Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30SB 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 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30SB
The AirTAC SDAJ100X85-30SB is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you shorten the forward stroke on-site across a 55 to 85 mm window without swapping parts. The adjuster strictly dictates the mechanical end position, leaving output force identical to a standard 100 mm bore SDA at 3927 N push at 0.5 MPa.
This variant includes a built-in piston magnet for AirTAC reed or electronic switches and a male M26x1.5 threaded rod end. The short riveted body minimizes axial mounting depth where larger profile cylinders cannot fit. End shock is managed solely by a fixed NBR bumper, meaning the stop decelerates the stroke but does not act as a lock or adjustable air cushion.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30SB |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 85 mm |
| Adjustable range | 55 – 85 mm |
| Adjuster thread (R) | M27×2.0 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M18×1.5 F / M26×1.5 male (B) |
| 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 30 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 SDAJ100X85-30SB Is Used
Heavy Press Fitment
Dial in the 55-85 mm extend stop during machine commissioning to set exact pressing depths for large bearings without machining new spacers.
Multi-Product Changeover
Adjust the mechanical stop on-site when switching fabrication lines between thick and thin heavy-gauge assemblies, leveraging the 3927 N push force.
Vertical Lift Stations
Lift loads up to roughly 200.2 kg with a 2:1 safety margin, using the male M26x1.5 rod end for robust tooling attachment in elevation platforms.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30SB the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate both neighbors. Stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this 100 mm unit delivers 3927 N. Since 100 mm is the largest standard SDAJ bore, moving up requires a different frame family. The on-machine 55-85 mm tuning window is ideal for heavy press fit lines needing precise trial positioning. A safe working load is roughly 2356 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of approximately 200.2 kg with a 2:1 margin.
Confirm the 100 mm bore, 85 mm maximum stroke, 30 mm adjust window, and PT3/8 port. This SKU includes the -S magnet and -B male M26x1.5 rod thread. Remember that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 55–85 mm
- ✓ Force at your working pressure
- ✓ Access to reach the R adjuster
- ✓ Magnet (S) for sensors?
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.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30SB FAQ
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 stroke by up to 30 mm, yielding a usable 55-85 mm forward range while retract remains full. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
