Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20 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 30 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20
The AirTAC SDAJ100X30-20 is a compact double-acting single-rod cylinder featuring an external extend stop. A side-mounted R (M27x2.0) adjuster screw lets you dial the forward stroke down from 30 mm to 10 mm directly on the machine, eliminating the need for shims or part swaps during commissioning. Because the mechanism only limits travel, output force remains identical to a standard 100 mm bore unit, delivering 3927 N of push at 0.5 MPa.
Built with a space-saving riveted body, this model fits where round-body or profile cylinders cannot. It uses a fixed NBR bumper at each end to absorb end-of-stroke shock rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches; you would need the -S variant for position sensing.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 30 mm |
| Adjustable range | 10 – 30 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 SDAJ100X30-20 Is Used
Heavy-Duty Pressing
Dial in the exact 10-30 mm extend stop on-site to apply 3927 N of force without over-travel when seating large bearings or forming thick materials.
Vertical Lift Stops
Lift approximately 200.2 kg with a 2:1 safety margin, using the external R screw to fine-tune the raising height precisely during changeovers.
Riveted Body Assembly
Save axial mounting depth in cramped machinery frames while retaining the full 801 kgf maximum push capacity for heavy clamping duties.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20 the Right Cylinder?
When sizing this 100 mm bore actuator, compare its 3927 N push at 0.5 MPa against neighbouring bores. Stepping down to an SDAJ80 yields 2513.3 N, which may be insufficient for heavy pressing or lifting tasks. Stepping up is impossible as this is the largest standard SDAJ bore, meaning any higher force requirement would require multiple cylinders or an entirely different series. This model suits applications needing exact 10-30 mm extend tuning during setup.
Remember that the adjuster screw acts purely as a mechanical stop, not a mid-stroke lock. A plain SDAJ cylinder will not hold a load if air pressure drops or the valve is centred; the piston drifts. For suspended or vertical loads, install an external rod lock or pilot-operated check valve. Confirm your requirements for the PT3/8 port, female M18x1.5 rod thread, and the lack of a magnet before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–30 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 SDAJ100X30-20 FAQ
This 100 mm bore cylinder features a PT3/8 air port. It delivers 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 push of 801 kgf at 1.0 MPa.
The R (M27x2.0) screw shortens the extend stroke by up to 20 mm, allowing usable travel between 10 and 30 mm. This specific SKU has no piston magnet and cannot take a switch; adding the -S option provides a magnet for reed or electronic sensors.
