About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-40
The AirTAC SDAJ80X40-40 is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. An M20x1.5 adjuster screw lets you dial the extend position from 0 to 40 mm directly on the machine, delivering 2513.3 N of push force at 0.5 MPa without altering the piston area. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit.
This 80 mm bore unit relies on a fixed NBR bumper to decelerate the stroke end rather than an adjustable air cushion. It operates at speeds between 30 and 500 mm/s, and because this SKU lacks the -S magnet option, it cannot host reed or electronic switches.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 40 mm |
| Adjustable range | 0 – 40 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 40 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 SDAJ80X40-40 Is Used
Heavy Press Fitment
Dial the 0-40 mm extend stop during setup to precisely seat heavy bearings, utilizing the 2513.3 N push force without exceeding target depth.
Bulk Item Diversion
Adjust the extend length on-site to deflect varying package sizes on a packaging line, ensuring positive contact without redesigning mounts.
Pallet Lift Positioning
Fine-tune the lifting height of heavy pallets in confined spaces, where the short riveted body provides necessary clearance and high force.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-40 the Right Cylinder?
When sizing this unit, compare its 2513.3 N push at 0.5 MPa against neighbouring bores: an SDAJ63 provides 1558.6 N, while an SDAJ100 yields 3927 N. Choose this 80 mm model when your changeover process demands heavy on-site stroke tuning between 0 and 40 mm. Confirm your requirements for bore, stroke, window, PT3/8 port, and the female M14x1.5 rod thread.
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 acts as a mechanical stop, not a lock. 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 0–40 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 SDAJ80X40-40 FAQ
This 80 mm bore double-acting cylinder provides 2513.3 N push and 2267.8 N pull at 0.5 MPa, 3518.6 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum push of 513 kgf at 1.0 MPa.
Turning the M20x1.5 R screw shortens the extend stop by up to 40 mm, allowing usable extend positions from 0 to 40 mm. The retract stroke remains full, and the adjuster sets the stop position without changing the force.
