Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-50
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-50 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 SDAJ100X65-50
The AirTAC SDAJ100X65-50 is a compact double-acting single-rod cylinder built for heavy-duty positioning. An external M27x2.0 adjuster screw lets you dial the extend stop anywhere between 15 and 65 mm directly on the machine. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, yielding 3927 N of push at 0.5 MPa.
The short riveted body saves valuable axial mounting depth where a larger profile cylinder will not fit. End-of-travel energy is managed solely by a fixed NBR bumper, which decelerates the mass 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 SDAJ100X65-50 |
|---|---|
| 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 SDAJ100X65-50 Is Used
Press Fit Dial-In
Perfect heavy press fits by turning the M27x2.0 screw to set the exact 15-65 mm extend stop, avoiding over-travel on delicate 200 kg assemblies.
Automated Welding Setup
Position large welding fixtures with 3927 N of force, using the external adjuster to fine-tune electrode contact depth during initial line commissioning.
Heavy Vertical Lifts
Raise payloads up to 200.2 kg vertically with a 2:1 safety margin, relying on the fixed NBR bumper to decelerate the load at the adjusted end position.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-50 the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your neighbours: an SDAJ80 provides 2513.3 N of push at 0.5 MPa, while this 100 mm unit steps up to 3927 N. For context, a safe working load is roughly 2356 N, or about 60 percent of the 0.5 MPa figure, allowing a vertical lift of approximately 200.2 kg with a 2:1 margin. Choose this model when you need on-site stroke tuning to perfect a heavy end-stop without machining shims.
Confirm your parameters: 100 mm bore, 65 mm maximum stroke, 50 mm adjust window, and a PT3/8 port. The rod end features a female M18x1.5 thread, with a male M26x1.5 option available via the B code. Remember that a plain SDAJ does not hold position if air pressure drops or the valve centres; the bumper only decelerates near the end. For secure load holding without live pressure, install an external rod lock or a 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 SDAJ100X65-50 FAQ
This 100 mm bore double-acting cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa, or 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum is 801 kgf at 1.0 MPa. It uses a PT3/8 air port.
Turning the external R (M27x2.0) screw shortens the extend stroke by up to 50 mm, giving a usable range of 15 to 65 mm. This SKU has no piston magnet and cannot take a switch; you must select the -S option to use reed or electronic sensors.
