Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-75B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-75B 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 100 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-75B
The AirTAC SDAJ100X100-75B is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the M27x2.0 adjuster screw lets you dial the forward stroke down from the 100 mm maximum to as little as 25 mm directly on the machine, avoiding part swaps. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, yielding 3927 N of push at 0.5 MPa.
This variant uses a male M26x1.5 thread on the 32 mm piston rod and a PT3/8 air port. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit. End-of-travel deceleration relies on a fixed NBR bumper, which is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches without upgrading to the -S option.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 100 mm |
| Adjustable range | 25 – 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 75 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 SDAJ100X100-75B Is Used
Heavy Press Tonnage Setup
Dial the M27x2.0 screw to set the exact 25-100 mm extend position for a heavy press, ensuring precise 3927 N push force without changing mounting hardware.
Assembly Line Changeover
Quickly reposition the mechanical stop during product changeovers on a high-force assembly line, using the 75 mm adjustment window to adapt to new part heights.
Vertical Lift Positioning
Lift loads up to 200.2 kg vertically with a 2:1 margin, tweaking the extend endpoint on the machine to accommodate varying stack heights safely.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-75B the Right Cylinder?
When sizing this bore, compare it both ways: stepping down to the SDAJ80 drops the 0.5 MPa push to 2513.3 N, while this 100 mm bore provides a robust 3927 N. Based on that 0.5 MPa figure, the safe working load is approximately 2356 N (about 60 percent of capacity), and it can manage a vertical lift of roughly 200.2 kg with a 2:1 safety margin. Choose this 100 mm option when you need heavy push force combined with on-site stroke tuning.
Confirm the bore, 100 mm stroke, 75 mm adjust window, PT3/8 port, and male M26x1.5 rod thread match your mounting requirements. A plain actuator does not hold a load if air pressure drops or the valve centers; the piston drifts and the fixed bumper only decelerates near the end of travel. For load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–100 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 SDAJ100X100-75B FAQ
This 100 mm bore cylinder 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 of 801 kgf at 1.0 MPa.
The M27x2.0 screw shortens the extend stop from 100 mm down to 25 mm without altering the force. It is a mechanical stop, not a mid-stroke lock; the cylinder cannot hold a load if air is lost without an external rod lock.
