The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-20SB 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 55 to 75 mm on the machine — no shims, no part change.
The AirTAC SDAJ100X75-20SB is a double-acting compact cylinder featuring an external adjustable extend stop. A built-in piston magnet enables position sensing with AirTAC reed or electronic switches. The M27x2.0 adjuster screw lets you dial the extend end-position anywhere between 55 and 75 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. This unit includes a male M26x1.5 piston rod thread.
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 about 3927 N push at 0.5 MPa. The short riveted body saves valuable axial mounting depth where a larger profile cylinder will not fit. End shock is managed solely by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion.

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.
| 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 55 to 75 mm extend stop on heavy press fitments to prevent over-travel, utilizing the 3927 N push force at 0.5 MPa for consistent seating.
Speed up large mold changeover by turning the M27x2.0 adjuster screw to accommodate varying mold heights without machining new spacers.
Lift vertical payloads up to 200.2 kg with a 2:1 safety margin, relying on the fixed NBR bumper to decelerate the heavy load at the stroke end.
When sizing this 100 mm bore actuator, consider the SDAJ80 as the next bore down, which provides 2513.3 N push at 0.5 MPa. If your application requires less force, stepping down saves space, but this SDAJ100 provides a safe working load of roughly 2356 N, calculated as about 60 percent of its 3927 N capacity at 0.5 MPa. For vertical lifting, this translates to a 200.2 kg payload when applying a 2:1 safety margin. Choose this specific model if your heavy fixture setup requires frequent on-site stroke tuning within the 55 to 75 mm window.
Confirm the 100 mm bore, 75 mm maximum stroke, 20 mm adjust window, and PT3/8 air port match your pneumatic supply. This configuration includes the -S magnet for switch sensing and the -B male M26x1.5 rod thread. Remember that a plain cylinder does not hold a load if air pressure drops or the valve centers; the piston will drift. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve into your circuit.
Quick checklist
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push at 0.7 MPa. The theoretical maximum push force is 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw shortens the extend stroke by up to 20 mm, yielding a usable extend range of 55 to 75 mm. The included -S magnet works with AirTAC reed or electronic switches for end-position sensing, while the fixed NBR bumper decelerates the stroke end.
