Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50B is a genuine double-acting COMPACT cylinder (Ø80mm bore) whose extend end-position is set by an external M20×1.5 adjustment screw. You can dial the stroke anywhere from 0 to 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50B
The AirTAC SDAJ80X50-50B is a compact double-acting single-rod cylinder built for applications requiring precise extend positioning. An external M20x1.5 adjustment screw lets you dial the extend stop anywhere between 0 and 50 mm directly on the machine, while the retract stroke remains full. Because the adjuster sets the mechanical stop rather than altering the piston area, output force equals a standard SDA of this bore, delivering 2513.3 N of push at 0.5 MPa.
The short riveted body saves valuable axial mounting depth where a larger profile cylinder will not fit. This specific SKU features a male M22x1.5 piston rod thread and a PT3/8 air port. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this variant ships without a piston magnet, so it cannot host reed or electronic switches.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 50 mm |
| Adjustable range | 0 – 50 mm |
| Adjuster thread (R) | M20×1.5 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M14×1.5 F / M22×1.5 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SDAJ80X50-50B Is Used
Heavy Press Tonnage Setup
Dial the 0-50 mm extend stop to precisely set forming depth on a 128.1 kg vertical press tool, ensuring perfect crimps without swapping mechanical spacers.
Product Diverting Changeover
Adjust the extend position on the fly to handle different package widths on a sorting line, leveraging the 2513.3 N push force to positively redirect heavy cartons.
Clamp Stroke Tuning
Fine-tune the clamping reach for varying fixture heights during production trials, using the male M22x1.5 rod to secure custom jaws while the fixed NBR bumper absorbs end shocks.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X50-50B the Right Cylinder?
When sizing this 80 mm bore actuator, compare its 2513.3 N push at 0.5 MPa against adjacent bores: stepping down to an SDAJ63 yields 1558.6 N, while moving up to an SDAJ100 provides 3927 N. Based on the 0.5 MPa figure, a safe working load is approximately 1508 N (about 60 percent of capacity), translating to a vertical lift capability of roughly 128.1 kg with a 2:1 safety margin. Choose this male-rod (M22x1.5) model when your tooling requires a threaded external attachment.
This cylinder is ideal for setup-heavy lines requiring frequent changeovers or trial positioning. Remember that a plain SDAJ does not hold position or load when air is lost or the valve is centred; the fixed bumper only decelerates near the end of travel and the R screw is a mechanical stop, not a lock. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve. Confirm your requirements for the 50 mm stroke, 50 mm adjust window, PT3/8 port, and lack of a magnet (-S) before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–50 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 M20×1.5 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 SDAJ80X50-50B FAQ
This 80 mm bore cylinder features a PT3/8 air port and delivers 2513.3 N push / 2267.8 N pull at 0.5 MPa, 3518.6 N push / 3175 N pull at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
The external M20x1.5 screw shortens the extend stroke by up to 50 mm, allowing on-machine positioning between 0 and 50 mm without shims. This SKU includes a male M22x1.5 piston rod thread (option B) and lacks a piston magnet, so it cannot use reed or electronic switches.
