The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X15-10 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 5 to 15 mm on the machine — no shims, no part change.
The AirTAC SDAJ100X15-10 is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the forward end-position between 5 and 15 mm directly on the machine, eliminating shims or part changes during commissioning. Because the adjuster sets the mechanical stop rather than the piston area, output force remains identical to a standard SDA of this bore, providing 3927 N push at 0.5 MPa.
This 100 mm bore unit relies on a fixed NBR bumper to decelerate the stroke end rather than an adjustable air cushion. Its short riveted body saves axial mounting depth where a larger profile cylinder will not fit. Operating speed spans 30-500 mm/s, and the PT3/8 port matches the bore's air requirements.

The adjustment screw shortens the extend stroke by up to 10 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 the 5-15 mm extend stop on heavy press fitments to perfect the insertion depth of large bearings without swapping mechanical shims.
Apply 3927 N of clamping force in compact automated cells where axial mounting depth is restricted by the short riveted body.
Adjust the forward position on the fly during production line changeovers to accommodate varying large-component heights.
When sizing this actuator, evaluate both neighbours: stepping down to SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches; select the -S variant if sensing is required. Confirm the 15 mm stroke, 10 mm adjust window, PT3/8 port, and female M18x1.5 rod-end thread for your mounting interface.
The mechanical stop is not a mid-stroke lock. A plain cylinder does not hold its load on air loss or valve centring—the piston drifts and the fixed bumper only decelerates near the end. For secure vertical load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
This 100 mm bore double-acting 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 R (M27x2.0) screw shortens the extend stop by up to 10 mm, giving a usable 5-15 mm range. A fixed NBR bumper decelerates the stroke end; it is not an adjustable air cushion, and the screw acts as a mechanical stop rather than a mid-stroke lock.
