Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30SB 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 SDAJ100X45-30SB
The SDAJ100X45-30SB is a double-acting compact cylinder featuring a 100mm bore and an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the forward stroke down from the 45mm maximum to as low as 15mm directly on the machine, eliminating the need for shims or part swaps. Because the adjuster only sets the mechanical stop and not the piston area, output force remains identical to a standard SDA of this size, delivering 3927 N of push at 0.5 MPa.
This variant includes a built-in piston magnet (-S) for AirTAC reed or electronic switches, and a male-thread piston rod (-B, M26x1.5) for secure tooling attachment. The short riveted body saves valuable axial mounting depth where larger profile or round-body cylinders cannot fit. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the load, rather than an adjustable air cushion.

|---|---|
| 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 SDAJ100X45-30SB Is Used
Heavy Press Fitment
Dial the M27x2.0 adjuster between 15 and 45mm to set exact insertion depths for heavy bearings without swapping physical spacers on the line.
200kg Vertical Lifting
Lifts loads up to roughly 200.2kg safely, using the male M26x1.5 rod for rigid tooling attachment while relying on the fixed NBR bumper to absorb end shocks.
Product Changeover
Quickly reposition the extend stop for varying part heights on a packaging conveyor, utilizing the built-in magnet to confirm end-of-travel via electronic switches.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-30SB the Right Cylinder?
When sizing this 100mm bore actuator, evaluate your force requirements against its neighbors. If you need less push, the SDAJ80 provides 2513.3 N at 0.5 MPa; if you require maximum thrust, this 100mm bore yields 3927 N at 0.5 MPa and a theoretical maximum of 801 kgf at 1.0 MPa. Based on the 0.5 MPa push figure, a safe working load is roughly 2356 N (about 60% capacity), which translates to a vertical lift of approximately 200.2 kg with a 2:1 safety margin.
Choose this specific configuration when your fixture requires on-site stroke tuning across a 15-45mm window. Confirm your setup requires the PT3/8 air port, the M26x1.5 male rod end, and the integrated magnet for switch sensing. Note that a plain compact cylinder does not hold position if air pressure drops or the valve centers—the fixed bumper only decelerates near the end of travel. For load holding without live pressure, install an external rod lock or a 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 SDAJ100X45-30SB FAQ
This 100mm bore double-acting cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa. 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 shortens the forward stroke by up to 30mm, allowing usable extends from 15mm to 45mm without changing parts. The included -S magnet works with AirTAC reed or solid-state electronic switches for position sensing; it does not alter the cylinder's force output.
