Airtac B01-SDAJ Special Cylinder B01-SDAJ32X75-75S
The AirTAC Airtac B01-SDAJ Special Cylinder B01-SDAJ32X75-75S 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 B01-SDAJ Special Cylinder B01-SDAJ32X75-75S
The AirTAC B01-SDAJ32X75-75S is a double-acting compact cylinder featuring an external adjustable extend stop. The B01- prefix marks this as an application-dedicated, customer-specified variant of the base SDAJ32X75-75S; mechanically, every physical spec is identical. A simple turn of the R (M10x1.25) adjuster screw lets you dial the extend position from 0 to 75 mm directly on the machine, eliminating the need for shims or part swaps during changeovers.
Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains equal to a standard SDA of this bore, delivering about 402.1 N of push at 0.5 MPa. The short riveted body saves valuable axial mounting depth where a larger profile cylinder will not fit. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the piston, and the built-in magnet (-S) supports AirTAC reed or electronic solid-state switches for position sensing.

| Model | Airtac B01-SDAJ Special Cylinder B01-SDAJ32X75-75S |
|---|---|
| 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 B01-SDAJ Special Cylinder B01-SDAJ32X75-75S Is Used
Custom Tooling Setup
Dial the extend stop from 0 to 75 mm on the fly to test multiple probe depths during initial fixture commissioning without machining new spacers.
Changeover Positioning
Quickly reposition the 402.1 N push point for different product families on a packaging line, relying on the M10x1.25 adjuster for exact mechanical stops.
Vertical Lift Testing
Safely trial vertical lifts up to 20.5 kg with a 2:1 margin, adjusting the extend endpoint to prevent overtravel while evaluating a new assembly process.
Is the Airtac B01-SDAJ Special Cylinder B01-SDAJ32X75-75S the Right Cylinder?
When sizing this 32 mm bore, compare its 402.1 N push at 0.5 MPa against neighbouring bores: stepping down to an SDAJ25 yields 245.4 N, while moving up to an SDAJ40 provides 628.3 N. Based on the 402.1 N figure, a safe working load is approximately 241 N (about 60 percent capacity), translating to a vertical lift capability of roughly 20.5 kg with a 2:1 safety margin. Choose this unit if your fixture requires frequent on-machine stroke tuning across the full 0-75 mm window.
Confirm the required bore, 75 mm maximum stroke, 75 mm adjustability window, PT1/8 port, and the built-in magnet (S) for switch integration. Note that a plain cylinder does not hold its load if air pressure is lost or the valve is centred, as the fixed bumper only decelerates near the end of travel 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 0–75 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 B01-SDAJ Special Cylinder B01-SDAJ32X75-75S 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.
The B01- prefix simply designates an application-dedicated variant of the SDAJ32X75-75S with identical mechanics. The R (M10x1.25) screw shortens the extend stop by up to 75 mm (usable range 0-75 mm); it sets the stop position without changing the force, and the built-in magnet works with AirTAC reed or electronic switches.
