Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40 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 80 to 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40
The AirTAC SDAJ100X120-40 is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the forward stroke down from its 120 mm maximum to 80 mm directly on the machine, avoiding part changes. The adjuster strictly dictates the end position; it does not alter the piston area, so you retain the full 3927 N push force at 0.5 MPa inherent to a 100 mm bore.
Built with a short riveted body, this unit saves axial mounting depth where a larger profile cylinder cannot fit. It uses a fixed NBR bumper at the ends to decelerate the stroke, which is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches without upgrading to the -S variant.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 120 mm |
| Adjustable range | 80 – 120 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 SDAJ100X120-40 Is Used
Heavy Press Tonnage Setup
Dial in the exact 80-120 mm extend stop during press commissioning to apply 3927 N of force without over-traveling the tooling.
Large Fixture Changeover
Quickly re-adjust the mechanical stop for varying part heights on a machining line, saving axial space with its compact riveted body.
High-Mass Lift Positioning
Set a precise lower endpoint for heavy vertical lifts, ensuring safe deceleration via the NBR bumper while handling high kinetic energy.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-40 the Right Cylinder?
Choosing this 100 mm bore model provides substantial thrust, 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. Since 100 mm is the largest bore in the SDA family, moving up requires a different cylinder series entirely. This unit is ideal for heavy setups needing on-site stroke tuning across an 80-120 mm window.
Confirm the bore, 120 mm stroke, 40 mm adjust window, and PT3/8 port for your manifold. The rod end thread is female M18x1.5 (or male M26x1.5 on the -B option). Remember that a plain SDAJ does not hold position when air is lost or the valve is centered; the fixed bumper only decelerates near the end. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 80–120 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 SDAJ100X120-40 FAQ
This 100 mm bore cylinder delivers a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, push increases to 5497.8 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 forward end position anywhere between 80 mm and 120 mm. This stop does not change the output force, and the retract stroke remains full length.
