Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-40SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-40SB 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 25 to 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-40SB
The SDAJ100X65-40SB is a 100 mm bore double-acting compact cylinder with an external extend stop. Turning the R (M27x2.0) screw lets you dial the outward stroke anywhere from 25 to 65 mm directly on the machine. Because the adjuster sets the mechanical stop rather than the piston area, output matches a standard SDA at 3927 N push at 0.5 MPa. This specific build includes a male M26x1.5 piston rod (-B) and a built-in magnet (-S) for position sensing.
Its short riveted body saves axial mounting depth where a larger profile cylinder will not fit. End shock is handled by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion. Operating speed spans 30-500 mm/s, and the PT3/8 air port supplies the 32 mm diameter rod.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 65 mm |
| Adjustable range | 25 – 65 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 40 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 SDAJ100X65-40SB Is Used
Heavy Press Fit Setup
Dial the 25-65 mm extend stop to test bearing seating depth on heavy press lines, avoiding part changes during trial positioning.
Vertical Lift Dampening
Lift 200.2 kg loads with a 2:1 safety margin, relying on the fixed NBR bumper to absorb end shock at the bottom of the travel.
Multi-Product Changeover
Turn the M27x2.0 adjuster screw to quickly reset the extend position when switching between product sizes on a shared fixture.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-40SB the Right Cylinder?
This 100 mm bore delivers 3927 N push at 0.5 MPa, yielding a safe working load around 2356 N (about 60 percent of capacity) and a vertical lift capability of roughly 200.2 kg with a 2:1 margin. If your application requires less force, the smaller SDAJ80 provides 2513.3 N push at 0.5 MPa. Since 100 mm is the largest standard SDAJ bore, moving up in AirTAC size requires a different series. Choose this unit when you need on-site stroke tuning during frequent changeovers. It features a male M26x1.5 rod thread and a magnet for 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 25–65 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 SDAJ100X65-40SB FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. At 0.7 MPa it provides 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The external R (M27x2.0) screw shortens the extend stop by up to 40 mm, giving a usable range of 25-65 mm. The included -S magnet works with AirTAC reed or electronic switches for end-position sensing.
