Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30 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 15 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30
The AirTAC SDAJ100X45-30 is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the M27x2.0 adjuster screw lets you dial the outward stroke on the machine between 15 and 45 mm without changing parts. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, providing 3927 N push at 0.5 MPa.
Its short riveted body drastically reduces axial mounting depth compared to round-body alternatives, fitting heavy-duty actuators into tight machinery footprints. End-of-travel 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 upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 45 mm |
| Adjustable range | 15 – 45 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 SDAJ100X45-30 Is Used
Press Tooling Setup
Dial the 15-45 mm extend stop on the fly during heavy press tooling changes, ensuring the 32 mm rod contacts the workpiece accurately without re-shimming.
Heavy Pallet Forming
Apply the full 3927 N push at 0.5 MPa to seat large packaging components, tweaking the outward reach to accommodate varying pallet thicknesses on the line.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 margin, using the fixed NBR bumper to absorb end shock while setting the exact raise height via the M27x2.0 screw.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30 the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your neighbors: stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, while this 100 mm bore provides 3927 N. A safe working load is roughly 2356 N, assuming a 60 percent margin of the 0.5 MPa figure, translating to a vertical lift capacity of about 200.2 kg with a 2:1 safety factor. Choose this model if your heavy fixture requires exact 15 to 45 mm outward positioning during initial commissioning or frequent changeovers.
Confirm the 45 mm maximum stroke, 30 mm adjustment window, and PT3/8 port match your pneumatic layout. The female M18x1.5 rod-end thread handles high loads, but avoid side loading to preserve seal integrity. Remember that a plain SDAJ does not hold position if air pressure drops or the valve centers; the fixed bumper only decelerates near the end of travel. For suspended loads, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–45 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 SDAJ100X45-30 FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. At 0.7 MPa the push is 5497.8 N and pull is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The external M27x2.0 screw mechanically shortens the extend end-position, yielding a usable outward range of 15 to 45 mm. It sets the physical stop and does not alter force or lock mid-stroke.
