Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30B 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 25 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30B
The AirTAC SDAJ100X55-30B is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you dial the outward stroke on-site between 25 and 55 mm without changing parts. Because the adjuster sets the mechanical stop rather than the piston area, output force equals a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
This 100 mm bore unit utilizes a short riveted body to minimize axial mounting depth where larger profile cylinders cannot fit. It comes with a male-thread M26x1.5 piston rod and a PT3/8 air port. End shock is managed by a fixed NBR bumper that decelerates the stroke end, but note this is not an adjustable air cushion. This specific SKU lacks a piston magnet, so magnetic sensing is not supported.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 55 mm |
| Adjustable range | 25 – 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 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 SDAJ100X55-30B Is Used
Heavy Press Fitments
Dial the 25-55 mm extend stop to set precise pressing depth for heavy bearings, utilizing the 3927 N push force without swapping mechanical shims.
Tooling Changeovers
Quickly reposition the outward stroke on assembly lines during product family shifts, relying on the M27x2.0 adjuster screw for exact endpoint tuning.
Vertical Lift Stops
Lift loads up to 200.2 kg with a 2:1 margin and fine-tune the lowering endpoint, ensuring the fixed NBR bumper catches the final deceleration safely.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-30B the Right Cylinder?
When sizing this model, evaluate both directions: stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. A practical safe working load is roughly 2356 N, maintaining a 2:1 safety factor, or a vertical lift capacity near 200.2 kg. Choose this unit when your fixture requires precise on-machine stroke tuning during commissioning or tooling changeovers.
Confirm the 100 mm bore, 55 mm maximum stroke, and 30 mm adjust window match your spatial envelope. This variant includes a male M26x1.5 rod thread and no magnet. Remember that a plain cylinder does not hold position upon air loss or valve centering; the fixed bumper only decelerates near the end of travel. For suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–55 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 SDAJ100X55-30B FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. At 0.7 MPa it provides 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The external R (M27x2.0) screw mechanically limits the extend stroke, allowing you to set the outward endpoint anywhere between 25 and 55 mm. It acts as a hard stop and does not alter the cylinder's output force.
