Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30S 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 25 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30S
The AirTAC SDAJ80X55-30S is a compact double-acting single-rod cylinder engineered for high-force applications where the extend end-position must be dialed in on the machine. An external M20x1.5 adjuster screw lets you shorten the extend stroke anywhere between 25 and 55 mm without swapping shims or parts. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, yielding 2513.3 N of push at 0.5 MPa.
This 80 mm bore unit features a space-saving riveted body that minimizes axial mounting depth in tight fixtures. It carries a built-in piston magnet for AirTAC reed or electronic switches, while a fixed NBR bumper at each end decelerates the stroke end. The bore dictates a PT3/8 air port and a 25 mm rod diameter to handle substantial loads.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 55 mm |
| Adjustable range | 25 – 55 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 SDAJ80X55-30S Is Used
Heavy Press Fitments
Dialing the extend stop down to 25 mm prevents over-travel when seating heavy bearings, leveraging the 2513.3 N push for consistent assembly depth.
Automated Changeovers
Quickly reposition the rod end between 25 and 55 mm on packaging lines to accommodate different product sizes without changing cylinder hardware.
Vertical Lift Stops
Set precise upper travel limits for elevators handling loads up to 128.1 kg, using the M20x1.5 screw to fine-tune the mechanical stop safely.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30S the Right Cylinder?
When sizing this model, compare its 2513.3 N push at 0.5 MPa against adjacent bores: an SDAJ63 provides 1558.6 N, whereas an SDAJ100 delivers 3927 N. This SDAJ80X55-30S fits scenarios demanding heavy thrust with on-site stroke tuning. Based on its 0.5 MPa output, a safe working load is roughly 1508 N (about 60 percent of capacity), translating to a vertical lift capability near 128.1 kg with a 2:1 safety margin.
Operators needing frequent changeover or trial positioning will benefit from the 30 mm adjustment window. Remember that a plain compact cylinder does not hold position if air pressure drops or the valve centers; the piston drifts and the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your bore, 55 mm maximum stroke, 30 mm window, PT3/8 port, built-in magnet, and female rod-end thread.

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 SDAJ80X55-30S FAQ
This 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 of 513 kgf at 1.0 MPa.
The M20x1.5 screw shortens the extend stop within a 25-55 mm window without altering force. The included -S magnet works with AirTAC reed or electronic switches for position sensing, while a fixed NBR bumper handles end deceleration.
