Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X55-10B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X55-10B is a genuine double-acting COMPACT cylinder (Ø32mm bore) whose extend end-position is set by an external M10×1.25 adjustment screw. You can dial the stroke anywhere from 45 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X55-10B
The AirTAC SDAJ32X55-10B is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. A front R screw (M10x1.25) lets you dial the forward end-position on the machine, yielding a usable extend range of 45 to 55 mm without swapping shims or components. Because the adjuster merely sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering about 402.1 N push at 0.5 MPa.
This variant utilizes a male-threaded piston rod (M10x1.25) for direct fixture mounting and carries no piston magnet, meaning magnetic switches cannot be fitted to this specific SKU. The short riveted body saves valuable axial mounting depth where a larger profile cylinder would fail to fit. End-of-travel deceleration is handled strictly by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion or a locking brake.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X55-10B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 55 mm |
| Adjustable range | 45 – 55 mm |
| Adjuster thread (R) | M10×1.25 |
| Port size | PT1/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M6×1.0 F / M10×1.25 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 10 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SDAJ32X55-10B Is Used
Tooling Depth Calibration
Dial in the exact 45 to 55 mm extend stop during initial setup to perfect part clamping depth without machining custom spacers.
Product Changeover
Quickly reposition the male M10x1.25 rod end on a packaging line when switching to a different carton size, saving valuable changeover minutes.
Trial Positioning
Safely test end-of-stroke locations for a new assembly process, relying on the 402.1 N push force to seat components before locking the final design.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X55-10B the Right Cylinder?
When sizing this 32 mm bore, evaluate both neighboring options. Stepping down to an SDAJ25 yields 245.4 N push at 0.5 MPa, whereas stepping up to an SDAJ40 provides 628.3 N push at 0.5 MPa. Based on the 402.1 N push figure, a safe working load is approximately 241 N (using a 60% margin), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety factor. Choose this male-rod (-B) model if your tooling requires a threaded attachment point, and utilize the 10 mm adjust window for trial positioning or rapid machine changeovers.
Remember that a plain SDAJ does not hold position or carry loads if air pressure drops or the valve centers; the piston will drift. The fixed NBR bumper only decelerates the stroke near its end and the R screw is a mechanical stop, neither function as a brake. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your requirements for the PT1/8 port, 55 mm maximum stroke, 10 mm window, and the lack of a sensing magnet before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–55 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 M10×1.25 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 SDAJ32X55-10B FAQ
This 32 mm bore double-acting cylinder delivers 402.1 N push and 345.6 N pull at 0.5 MPa, and 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum push force is 82 kgf at 1.0 MPa.
The external M10x1.25 R screw acts as a mechanical stop, allowing you to shorten the extend stroke by up to 10 mm on-site, giving a usable range of 45 to 55 mm. It does not alter the pneumatic force or lock the piston mid-stroke.
