About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X20-20SB
The SDAJ100X20-20SB is a robust double-acting compact cylinder featuring an external R (M27x2.0) adjuster screw that lets you dial the extend stop down from 20 mm to 0 mm directly on the machine. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa. Its short riveted body saves valuable axial mounting depth where larger profile or round-body units cannot fit, while the integrated magnet supports position feedback.
This specific configuration includes the -S magnet for AirTAC reed or electronic switches and the -B male-thread piston rod (M26x1.5) for secure external mounting. End-of-stroke impact is managed by a fixed NBR bumper that decelerates the load, though it is not an adjustable air cushion. Operating pressure spans 0.15 to 1.0 MPa, and the PT3/8 air port handles the high volume required for this 100 mm bore.

| 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 SDAJ100X20-20SB Is Used
Press Fit Tooling
Dial the 0-20 mm extend stop to precisely seat heavy bearings, using the 3927 N push force to overcome assembly friction without over-traveling.
Heavy Clamp Changeover
Quickly reset the male-thread rod position between product families on a machining line, relying on the fixed NBR bumper to absorb the 200.2 kg clamping mass.
Vertical Lift Positioning
Adjust the extend endpoint on-site for varying lift heights, ensuring the mechanical stop catches the load safely before the bottom of the stroke.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X20-20SB the Right Cylinder?
When sizing this actuator, evaluate your force requirements bidirectionally: the SDAJ80 provides 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore generates 3927 N. A computed safe working load is roughly 2356 N, representing about 60% of the 0.5 MPa push figure, which translates to a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin. Choose the 100 mm option when the smaller bore cannot overcome your friction and mass, but avoid oversizing if 80 mm already suffices.
This model is built for heavy setups requiring frequent on-site stroke tuning without part changes. Confirm your parameters: 100 mm bore, 20 mm stroke, 20 mm adjust window, PT3/8 port, male M26x1.5 rod, and a built-in magnet. Note that a plain cylinder does not hold its load if air pressure drops or the valve centers—the piston will drift. For load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist

- ✓ 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 SDAJ100X20-20SB FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push and 3524.9 N of pull. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw lets you shorten the extend stroke by up to 20 mm, allowing any stop position between 0 and 20 mm without changing parts. The included -S magnet works with AirTAC reed or electronic switches for end-of-stroke sensing.
