Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-75B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-75B 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 0 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-75B
The AirTAC SDAJ32X75-75B is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. By turning the R (M10x1.25) screw, you can dial the extend position from 0 to 75 mm directly on the machine, eliminating the need for shims or part swaps. The short riveted body saves valuable axial mounting depth where a larger profile cylinder will not fit.
Because the adjuster sets the mechanical stop rather than the piston area, force remains identical to a standard SDA of this bore, delivering about 402.1 N of push at 0.5 MPa. This specific SKU includes a male-threaded M10x1.25 piston rod and lacks a piston magnet, meaning it cannot accept reed or electronic switches without changing to an -S variant. End-of-travel deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-75B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 75 mm |
| Adjustable range | 0 – 75 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 75 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 SDAJ32X75-75B Is Used
Tooling Changeover
Dial the extend stop from 0 to 75 mm via the R screw during fixture swaps, ensuring the 402.1 N push thrust meets varying part heights without machining new spacers.
Trial Positioning
Perfect for prototype assembly stations where the exact extend point is unknown; use the male M10x1.25 rod to mount probes and fine-tune the stop on the fly.
Compact Clamping
Fit the short riveted body into tight machine cells to clamp workpieces, relying on the fixed NBR bumper to absorb the shock of each 20.5 kg vertical clamping cycle.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-75B the Right Cylinder?
When sizing this 32 mm bore, compare your thrust requirements both ways: stepping down to an SDAJ25 yields 245.4 N of push at 0.5 MPa, while stepping up to an SDAJ40 provides 628.3 N. Based on the 402.1 N output at 0.5 MPa, a safe working load is approximately 241 N (60% capacity), translating to a vertical lift capability of roughly 20.5 kg with a 2:1 safety margin. Choose this model if your fixture changeovers demand frequent on-site stroke tuning between 0 and 75 mm.
Confirm the bore (32 mm), maximum stroke (75 mm), adjustment window (75 mm), and PT1/8 air port match your manifold. This unit features the -B male M10x1.25 rod end for external mounting nuts. Remember that a plain SDAJ does not hold position or load when air is lost or the valve is centred; the fixed bumper only decelerates near the end of travel. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–75 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 SDAJ32X75-75B FAQ
This 32 mm bore cylinder delivers 402.1 N push and 345.6 N pull at 0.5 MPa, and 563 N push at 0.7 MPa. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, with a speed range of 30-500 mm/s and a temperature range of -20 to +70 C.
Turning the M10x1.25 R screw shortens the extend stroke by up to 75 mm, allowing usable extend positions between 0 and 75 mm while retract remains full. This SKU has no piston magnet and cannot take a switch; you would need the -S variant to use AirTAC reed or electronic sensors.
