Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30B is a genuine double-acting COMPACT cylinder (Ø100mm bore) whose extend end-position is set by an external M27×2.0 adjustment screw. You can dial the stroke anywhere from 10 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30B
The AirTAC SDAJ100X40-30B is a double-acting compact cylinder featuring an external adjustable extend stop. A M27x2.0 adjuster screw lets you dial the outward stroke from 10 to 40 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Retract travel remains full length.
This 100 mm bore unit delivers 3927 N of push force at 0.5 MPa, exactly matching a standard SDA of this size because the adjuster sets the mechanical stop, not the piston area. The short riveted body drastically reduces axial mounting depth where a larger profile cylinder will not fit. It includes a male M26x1.5 piston rod thread and relies on a fixed NBR bumper to decelerate the end of travel.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 40 mm |
| Adjustable range | 10 – 40 mm |
| Adjuster thread (R) | M27×2.0 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M18×1.5 F / M26×1.5 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 30 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3525 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30B Is Used
Press Fit Tuning
Dial the extend stop from 10 to 40 mm to set precise contact depth on heavy bearing press tasks without swapping mechanical spacers.
Heavy Clamping Changeover
Leverage the 3927 N push at 0.5 MPa to secure large fixtures, adjusting the outward reach on-site for varied part geometries.
Vertical Lift Positioning
Safely lift loads up to 200.2 kg with a 2:1 margin, using the external screw to fine-tune the raise height before the fixed bumper stops the move.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30B the Right Cylinder?
When sizing this model, evaluate both directions: stepping down to the SDAJ80 yields 2513.3 N of push at 0.5 MPa, while this 100 mm bore provides 3927 N. A computed safe working load is approximately 2356 N, offering a 2:1 vertical lift margin of about 200.2 kg. Choose the 100 mm bore when your setup-heavy lines require that extra thrust for pressing or clamping.
This SKU specifies a 40 mm maximum stroke with a 30 mm adjust window, a PT3/8 port, and a male M26x1.5 rod thread. It lacks the -S magnet option, so it cannot accept reed or electronic switches. Note that a plain cylinder does not hold position on air loss; for load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–40 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 M27×2.0 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 SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30B FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa.
The M27x2.0 screw mechanically limits the extend stroke, allowing you to set the outward stop anywhere between 10 and 40 mm. It does not alter the 3927 N force output and is not a mid-stroke lock.
