Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20 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 50 to 70 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20
The AirTAC SDAJ100X70-20 is a compact double-acting single-rod cylinder built for heavy-duty positioning where the extend endpoint requires on-site fine-tuning. An external M27x2.0 adjuster screw lets you dial the forward stop anywhere between 50 and 70 mm without swapping parts. Because the mechanism only alters the mechanical stop, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
This 100 mm bore unit features a short riveted body that drastically cuts axial mounting depth compared to conventional large-body options. End-of-stroke energy is managed strictly by a fixed NBR bumper, which decelerates the load but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 70 mm |
| Adjustable range | 50 – 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 20 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 SDAJ100X70-20 Is Used
Press Tooling Setup
Dial in the exact 50-70 mm extend stop on heavy stamping fixtures to prevent over-travel, utilizing the full 3927 N push at 0.5 MPa without changing shims.
Heavy Vertical Lifting
Lift loads up to 200.2 kg with a 2:1 safety margin, relying on the fixed NBR bumper to decelerate the 32 mm rod at the end of the stroke.
Compact Machinery Integration
Install the short riveted body in tight machine frames where axial depth is restricted, achieving high-force actuation without a bulky profile body.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20 the Right Cylinder?
Choosing this 100 mm bore actuator means sizing against its neighbors. Dropping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this model provides 3927 N, giving you a safe working load of roughly 2356 N (about 60 percent of the 0.5 MPa figure) for a 2:1 vertical lift margin of 200.2 kg. Use this size when the smaller bore cannot meet the force demand and you need precise 50-70 mm extend tuning during machine commissioning.
Confirm your parameters before ordering: 100 mm bore, 70 mm max stroke, 20 mm adjust window, PT3/8 air port, female M18x1.5 rod thread, and no magnet. Remember that a plain double-acting cylinder drifts when air is lost or the valve is centered. The fixed bumper and mechanical stop do not lock the load; for vertical or suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 50–70 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 SDAJ100X70-20 FAQ
This 100 mm bore double-acting cylinder provides 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, and a theoretical maximum of 801 kgf at 1.0 MPa. The adjustable stop does not alter these force values.
Turning the R (M27x2.0) external screw mechanically shortens the extend endpoint from the 70 mm maximum down to 50 mm. It sets a hard stop position and does not function as a mid-stroke lock or an adjustable air cushion.
