Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40 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 SDAJ80X35-40
The AirTAC SDAJ80X35-40 is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. An M20x1.5 adjuster screw lets you dial the outward stroke from 0 to 35 mm directly on the machine, completely removing the need for shims or part swaps during setup. Because the screw only sets the mechanical stop position, the output force remains identical to a standard SDA of this bore, delivering 2513.3 N of push at 0.5 MPa.
This 80 mm bore unit saves substantial axial mounting depth thanks to its short riveted body, fitting where larger profile cylinders cannot. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40 |
|---|---|
| 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 SDAJ80X35-40 Is Used
Heavy Press Fit Tuning
Dial in the exact 0-35 mm extend stop during heavy press-fit changeovers, leveraging the 2513.3 N push force without swapping mechanical spacers.
Vertical Lift Positioning
Set precise downward travel for a 128.1 kg vertical lift payload, using the M20x1.5 adjuster to find the perfect resting height on-site.
Compact High-Force Clamping
Fit high-force clamping into tight machine footprints using the short riveted body, adjusting the jaw opening between 0 and 35 mm as material thicknesses vary.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40 the Right Cylinder?
When sizing this model, look at both neighbours: the 63 mm bore provides 1558.6 N of push at 0.5 MPa, whereas the 100 mm bore yields 3927 N. The SDAJ80X35-40 sits comfortably in the middle, delivering 2513.3 N push and 2267.8 N pull at 0.5 MPa, which translates to a safe working load of roughly 1508 N or a vertical lift capacity of about 128.1 kg with a 2:1 safety margin. Choose this 80 mm bore if your changeover process requires frequent, on-site extend tuning between 0 and 35 mm.
Confirm your parameters: an 80 mm bore, a 35 mm maximum stroke with a 40 mm adjustment window, and a PT3/8 air port. This configuration has a female M14x1.5 rod-end thread and no magnet. Because the fixed NBR bumper only decelerates the stroke end and the adjuster acts as a mechanical stop rather than a lock, the piston will drift if air is lost or the valve is centred. To hold a load securely 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 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 SDAJ80X35-40 FAQ
This 80 mm bore cylinder features a PT3/8 air port. It 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 push of 513 kgf at 1.0 MPa.
The M20x1.5 adjuster screw shortens the extend stroke by up to 40 mm, allowing you to set the outward stop anywhere between 0 and 35 mm. This specific SKU has no piston magnet, so it cannot take a magnetic switch; you would need the -S option for reed or electronic sensing.
