mm stroke combined with the 30mm adjustment window allows the rod to lock into any forward position between 20 and 50mm, making it highly effective for trial positioning and heavy changeovers.
Keep in mind that a plain SDAJ does not hold a load if air pressure drops or the valve is centered; the piston will drift. For vertical or suspended loads requiring safety holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve. Confirm your build needs the PT3/8 air port, the female M18x1.5 rod-end thread, and the absence of a magnet before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 20–50 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 SDAJ100X50-30 FAQ
This 100mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa. 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 external M27x2.0 screw acts as a mechanical stop that shortens the extend stroke by up to 30mm. You can set the forward end position anywhere between 20mm and the full 50mm stroke. This adjustment changes the stopping point only, not the cylinder's output force.
