Airtac B01-SDAJ Special Cylinder B01-SDAJ63X80-40S
The AirTAC Airtac B01-SDAJ Special Cylinder B01-SDAJ63X80-40S is a genuine double-acting COMPACT cylinder (Ø63mm bore) whose extend end-position is set by an external M16×1.5 adjustment screw. You can dial the stroke anywhere from 40 to 80 mm on the machine — no shims, no part change.

About the Airtac B01-SDAJ Special Cylinder B01-SDAJ63X80-40S
The AirTAC B01-SDAJ63X80-40S is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. The leading B01- prefix marks this as an application-dedicated, customer-specified variant of the base SDAJ63X80-40S; mechanically, every physical spec is identical. A PT1/4 port feeds the 63mm bore, generating 1558.6 N of push force at 0.5 MPa.
By turning the R (M16x1.5) adjuster screw, you set the extend end-position anywhere between 40 and 80 mm directly on the machine without changing parts. The short riveted body saves axial mounting depth where round-body or profile cylinders will not fit. This unit includes a built-in piston magnet (-S) for AirTAC reed or electronic switches, while a fixed NBR bumper decelerates the stroke end.

| Model | Airtac B01-SDAJ Special Cylinder B01-SDAJ63X80-40S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø63 mm |
| Max stroke | 80 mm |
| Adjustable range | 40 – 80 mm |
| Adjuster thread (R) | M16×1.5 |
| Port size | PT1/4 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M10×1.5 F / M18×1.5 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 40 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 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-SDAJ63X80-40S Is Used
Custom Machine Tooling
Dial the extend stop from 40 to 80 mm via the M16x1.5 screw to set exact clamping depth on dedicated machining heads without fabricating new spacers.
Changeover-Heavy Lines
Rapidly reposition the 1558.6 N push stroke for different product sizes, using the external adjuster to cut setup time during format changeovers.
Vertical Lift Stations
Lift loads up to 79.4 kg with a 2:1 safety margin, tweaking the extend endpoint on-site to accommodate varying package heights.
Is the Airtac B01-SDAJ Special Cylinder B01-SDAJ63X80-40S the Right Cylinder?
Sizing this 63mm bore requires checking both neighbours. Stepping down, the SDAJ50 provides 981.7 N push at 0.5 MPa; stepping up, the SDAJ80 yields 2513.3 N. This B01-dedicated model hits 1558.6 N, offering a safe working load around 935 N (roughly 60 percent of the 0.5 MPa figure) and a vertical lift capacity near 79.4 kg with a 2:1 margin. Choose it when you need on-site stroke tuning between 40 and 80 mm.
Confirm the 63mm bore, 80mm max stroke, 40mm window, PT1/4 port, female M10x1.5 rod thread, and the -S magnet. Remember that a plain cylinder does not hold its load on air loss or when the valve is centred; the piston drifts and the bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 40–80 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 M16×1.5 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-SDAJ63X80-40S FAQ
This application-dedicated variant matches the base SDAJ63X80-40S exactly. It delivers 1558.6 N push and 1401.5 N pull at 0.5 MPa, 2182.1 N push and 1962.2 N pull at 0.7 MPa, with a theoretical max of 318 kgf at 1.0 MPa. The 63mm bore uses a PT1/4 port and operates at 30-500 mm/s.
The R (M16x1.5) screw shortens the extend stop by up to 40 mm, giving a usable extend range of 40-80 mm; retract remains full. The screw sets the mechanical stop position and does not change force. The built-in -S magnet works with AirTAC reed or electronic solid-state switches for position sensing.
