Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40B 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 35 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40B
The AirTAC SDAJ80X35-40B is a double-acting compact cylinder featuring a male-thread piston rod (M22x1.5) and an external adjustable extend stop. Turning the M20x1.5 R screw lets you dial the extend position from 0 to 35 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Retract travel remains full length.
This 80 mm bore unit delivers 2513.3 N of push force at 0.5 MPa, identical to a standard SDA because the adjuster sets the mechanical stop, not the piston area. The short riveted body saves axial mounting depth where round-body or profile cylinders will not fit. End shock is handled by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 35 mm |
| Adjustable range | 0 – 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 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 SDAJ80X35-40B Is Used
Press Fit Tuning
Dial the extend stop from 0 to 35 mm on the factory floor to set precise pressing depths for 80 mm bore assemblies without machining new spacers.
Changeover Adjustment
Quickly reposition the male M22x1.5 rod end for varying product lengths on a packaging line, relying on the 2513.3 N push force to shift heavy loads.
Vertical Lift Setup
Lift payloads up to 128.1 kg with a 2:1 safety margin, using the M20x1.5 adjuster screw to set the exact raise height and prevent overtravel.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40B the Right Cylinder?
When sizing this model, evaluate both neighbouring bores: the SDAJ63 provides 1558.6 N push at 0.5 MPa, while the SDAJ100 offers 3927 N. This SDAJ80X35-40B sits in the middle with 2513.3 N, yielding a safe working load of roughly 1508 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity near 128.1 kg with a 2:1 margin.
Choose this specific configuration if your fixture requires on-site stroke tuning for trial positioning. Confirm the 80 mm bore, 35 mm stroke, 40 mm window, PT3/8 port, and male M22x1.5 rod thread suit your tooling. Note that a plain cylinder does not hold a load on air loss or valve centring; the piston drifts and the fixed bumper only decelerates near the end. For secure load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–35 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 SDAJ80X35-40B FAQ
This 80 mm bore double-acting cylinder uses 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 of 513 kgf at 1.0 MPa.
No, this specific SKU lacks the -S option and has no piston magnet, so it cannot accept reed or electronic switches. You must select the -S variant to enable sensing capabilities alongside the mechanical stop adjustment.
