About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30
The AirTAC SDAJ100X85-30 is a compact double-acting single-rod cylinder featuring an external M27x2.0 adjustment screw that dials the extend stop directly on your machine. You can set the outward travel anywhere between 55 and 85 mm without swapping shims or components, while the retract distance remains full. Because the adjuster only dictates the mechanical stop position, the output force equals a standard SDA of this bore, delivering about 3927 N push at 0.5 MPa.
Designed to save axial mounting depth where larger profile cylinders cannot fit, this 100 mm bore unit utilizes a short riveted body. It relies on a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Operating at speeds of 30-500 mm/s, it handles heavy positioning tasks efficiently.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30 |
|---|---|
| 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 SDAJ100X85-30 Is Used
Heavy Press Tonnage Setup
Dial in the exact 55 to 85 mm extend stop during press tool commissioning to prevent over-travel, utilizing the 3927 N push force for secure forming operations.
Vertical Lift Dampening
Lift payloads up to roughly 200.2 kg with a 2:1 safety margin, using the fixed NBR bumper to absorb end-of-stroke shock while relying on an external check valve for holding.
Assembly Line Changeover
Quickly reposition the mechanical stop for different product heights on a high-mass assembly line without changing parts, leveraging the short riveted body to save space.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-30 the Right Cylinder?
When sizing this actuator, evaluate both neighboring bores to match your exact payload. Stepping down, the SDAJ80 provides 2513.3 N push at 0.5 MPa, serving as a lighter alternative if your mass allows. Stepping up is not an option as 100 mm is the largest available bore in this family, making this the maximum force choice for compact installations. This specific SKU lacks a piston magnet, so it cannot support reed or electronic switches; select an -S variant if you require position sensing. Confirm your requirements for the 85 mm maximum stroke, the 30 mm adjustment window, the PT3/8 port, and the female M18x1.5 rod-end thread. Remember that a plain cylinder does not hold its load on air loss or when a valve is centered, so integrate an external rod lock or pilot-operated check valve for secure vertical holding.
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 SDAJ100X85-30 FAQ
This 100 mm bore double-acting cylinder generates 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa. It uses a PT3/8 air port and operates at speeds between 30 and 500 mm/s.
The external M27x2.0 screw shortens the extend stroke by up to 30 mm, allowing you to set the outward stop anywhere from 55 to 85 mm on the machine. This SKU does not include a piston magnet, so it cannot accept sensing switches; choose an -S coded model if you need reed or electronic switch integration.
