Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-50B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-50B 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 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-50B
The AirTAC SDAJ100X65-50B is a double-acting compact cylinder featuring an external extend stop. A M27x2.0 adjustment screw lets you dial the forward stroke from 15 to 65 mm directly on the machine, avoiding part swaps. The mechanism sets the mechanical stop position, so output force remains identical to a standard SDA of this bore, yielding 3927 N push at 0.5 MPa.
This unit carries the -B option, meaning it uses a male M26x1.5 threaded piston rod rather than the default female cavity. Its short riveted body minimizes axial mounting depth where space is tight. Deceleration at the ends relies on a fixed NBR bumper, which is not an adjustable air cushion. Note this SKU lacks the -S magnet, so it cannot accept reed or electronic switches.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 65 mm |
| Adjustable range | 15 – 65 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 50 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 SDAJ100X65-50B Is Used
Heavy Press Tuning
Dial the M27x2.0 screw to set the exact 15-65 mm extend stop for heavy pressing tasks, ensuring precise force delivery without changing parts.
Large Product Changeover
Adjust the extend position on-site when switching between large product sizes on a line, using the full 3927 N push to handle substantial loads.
Vertical Lift Setup
Lift loads up to roughly 200.2 kg with a 2:1 safety margin, tweaking the stroke window during commissioning to perfect the elevation height.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-50B the Right Cylinder?
When sizing this actuator, evaluate the neighboring bores. Stepping down to SDAJ80 provides 2513.3 N push at 0.5 MPa, whereas this 100 mm bore delivers 3927 N. If your application requires on-site stroke tuning during frequent changeovers, the 50 mm adjustment window is ideal. Based on the 0.5 MPa figure, a safe working load is roughly 2356 N (about 60 percent of capacity), allowing a vertical lift of approximately 200.2 kg with a 2:1 margin.
Confirm your parameters: 100 mm bore, 65 mm maximum stroke, 50 mm adjust window, PT3/8 port, and male M26x1.5 rod thread. Remember that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near the end of travel and does not function as a lock. 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 15–65 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 SDAJ100X65-50B 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 screw mechanically shortens the extend stop from the 65 mm maximum down to 15 mm. It does not alter force. The cylinder cannot hold a load on air loss; you need an external rod lock or pilot-operated check valve for that.
