Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-40
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-40 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 30 to 70 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-40
The AirTAC SDAJ100X70-40 is a double-acting compact cylinder featuring an external adjustable extend stop. An M27x2.0 adjuster screw lets you dial the outward stroke on-site between 30 and 70 mm without swapping shims or parts. Because the mechanism only limits travel, output force remains identical to a standard SDA of this bore, yielding 3927 N of push at 0.5 MPa.
Its short riveted body saves crucial axial mounting depth where larger profile or round-body units fail to fit. End-of-stroke deceleration relies on a fixed NBR bumper rather than a tunable air cushion. Note this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 70 mm |
| Adjustable range | 30 – 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 40 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 SDAJ100X70-40 Is Used
Heavy Press Tonnage Setup
Dial in the exact 30 to 70 mm extend position during heavy press commissioning to apply precise 3927 N clamping force without part deformation.
200 kg Vertical Lifting
Lift payloads up to 200.2 kg vertically with a two-to-one safety margin, using the M27x2.0 screw to set exact downward travel limits.
Short-Depth Machine Integration
Install the compact riveted body into tight machinery frames where axial depth is restricted, saving space without sacrificing 100 mm bore power.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-40 the Right Cylinder?
When sizing this unit, consider the SDAJ80 which offers 2513.3 N of push at 0.5 MPa, or step up to this 100 mm bore for maximum thrust. The computed safe working load is roughly 2356 N, representing about 60 percent of the 0.5 MPa push rating. This makes it suitable for a vertical lift of approximately 200.2 kg when applying a two-to-one safety margin.
Operators requiring frequent changeovers or trial positioning will benefit from the 30 to 70 mm external stop. Remember that a plain SDAJ does not hold position upon air loss or valve centering; the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This configuration features a 100 mm bore, 70 mm stroke, 40 mm window, PT3/8 port, female rod thread, and no magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–70 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 SDAJ100X70-40 FAQ
This 100 mm bore cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa it yields 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 screw shortens the extend stop by up to 40 mm, allowing an on-machine travel window of 30 to 70 mm. It is strictly a mechanical stop, not a mid-stroke lock; the cylinder drifts on air loss and the NBR bumper only decelerates near the end.
