The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X150-75S 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 75 to 150 mm on the machine — no shims, no part change.
The AirTAC SDAJ100X150-75S is a 100mm bore double-acting compact cylinder featuring an external R (M27x2.0) adjuster screw that dials the extend stop from 75 to 150mm without changing parts. Because the mechanism limits travel rather than altering piston area, output force equals a standard SDA of this bore, delivering 3927N push at 0.5MPa. The short riveted body saves axial mounting depth where larger profile or round-body actuators cannot fit.
This specific 150mm stroke configuration exceeds the 130mm standard maximum for this bore size, making it a non-standard, made-to-order item. It includes a built-in piston magnet (-S) for AirTAC reed or electronic switches, and relies on a fixed NBR bumper at each end to decelerate the stroke rather than an adjustable air cushion.

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.
| 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.

Dial in the exact 75 to 150mm extend stop on heavy press fittings without swapping shims, using the full 3927N push force at 0.5MPa to seat components precisely.
Adapt large actuators quickly during product changeovers by turning the M27x2.0 adjuster screw, saving axial depth in tight machine frames with its compact riveted body.
Safely lift loads up to 200.2kg with a 2:1 margin while fine-tuning the descent end-stop, relying on the fixed NBR bumper to absorb the impact energy.
When sizing this actuator, compare both ways: stepping down to an SDAJ80 yields 2513.3N push at 0.5MPa, whereas this 100mm bore provides 3927N. Based on that 0.5MPa figure, a safe working load is roughly 2356N (about 60% of capacity), allowing a vertical lift of approximately 200.2kg with a 2:1 safety margin. Choose this model when your fixture requires on-site stroke tuning across a 75mm window during frequent changeovers.
Confirm the 100mm bore, 150mm stroke, 75mm adjustability window, and PT3/8 port. The -S code indicates the magnet is present for sensing, and the rod end has a female M18x1.5 thread. Remember that a plain compact cylinder does not hold its load on air loss or valve centring; the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, specify an external rod lock or pilot-operated check valve.
Quick checklist
This 100mm bore double-acting cylinder provides 3927N push and 3524.9N pull at 0.5MPa, 5497.8N push and 4934.8N pull at 0.7MPa, and a theoretical maximum of 801kgf at 1.0MPa.
The external R (M27x2.0) screw shortens the extend stroke on-site from the 150mm maximum down to 75mm without changing parts. The -S suffix means a built-in magnet is included for direct mounting of AirTAC reed or electronic solid-state switches.
