The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X20-10SH 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 10 to 20 mm on the machine — no shims, no part change.
The AirTAC SDAJ100X20-10SH is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the extend stroke down from its 20 mm maximum to 10 mm directly on the machine, eliminating the need for shims or part swaps during setup. The adjuster sets the mechanical stop position without altering the piston area, delivering a push force of 3927 N at 0.5 MPa identical to a standard SDA of this bore.
This 100 mm bore unit saves axial mounting depth where a larger profile cylinder will not fit, utilizing a short riveted body. It includes a built-in piston magnet for AirTAC reed or electronic switches and uses a fluororubber (FKM) seal for heightened temperature and oil resistance. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

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 in the exact 10-20 mm extend stop for pressing heavy bearings, using the 3927 N push at 0.5 MPa to seat components without over-traveling during initial changeover.
Lift loads up to 200.2 kg with a 2:1 margin, relying on the fixed NBR bumper to decelerate the load at the end of the stroke while the FKM seal handles heated environments.
Fit the short riveted body into tight machine frames to execute forming operations, fine-tuning the extend endpoint on-site via the M27x2.0 adjuster screw to perfect the crimp depth.
When sizing this model, compare its 3927 N push at 0.5 MPa against the neighboring SDAJ80, which yields 2513.3 N at the same pressure. If your application requires less force, the 80 mm bore is more compact; if you need maximum thrust, this 100 mm bore is the largest standard SDAJ option. The computed safe working load is approximately 2356 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin.
This configuration is ideal for heavy setup-heavy lines requiring precise trial positioning. Confirm the bore (100 mm), stroke (20 mm), window (10 mm), and PT3/8 port. Note that a plain SDAJ does not hold position or load when air is lost or the valve is centered; the fixed bumper only decelerates near the end. For load holding without live pressure, utilize an external rod lock or pilot-operated check valve.
Quick checklist
This 100 mm bore cylinder delivers a push of 3927 N and a pull of 3524.9 N at 0.5 MPa. At 0.7 MPa, push is 5497.8 N and pull is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The R (M27x2.0) screw shortens the extend stop by up to 10 mm, giving a usable extend range of 10-20 mm; retract remains full. The -S code indicates a built-in piston magnet for AirTAC reed or electronic switches, and the -H code specifies a fluororubber (FKM) seal.
