Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30SB 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 5 to 35 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30SB
The SDAJ100X35-30SB is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the extend position down to 5 mm from the full 35 mm right on the machine, eliminating shims. Because the adjuster sets the stop rather than the piston area, output equals a standard SDA of this bore, giving about 3927 N push at 0.5 MPa.
This variant includes a built-in piston magnet for AirTAC reed or electronic switches and a male M26x1.5 rod thread. The short riveted body saves axial mounting depth where a round-body or profile cylinder will not fit. A fixed NBR bumper at each end decelerates the stroke end, though it is not an adjustable air cushion or a lock.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30SB |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 35 mm |
| Adjustable range | 5 – 35 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 SDAJ100X35-30SB Is Used
Heavy Press Fit Tuning
Dial in the 5 to 35 mm extend stop on the fly during press tool changeovers, ensuring precise seating force without swapping mechanical shims.
Large Fixture Clamping
Secure oversized weldments by leveraging the 3927 N push at 0.5 MPa, adjusting the clamp reach precisely to accommodate varying part tolerances.
Vertical Lift Positioning
Elevate loads up to 200.2 kg safely with a 2:1 margin, using the M27x2.0 adjuster to set exact upper travel limits for delicate lifting operations.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30SB the Right Cylinder?
When sizing, look both ways: dropping to an SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. The computed safe working load is roughly 2356 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift of approximately 200.2 kg with a 2:1 margin. Choose this unit if your setup-heavy line requires frequent on-machine stroke tuning.
Confirm the 100 mm bore, 35 mm stroke, 30 mm window, and PT3/8 port. The -S magnet enables position sensing, while the -B option supplies the male M26x1.5 piston rod. Note that a plain cylinder does not hold its load on air loss or valve centring; the piston drifts and the bumper only decelerates near the end. For a held load, specify an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–35 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 SDAJ100X35-30SB FAQ
This 100 mm bore cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 screw shortens the extend stop by up to 30 mm, providing a usable extend range of 5 to 35 mm without changing force. The -S option adds a piston magnet compatible with AirTAC reed or electronic switches for position sensing.
