Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30SB 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 35 to 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30SB
The SDAJ100X65-30SB is a double-acting compact cylinder featuring a 100mm bore and an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the forward end-position anywhere between 35 and 65mm directly on your 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, alongside a male-thread piston rod (-B) sized at M26x1.5. The short riveted body conserves axial mounting depth where a larger profile cylinder will not fit. End shock is managed by a fixed NBR bumper that decelerates the stroke, but it is not an adjustable air cushion.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30SB |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 65 mm |
| Adjustable range | 35 – 65 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 SDAJ100X65-30SB Is Used
Heavy Press Fitment
Dial the M27x2.0 stop screw to precisely seat large bearings within the 35-65mm window without over-traveling and damaging the 3927 N press tooling.
Multi-Product Changeover
Quickly reconfigure the extend position for different product heights on a high-force assembly line, leveraging the male M26x1.5 rod for robust tool mounting.
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 relying on an external check valve to hold the load safely.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30SB the Right Cylinder?
When sizing this 100mm bore actuator, stepping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, which may be insufficient for heavy loads. The SDAJ100X65-30SB provides a safe working load of roughly 2356 N (about 60% of its 3927 N capacity at 0.5 MPa) and can vertically lift approximately 200.2 kg with a 2:1 safety margin. Choose this model if your assembly line requires frequent on-site stroke tuning between 35 and 65mm.
Verify your requirements against the 65mm maximum stroke, 30mm adjustment window, and PT3/8 air port. The male M26x1.5 rod thread and integrated magnet are confirmed. Note that a plain cylinder does not hold its load when air is lost or the valve is centered; the piston drifts and the fixed bumper only decelerates near the end. 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 35–65 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 SDAJ100X65-30SB FAQ
This 100mm bore actuator features a PT3/8 air port and delivers 3927 N push / 3524.9 N pull at 0.5 MPa, 5497.8 N push / 4934.8 N pull at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa.
