Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-40B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-40B 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 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-40B
The AirTAC SDAJ100X55-40B is a double-acting compact cylinder featuring a male-thread M26x1.5 piston rod and an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the forward end-position anywhere between 15 and 55 mm directly on the machine, eliminating the need for shims or part swaps. Because the adjuster only sets the mechanical stop and not the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
Built with a short riveted body, this unit saves axial mounting depth where a larger profile cylinder will not fit. It handles operating pressures from 0.15 to 1.0 MPa and speeds of 30-500 mm/s. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning the stop screw is a positioning tool and never a mid-stroke lock.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 55 mm |
| Adjustable range | 15 – 55 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 40 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 SDAJ100X55-40B Is Used
Heavy Press Fitment
Dial the 15-55 mm extend stop during initial tooling setup to precisely seat large bearings without over-traveling the 3927 N push force.
Multi-Product Forming Line
Quickly turn the R screw during changeover to accommodate different blank heights, leveraging the full 801 kgf max thrust for deep drawing operations.
Vertical Lift Stations
Lift loads up to 200.2 kg safely with a 2:1 margin, adjusting the downward stop exactly to the transfer height while relying on external checks for holding.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-40B the Right Cylinder?
When sizing this 100 mm bore actuator, consider the neighboring SDAJ80, which provides 2513.3 N of push at 0.5 MPa. If your application requires less force, stepping down saves mounting space, but if you need maximum thrust, this model yields a safe working load of roughly 2356 N, or about 60% of its 3927 N rating at 0.5 MPa. This translates to a vertical lift capacity of approximately 200.2 kg when applying a 2:1 safety margin.
Choose this specific SKU if your fixture requires on-site stroke tuning during commissioning or frequent changeovers. Confirm your setup needs the male M26x1.5 rod thread, the PT3/8 air port, and the 40 mm adjustment window. Note that a plain cylinder does not hold a load if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–55 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 SDAJ100X55-40B FAQ
This 100 mm bore cylinder uses a PT3/8 air port. It generates 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 push of 801 kgf at 1.0 MPa.
The external M27x2.0 screw mechanically shortens the forward stroke by up to 40 mm, allowing you to set the extend position anywhere from 15 mm to the full 55 mm. This specific SKU lacks a piston magnet, so it cannot take a magnetic switch; you would need the -S variant to use reed or electronic sensors.
