Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X100-100B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X100-100B is a genuine double-acting COMPACT cylinder (Ø40mm bore) whose extend end-position is set by an external M12×1.25 adjustment screw. You can dial the stroke anywhere from 0 to 100 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X100-100B
The AirTAC SDAJ40X100-100B is a double-acting compact cylinder featuring a male-thread M14x1.5 piston rod and an external extend stop. By turning the R (M12x1.25) adjuster screw, you can dial the outward stroke down from the 100mm maximum all the way to zero directly on the machine, eliminating the need for shims or part swaps. Because the adjuster only sets the mechanical stop and not the piston area, output force remains identical to a standard SDA of this bore, delivering 628.3 N of push at 0.5 MPa.
The short riveted body drastically reduces axial mounting depth, fitting where round-body or profile cylinders cannot. End-of-travel shock is handled by a fixed NBR bumper that decelerates the piston, rather than an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot support reed or electronic switches; adding an -S variant is required for position sensing.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X100-100B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Max stroke | 100 mm |
| Adjustable range | 0 – 100 mm |
| Adjuster thread (R) | M12×1.25 |
| Port size | PT1/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M8×1.25 F / M14×1.5 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 100 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X100-100B Is Used
Adjustable Tooling Stops
Dial in the exact extend position from 0 to 100mm during machine changeover using the M12x1.25 screw, perfect for accommodating multiple part heights on a single 628.3 N push station.
Vertical Lift Fixtures
Lift up to 32 kg with a 2:1 safety margin at 0.5 MPa, relying on the male M14x1.5 rod for secure tool mounting while fine-tuning the upward travel limit on the fly.
Trial Positioning Rigs
Set precise extend endpoints during prototype development without disassembling the line, leveraging the compact riveted body to save axial space in tight rigging envelopes.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X100-100B the Right Cylinder?
When sizing this 40mm bore, evaluate your neighbors: dropping down to an SDAJ32 provides 402.1 N of push at 0.5 MPa, while stepping up to an SDAJ50 yields 981.7 N. The 628.3 N output at 0.5 MPa translates to a safe working load of roughly 377 N (about 60 percent of capacity) and a vertical lift capability near 32 kg with a 2:1 safety margin. Choose this 100mm window model if your fixture requires extensive on-site tuning or trial positioning across the full zero to 100mm range.
Confirm your parameters: 40mm bore, 100mm stroke, 100mm adjust window, PT1/8 port, male M14x1.5 rod thread, and no magnet. Note that a plain SDAJ does not hold position or load when air is lost or the valve is centered; the fixed bumper only decelerates near the end, and the adjuster is a mechanical stop, not a lock. For load holding 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 0–100 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 M12×1.25 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 SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X100-100B FAQ
This 40mm bore cylinder features a PT1/8 air port and delivers 628.3 N push / 527.8 N pull at 0.5 MPa, 879.6 N push / 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128 kgf at 1.0 MPa.
Turning the R (M12x1.25) screw mechanically shortens the extend stop from 100mm down to 0mm without changing the force. This specific -B SKU lacks a piston magnet, so it cannot take a switch; you must select an -S variant to use AirTAC reed or electronic sensors.
