About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-40
The AirTAC SDAJ100X50-40 is a double-acting compact cylinder featuring an external R (M27x2.0) adjuster screw that dials the extend stop from 10 to 50 mm directly on your machinery. Because the mechanism limits travel rather than altering piston area, output remains identical to a standard SDA of this bore, delivering 3927 N of push force at 0.5 MPa. The short riveted body minimizes axial footprint, fitting heavy-duty applications where longer profile or round-body units cannot.
End-of-travel energy is managed solely by a fixed NBR bumper that decelerates the mass near the stop; it is not an adjustable air cushion. Operating speed spans 30-500 mm/s, and the PT3/8 port feeds the 32 mm piston rod. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 50 mm |
| Adjustable range | 10 – 50 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 SDAJ100X50-40 Is Used
Heavy Press Tonnage Setup
Dialing the extend stop between 10 and 50 mm allows operators to set precise forming depth on heavy presses without swapping mechanical shims during product changeovers.
Vertical Lift Dampening
Lifting a 200.2 kg load with a 2:1 safety margin is well within capacity, while the fixed NBR bumper absorbs the end-of-stroke shock when raising heavy platens.
Compact Riveted Body Clamping
Delivering 3927 N of clamping force at 0.5 MPa, the space-saving riveted body fits into tight automated welding cells where axial length is restricted.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X50-40 the Right Cylinder?
When sizing this unit, evaluate your force requirements bidirectionally: the 80 mm bore yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm option provides 3927 N. If your setup carries a safe working load around 2356 N (60 percent of the 0.5 MPa rating) or needs a 2:1 vertical lift margin up to 200.2 kg, this larger bore is the correct choice. Confirm the 50 mm maximum stroke, the 40 mm adjustment window, PT3/8 porting, and the female M18x1.5 rod thread.
Operators who require frequent changeovers or trial positioning will benefit from the on-site stop tuning. Remember that the fixed NBR bumper and mechanical adjuster do not serve as a brake; if you must hold a load vertically during air loss or valve centering, install an external rod lock or pilot-operated check valve. This configuration ships without a magnet, so sensing is unsupported unless specified otherwise.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–50 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 SDAJ100X50-40 FAQ
At 0.5 MPa this 100 mm bore cylinder provides 3927 N of push force and 3524.9 N of pull force. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
Turning the M27x2.0 adjuster screw shortens the extend end-position by up to 40 mm, yielding a usable extend range of 10 to 50 mm. The retract stroke remains full, and the screw acts purely as a mechanical stop without altering the output force.
