Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30S 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 45 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30S
The AirTAC SDAJ100X75-30S is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the extend stroke down from 75 mm to 45 mm directly on the machine, avoiding part swaps during setup. Because the adjuster only sets the mechanical stop and not the piston area, force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
The short riveted body saves axial mounting depth where a larger profile cylinder will not fit. End-of-stroke deceleration relies on a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 75 mm |
| Adjustable range | 45 – 75 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 SDAJ100X75-30S Is Used
Heavy Press Tonnage Setup
Dial in the 45-75 mm extend stop on the R screw during initial tooling commissioning to apply exactly 3927 N of push force without changing mounting hardware.
200 kg Vertical Lift Fixture
Lift payloads up to 200.2 kg with a 2:1 safety margin, using the adjustable stop to set precise upper travel limits before the fixed NBR bumper takes the shock.
High-Force Changeover Stations
Rapidly reconfigure end positions for different product runs by turning the M27x2.0 adjuster, saving axial space with the compact riveted body in tight cell layouts.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-30S the Right Cylinder?
When sizing this 100 mm bore, look both ways: stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, while this 100 mm bore provides 3927 N. This extra thrust translates to a safe working load of roughly 2356 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity near 200.2 kg with a 2:1 safety margin. Choose the 100 mm bore when you need that specific heavy payload and the 45-75 mm on-site extend tuning window.
Confirm the PT3/8 port, the 32 mm rod with female M18x1.5 thread, and the -S magnet for your sensing needs. Remember that a plain SDAJ does not hold position if air pressure drops or the valve centres; the bumper only decelerates near the end of travel. For suspended or vertical loads, add an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–75 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 SDAJ100X75-30S FAQ
This 100 mm bore 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 of 801 kgf at 1.0 MPa. The external stop screw does not alter these force values.
The M27x2.0 R screw shortens the extend stroke by up to 30 mm, giving a usable 45-75 mm range while retract remains full. The included -S magnet works with AirTAC reed or electronic switches for position sensing, though the mechanical stop itself does not lock the load.
