The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X25-10 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 15 to 25 mm on the machine — no shims, no part change.
The AirTAC SDAJ100X25-10 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 anywhere between 15 and 25 mm directly on the machine, avoiding shims or part swaps. Because the mechanism only sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, yielding 3927 N of push at 0.5 MPa.
Built with a short riveted body, this unit saves substantial axial mounting depth where larger profile or round-body cylinders cannot fit. End-of-travel energy is managed solely by a fixed NBR bumper, which decelerates the piston near the end of the stroke but is not an adjustable air cushion. Operating pressure spans 0.15 to 1.0 MPa, and the piston speed ranges from 30 to 500 mm/s.

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 15 to 25 mm contact depth on high-tonnage pressing stations without disassembling the tooling, leveraging the 3927 N push at 0.5 MPa.
Secure large automotive castings in confined cells where axial length is restricted, using the compact riveted body and M27x2.0 adjuster to fine-tune clamp position.
Lift payloads up to 200.2 kg with a 2:1 margin and set the precise raise height, while relying on an external check valve to hold the load safely when air drops.
When sizing this 100 mm bore actuator, evaluate your force requirements bidirectionally. Stepping down to an SDAJ80 reduces the 0.5 MPa push figure to 2513.3 N, which may be insufficient for heavy moving masses, whereas this 100 mm option provides a robust 3927 N. Based on the 0.5 MPa rating, a safe working load is approximately 2356 N (about 60 percent of capacity), translating to a vertical lift capability of roughly 200.2 kg with a 2:1 safety margin. Choose this specific model if your assembly line requires frequent on-site stroke tuning within the 15 to 25 mm window.
Confirm the 100 mm bore, 25 mm maximum stroke, and 10 mm adjustability window suit your cycle timing. This base SKU lacks a piston magnet (-S), so it cannot accept AirTAC reed or electronic switches for position sensing. The rod end features a female M18x1.5 thread (or male M26x1.5 on the B variant) on a 32 mm rod, and the air port is PT3/8. Remember that a standard cylinder does not hold position upon air loss or valve centering; the fixed bumper only decelerates near the end of travel and is not a lock. For suspended or vertical loads, specify an external rod lock or a pilot-operated check valve.
Quick checklist
This 100 mm bore cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The external M27x2.0 screw acts as a mechanical stop that shortens the extend stroke by up to 10 mm, allowing you to set the forward position anywhere between 15 and 25 mm. It does not alter the output force, and the retract stroke remains full length.
