Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30 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 15 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30
The AirTAC SDAJ80X45-30 is a double-acting compact cylinder featuring an external adjustable extend stop. A simple turn of the R (M20x1.5) screw lets you dial the outward stroke down on the machine, yielding a usable extension range of 15 to 45 mm without swapping shims or parts. Because the mechanism merely sets the mechanical end position, output remains identical to a standard 80 mm bore, providing 2513.3 N of push force at 0.5 MPa.
Built with a short riveted body, this unit saves significant axial mounting depth where a larger profile or round-body actuator would never fit. End-of-travel energy is managed strictly by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to an -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 45 mm |
| Adjustable range | 15 – 45 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 30 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 SDAJ80X45-30 Is Used
Press Fit Tuning
Dial in the exact 15-45 mm insertion depth for heavy bearing press fits, leveraging the 2513.3 N push force to seat components without over-traveling.
Heavy Diverter Setup
Adjust the extend stop on-site to accommodate different pallet widths on a packaging line, using the fixed NBR bumper to absorb the kinetic energy of the 25 mm rod.
Vertical Lift Stops
Set precise mechanical lower limits for lifting 128.1 kg loads, ensuring the actuator halts exactly where needed while relying on external checks for load holding.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30 the Right Cylinder?
When sizing this 80 mm bore, evaluate your neighbours: stepping down to the SDAJ63 yields 1558.6 N of push at 0.5 MPa, while stepping up to the SDAJ100 provides 3927 N. This SDAJ80X45-30 sits comfortably in between, delivering a safe working load of roughly 1508 N (about 60% of its 0.5 MPa rating) and a vertical lift capacity of 128.1 kg with a 2:1 safety margin. It is ideal for heavy fixtures requiring frequent on-site stroke tuning during changeovers.
Confirm your parameters: 80 mm bore, 45 mm maximum stroke, 30 mm adjust window, PT3/8 port, female M14x1.5 rod thread, and no magnet. Remember that a plain double-acting cylinder does not hold position if air pressure drops or the valve centers—the piston will drift. For suspended or vertical loads that must remain fixed without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–45 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 SDAJ80X45-30 FAQ
This 80 mm bore double-acting cylinder has a PT3/8 air port. It generates 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.
The external M20x1.5 screw acts as a mechanical stop, allowing you to shorten the extend stroke anywhere between 15 and 45 mm. It does not alter the output force, nor does it lock the piston mid-stroke; the cylinder still requires air pressure to move and hold.
