Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-50B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-50B 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 35 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-50B
The AirTAC SDAJ32X85-50B is a double-acting compact cylinder featuring a male-thread piston rod and an external extend stop. A built-in M10x1.25 adjuster screw lets you dial the extend position anywhere between 35 and 85 mm directly on your equipment, eliminating the need for shims or part swaps during changeovers. Retract travel remains full length.
Because the adjuster only sets the mechanical stop, output force matches a standard SDA of this bore, delivering 402.1 N push at 0.5 MPa. The short riveted body minimizes axial mounting depth where space is tight. End shock is handled by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 85 mm |
| Adjustable range | 35 – 85 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 50 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 SDAJ32X85-50B Is Used
Machine Tending Setup
Dial in the exact 35-85 mm extend reach for varying part sizes during machine tending changeovers without machining new spacers.
Carton Forming Stops
Set precise mechanical end positions for folding flaps on different carton depths, relying on the 402.1 N push force at 0.5 MPa.
Press Fit Positioning
Trial-fit bearings or pins by adjusting the M10x1.25 screw on-site to find the perfect depth before locking down the cycle.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-50B the Right Cylinder?
Choosing this 32 mm bore gives 402.1 N push at 0.5 MPa. If you need less force, the smaller SDAJ25 provides 245.4 N, while stepping up to the SDAJ40 yields 628.3 N. A practical safe working load is roughly 241 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 20.5 kg with a 2:1 safety margin.
This SKU includes a male M10x1.25 rod thread and lacks a piston magnet, so it cannot accept reed or electronic switches. Note that a plain cylinder does not hold position if air pressure drops or the valve centers; the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, install an external rod lock or pilot-operated check valve. Confirm your required 35-85 mm adjust window, PT1/8 port, and 30-500 mm/s speed range fit the application.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–85 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 SDAJ32X85-50B FAQ
This 32 mm bore double-acting cylinder delivers 402.1 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum push of 82 kgf at 1.0 MPa.
Turning the R (M10x1.25) screw mechanically shortens the extend stroke by up to 50 mm, giving a usable range of 35 to 85 mm. It sets the stop position only and does not alter force or lock the piston mid-stroke.
