Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30B 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 5 to 35 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30B
The AirTAC SDAJ80X35-30B is a compact double-acting single-rod cylinder featuring an external extend stop. An M20x1.5 adjuster screw lets you dial the extend position down from the 35 mm maximum to 5 mm directly on the machine, avoiding part swaps. Because the adjuster restricts travel rather than piston area, output matches a standard 80 mm bore at 2513.3 N push at 0.5 MPa.
Built with a short riveted body, this unit saves axial mounting depth where round-body alternatives will not fit. It uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. This SKU includes a male M22x1.5 rod end and lacks a piston magnet, so it cannot host reed or electronic switches.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30B Technical Specifications
| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 35 mm |
| Adjustable range | 5 – 35 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 SDAJ80X35-30B Is Used
Press Fit Dial-In
Use the 5-35 mm extend window to fine-tune the pressing depth of 128.1 kg assemblies during setup, ensuring exact seating without machining new spacers.
Carton Flap Folding
Adjust the male M22x1.5 rod stop on the fly to accommodate varying box heights, using the 2513.3 N force to fold heavy cardboard flaps cleanly.
Pallet Positioning
Dial the extend stop down to 5 mm for low-profile pallets, leveraging the short riveted body to fit tight vertical clamping spaces under the conveyor.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-30B the Right Cylinder?
When sizing this 80 mm bore, consider the neighbours: stepping down to SDAJ63 yields 1558.6 N push at 0.5 MPa, while stepping up to SDAJ100 provides 3927 N. The 80 mm bore delivers 2513.3 N push at 0.5 MPa, translating to a safe working load of roughly 1508 N or a vertical lift of 128.1 kg with a 2:1 margin.
Choose this specific configuration if your fixture requires on-site extend tuning between 5 and 35 mm and a male M22x1.5 rod thread. Note that a plain cylinder does not hold its load on air loss or valve centring—the piston drifts and the fixed bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or pilot-operated check valve. Confirm your requirements for the PT3/8 port, 30 mm window, and absence of a magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–35 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 SDAJ80X35-30B FAQ
This 80 mm bore cylinder delivers 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 stroke from 35 mm down to 5 mm; it sets the mechanical stop and does not alter force. It is not a mid-stroke lock, and the cylinder cannot hold a load without live air pressure.
