About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-30B
The AirTAC SDAJ100X70-30B is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the forward end-position anywhere between 40 and 70 mm directly on your 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.
This 100 mm bore unit relies on a fixed NBR bumper at each end to absorb shock rather than an adjustable air cushion. Its short riveted body saves valuable axial mounting depth in tight machinery, and the male M26x1.5 piston rod (designated by the B option) provides a robust threaded interface for your tooling.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-30B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 70 mm |
| Adjustable range | 40 – 70 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 SDAJ100X70-30B Is Used
Heavy Press Fitments
Dial in the 40-70 mm extend stop to set precise insertion depths for heavy bearing presses, leveraging the 3927 N push force without changing tooling.
Multi-Product Assembly Lines
Quickly reconfigure the mechanical stop during product changeovers to accommodate different component heights, saving valuable commissioning time.
Vertical Lift Stations
Handle loads up to 200.2 kg with a 2:1 safety margin, using the adjustable forward stop to prevent over-travel during upward positioning tasks.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-30B the Right Cylinder?
When sizing this actuator, compare its 3927 N push at 0.5 MPa against neighboring bores. Stepping down to the SDAJ80 yields 2513.3 N, whereas moving up is not an option as 100 mm is the largest available bore. This makes the SDAJ100 the definitive choice when your application demands maximum thrust within this compact frame. A computed safe working load is roughly 2356 N, equating to about 60% of the 0.5 MPa push figure, which allows a vertical lift of approximately 200.2 kg with a 2:1 safety margin.
Opt for this specific model if your fixture requires precise on-site stroke tuning between 40 and 70 mm during commissioning or tooling changeovers. Confirm the PT3/8 port, the 30 mm adjustment window, and the male M26x1.5 rod thread suit your mounting plate. Note that a plain SDAJ cannot hold a load if air pressure drops or the valve is centered; the fixed bumper only decelerates the stroke end. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 40–70 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 SDAJ100X70-30B FAQ
This 100 mm bore cylinder provides 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, and a theoretical maximum of 801 kgf at 1.0 MPa. The adjustment screw does not alter these force values.
The R (M27x2.0) screw shortens the extend stroke by up to 30 mm, allowing you to set the forward stop anywhere between 40 and 70 mm. The B option specifies a male M26x1.5 threaded piston rod. This SKU lacks a piston magnet, so it cannot use reed or electronic switches; you would need the -S variant for sensing.
