Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40SB 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 SDAJ80X35-40SB
The AirTAC SDAJ80X35-40SB is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M20x1.5) screw, you can dial the extend position from 0 up to 35 mm directly on the machine, avoiding part swaps. Because the adjuster sets the mechanical stop rather than the piston area, output force equals a standard SDA of this bore, yielding 2513.3 N push at 0.5 MPa.
This variant includes a built-in piston magnet for AirTAC reed or electronic switches and a male-thread piston rod (M22x1.5). Its short riveted body saves axial mounting depth where round-body or profile cylinders will not fit. End shock is managed 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 SDAJ80X35-40SB |
|---|---|
| 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 SDAJ80X35-40SB Is Used
Press Fit Dial-In
Turn the M20x1.5 screw to set the extend stop between 0 and 35 mm, hitting exact press depths for 128.1 kg vertical lifts without machining new spacers.
High-Force Changeover
Leverage the 2513.3 N push at 0.5 MPa to shift heavy pallets, adjusting the male M22x1.5 rod end contact point on the fly for varying product widths.
Vertical Lift Dampening
Raise 1508 N loads safely, relying on the fixed NBR bumper to decelerate the stroke end while the compact riveted body minimizes vertical headspace.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X35-40SB the Right Cylinder?
When sizing this 80 mm bore, compare it both ways: stepping down to SDAJ63 provides 1558.6 N push at 0.5 MPa, while stepping up to SDAJ100 delivers 3927 N. This model provides a safe working load of roughly 1508 N (about 60 percent of its 0.5 MPa rating) and can vertically lift approximately 128.1 kg with a 2:1 margin. Choose this unit if your fixture requires on-site stroke tuning during changeovers.
Confirm the 80 mm bore, 35 mm stroke, 40 mm adjustment window, and PT3/8 port suit your pneumatic layout. This specific SKU includes the -S magnet for position sensing and the -B male M22x1.5 rod end. Note that a plain cylinder does not hold its load on air loss or valve centering; the piston drifts and the bumper only decelerates near the end. For a held load, specify 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 SDAJ80X35-40SB FAQ
This 80 mm bore cylinder delivers 2513.3 N push and 2267.8 N pull at 0.5 MPa. At 0.7 MPa, push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push is 513 kgf at 1.0 MPa.
The R (M20x1.5) screw shortens the extend stop by up to 40 mm, providing a usable extend range of 0-35 mm. The -S code indicates a built-in piston magnet compatible with AirTAC reed or electronic switches for position sensing.
