Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-30SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-30SB 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 20 to 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-30SB
The SDAJ100X50-30SB is a double-acting compact cylinder featuring a built-in magnet and a male-thread piston rod. An external R (M27x2.0) adjuster screw lets you dial the extend stop down from 50 mm to 20 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
Its short riveted body drastically reduces axial mounting depth compared to round-body alternatives, fitting into tight footprints while handling massive loads. The unit relies on a fixed NBR bumper at each end to absorb end-of-stroke shock, operating effectively between 30 and 500 mm/s. This specific configuration includes the -S magnet for AirTAC reed or electronic switches and the -B male M26x1.5 rod-end thread for secure tooling attachment.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 50 mm |
| Adjustable range | 20 – 50 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 SDAJ100X50-30SB Is Used
Heavy Press Fit Tuning
Dial in the exact 20-50 mm extend stop for pressing heavy bearings, using the 3927 N push at 0.5 MPa to seat components without over-traveling.
Multi-Product Changeover Lines
Quickly shift the extend endpoint on the fly via the M27x2.0 screw to accommodate different product heights during manufacturing line changeovers.
Vertical Lift Positioning
Lift loads up to 200.2 kg with a 2:1 safety margin, adjusting the down-stroke stop to prevent crashes in tight vertical assembly spaces.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-30SB the Right Cylinder?
When sizing this 100 mm bore actuator, consider the SDAJ80 as the next step down, which provides 2513.3 N of push at 0.5 MPa. The 100 mm bore is appropriate when you need the full 3927 N push, offering a safe working load of roughly 2356 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin. Choose this model if your application requires precise on-site stroke tuning between 20 and 50 mm alongside heavy thrust.
Confirm the 100 mm bore, 50 mm maximum stroke, 30 mm adjustment window, and PT3/8 port match your pneumatic supply. This variant includes the -S magnet for position sensing and the -B male M26x1.5 rod thread. Remember that a plain cylinder does not hold its load if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, install an external rod lock or a pilot-operated check valve, as the fixed bumper only decelerates near the end of travel.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 20–50 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 SDAJ100X50-30SB FAQ
This double-acting cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
The R (M27x2.0) screw shortens the extend stroke by up to 30 mm, allowing usable travel between 20 and 50 mm. The built-in -S magnet allows you to use AirTAC reed or electronic switches for position sensing along the body grooves.
