Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-75SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-75SB 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 0 to 70 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-75SB
The AirTAC SDAJ100X70-75SB is a double-acting, single-rod compact cylinder featuring a 100 mm bore and an external adjustable extend stop. An M27x2.0 adjuster screw lets you dial the forward stroke from 0 to 70 mm directly on the machine, saving axial mounting depth where a larger body will not fit. The rod end features a male M26x1.5 thread, and the unit includes a built-in magnet for position sensing.
Because the adjuster sets the mechanical stop rather than altering the piston area, output force equals that of a standard SDA at this bore, delivering about 3927 N push at 0.5 MPa. End-of-travel shock is handled by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion. Operating speed ranges from 30 to 500 mm/s.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-75SB |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 70 mm |
| Adjustable range | 0 – 70 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 75 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 SDAJ100X70-75SB Is Used
Heavy Press Fitments
Dial the 0-70 mm extend stop to set precise pressing depth for heavy bearings, leveraging the 3927 N push force without swapping shims.
Multi-Product Forming Lines
Adjust the male M26x1.5 rod end position on the fly during changeovers to accommodate different material thicknesses in a compact footprint.
Vertical Lift Stations
Handle vertical lifts up to 200.2 kg with a 2:1 safety margin, using the external stop to prevent overtravel while requiring a separate check valve for holding.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-75SB the Right Cylinder?
When sizing this 100 mm bore unit, consider the SDAJ80, which yields 2513.3 N push at 0.5 MPa, or step up to this model for 3927 N. The computed safe working load is roughly 2356 N, allowing a vertical lift of about 200.2 kg with a 2:1 margin. Choose this specific configuration when your fixture requires a male M26x1.5 rod thread, a PT3/8 air port, and on-site extend tuning.
Confirm your requirements for the 75 mm adjustment window and the built-in magnet for AirTAC reed or electronic switches. Note that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near the end and the R screw is a mechanical stop, not a lock. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–70 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 SDAJ100X70-75SB FAQ
At 0.5 MPa this 100 mm bore cylinder provides 3927 N push and 3524.9 N pull. At 0.7 MPa it yields 5497.8 N push and 4934.8 N pull. The theoretical maximum push force is 801 kgf at 1.0 MPa.
The M27x2.0 screw shortens the extend stop by up to 75 mm, giving a usable 0-70 mm forward range while retract remains full. The included -S magnet works with AirTAC reed or electronic switches mounted in the body grooves for end-position confirmation.
