Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-10B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-10B 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 30 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-10B
The AirTAC SDAJ100X40-10B is a double-acting compact cylinder featuring an external R (M27x2.0) adjuster screw that dials the extend stop from 30 to 40 mm directly on your machine. Because the mechanism sets the mechanical stop rather than altering the piston area, output force equals a standard SDA of this bore, yielding 3927 N of push at 0.5 MPa.
The short riveted body saves valuable axial mounting depth where larger profile or round-body units fail to fit. This specific SKU uses a male-thread M26x1.5 piston rod and lacks a piston magnet, meaning it cannot accept reed or electronic switches without switching to the -S variant. End shock is managed solely by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 40 mm |
| Adjustable range | 30 – 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 10 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 SDAJ100X40-10B Is Used
Heavy Press Fitment
Dial the 30-40 mm extend stop during machine commissioning to achieve the exact contact force for heavy press operations without changing parts.
Short-Depth Clamping
Leverage the compact riveted body to fit high-force 3927 N clamping into tight machinery frames where axial length is severely restricted.
Changeover Positioning
Adjust the mechanical stop on-site for rapid product changeovers, using the male M26x1.5 rod to secure heavy tooling plates accurately.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-10B the Right Cylinder?
When sizing this unit, evaluate both neighbors: stepping down to an SDAJ80 provides 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore delivers 3927 N. Based on the 0.5 MPa figure, a safe working load is roughly 2356 N (about 60 percent of capacity), translating to a vertical lift of approximately 200.2 kg with a 2:1 safety margin.
Operators needing on-site stroke tuning for trial positioning will benefit from the 10 mm adjust window. Remember that a plain SDAJ does not hold position or load when air is lost or the valve is centered; the fixed bumper only decelerates near the end, so employ an external rod lock or pilot-operated check valve for load holding. Confirm your bore, 40 mm stroke, 10 mm window, PT3/8 port, lack of magnet, and male M26x1.5 rod thread before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–40 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 SDAJ100X40-10B FAQ
This 100 mm bore double-acting cylinder uses a PT3/8 port. It generates 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.
Turning the R (M27x2.0) screw shortens the extend stroke by up to 10 mm, giving a usable range of 30-40 mm. The screw is a mechanical stop, not a mid-stroke lock; the cylinder will drift if air is lost, so use an external rod lock for load holding.
