Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50SB 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 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50SB
The AirTAC SDAJ100X75-50SB is a compact double-acting single-rod cylinder engineered for heavy-duty positioning where the extend endpoint must be dialed in on the machine. A front R (M27x2.0) adjustment screw lets you shorten the forward stroke by up to 50 mm, yielding a usable extend range of 25 to 75 mm without swapping shims or parts. Retract remains full length. Because the adjuster merely sets the mechanical stop rather than altering the piston area, output force equals a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
This model carries the -S option for a built-in piston magnet, enabling position sensing via AirTAC reed or electronic solid-state switches fitted into the body grooves. The -B code denotes a male-threaded M26x1.5 piston rod end (default is female M18x1.5) for direct tool or fixture mounting. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit. End shock is managed by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion.

| 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 50 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 SDAJ100X75-50SB Is Used
Heavy Press Fit Tooling
Dial in the 25 to 75 mm extend stop on the factory floor to seat large bearings precisely, leveraging the 3927 N push at 0.5 MPa without over-traveling the male M26x1.5 rod.
High-Capacity Diverter Arms
Tune the actuation reach on the fly during product changeovers. The compact riveted body saves axial space along the conveyor frame while delivering up to 801 kgf of theoretical force.
Vertical Lift Stops
Set exact lifting heights for heavy pallets. With a safe working load near 2356 N, the external R screw lets operators adjust the extend endpoint without part changes, though a separate check valve is needed for load holding.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-50SB the Right Cylinder?
Choosing this 100 mm bore provides a theoretical maximum push of 801 kgf at 1.0 MPa, with 5497.8 N of thrust at 0.7 MPa. Sizing both ways, stepping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore delivers 3927 N at that same pressure. The computed safe working load is roughly 2356 N, equating to about 60 percent of the 0.5 MPa figure, which allows a vertical lift of approximately 200.2 kg with a 2:1 safety margin. Select this unit when your setup requires heavy thrust plus on-site stroke tuning between 25 and 75 mm. Confirm your requirements for the PT3/8 air port, the male M26x1.5 rod thread, and the integrated magnet.
Remember that a standard compact cylinder does not hold a load if air pressure drops or the directional valve centers; the piston will drift. The fixed NBR bumper and the R screw only manage end-of-stroke deceleration and positioning, functioning as a mechanical stop rather than a lock. For suspended or gravity-loaded applications requiring fail-safe holding without live pressure, you must add an external rod lock or a pilot-operated check valve.

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.
