Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-20S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-20S 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 80 to 100 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-20S
The AirTAC SDAJ100X100-20S is a compact double-acting single-rod cylinder engineered for heavy-duty positioning where axial mounting depth is restricted. Its short riveted body saves space while delivering substantial force, yielding about 3927 N of push at 0.5 MPa. An external M27x2.0 adjustment screw allows you to dial the extend stop down from the 100 mm maximum to 80 mm directly on the machine, eliminating the need for shims or part swaps during changeovers.
This 100 mm bore unit features a 32 mm piston rod and a PT3/8 air port. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this size. The -S suffix indicates a built-in piston magnet for AirTAC reed or electronic switches. End-of-travel shock is managed by a fixed NBR bumper, which decelerates the load but is not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 100 mm |
| Adjustable range | 80 – 100 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 20 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 SDAJ100X100-20S Is Used
Heavy Press Fitments
Dial the 80-100 mm extend stop to set precise pressing depth for heavy bearings, leveraging the 3927 N push at 0.5 MPa without changing mounting hardware.
Large Fixture Changeover
Adjust the mechanical stop on-site during production line changeovers to accommodate different large product heights quickly within the 20 mm window.
Vertical Lifting Jigs
Lift loads up to 200.2 kg with a 2:1 safety margin, using the M27x2.0 screw to fine-tune the upper travel limit while relying on external checks for holding.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-20S the Right Cylinder?
When sizing this model, compare its 3927 N push at 0.5 MPa against adjacent bores. Stepping down to the SDAJ80 yields 2513.3 N, which may be insufficient for heavy payloads, whereas this 100 mm bore provides a safe working load of roughly 2356 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity near 200.2 kg with a 2:1 margin. Choose the 100 mm bore when you need maximum thrust in a tight footprint.
This cylinder suits operators needing on-site stroke tuning between 80 and 100 mm. Confirm the 20 mm adjustment window, PT3/8 port, and the built-in magnet for switch integration. Remember that a plain cylinder does not hold position upon air loss or valve centering; the fixed bumper only decelerates near the end. 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 80–100 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 SDAJ100X100-20S FAQ
At 0.5 MPa this 100 mm bore cylinder provides 3927 N push and 3524.9 N pull. At 0.7 MPa it yields 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 R screw shortens the extend stroke by up to 20 mm, allowing usable travel from 80 to 100 mm. The included -S magnet enables position detection with AirTAC reed or electronic switches.
