Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-20S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-20S 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 15 to 35 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-20S
The AirTAC SDAJ100X35-20S is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the extend position anywhere between 15 and 35 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Retract remains full length, and because the adjuster only sets the mechanical stop, output force equals a standard SDA of this bore at 3927 N push at 0.5 MPa.
Its short riveted body drastically saves axial mounting depth where a round-body or profile cylinder will not fit. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the piston, which is not an adjustable air cushion. The integrated -S piston magnet supports AirTAC reed or electronic switches for position sensing, and the 32 mm rod handles heavy loads within the 30-500 mm/s speed range.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-20S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 35 mm |
| Adjustable range | 15 – 35 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 SDAJ100X35-20S Is Used
Heavy Press Fit Tuning
Dial the 15-35 mm extend stop on the fly to set precise insertion depths for heavy bearings without swapping mechanical spacers on the line.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 margin, relying on the fixed NBR bumper to decelerate the payload near the end of the stroke.
Compact Forming Press
Fit substantial 3927 N thrust into tight axial machinery envelopes, using the short riveted body where longer cylinders cannot reside.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-20S the Right Cylinder?
When sizing this 100 mm bore, look both ways: moving down, an SDAJ80 delivers 2513.3 N push at 0.5 MPa, whereas this SDAJ100 provides 3927 N. This yields a safe working load of roughly 2356 N, or a vertical lift capacity of about 200.2 kg with a 2:1 safety margin. Choose the 100 mm bore when the smaller frame lacks thrust, and confirm your porting matches the bore-fixed PT3/8 thread.
This model is built for setup-heavy lines needing on-site stroke tuning between 15 and 35 mm. It includes the -S magnet for sensing and a female M18x1.5 rod-end thread. Remember that a plain cylinder does not hold its load on air loss or valve centring; the fixed bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–35 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 SDAJ100X35-20S FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. At 0.7 MPa it provides 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw shortens the extend stop by up to 20 mm, giving a usable extend range of 15 to 35 mm. The included -S magnet works with AirTAC reed or electronic switches for position confirmation.
