Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50B 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 70 to 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50B
The AirTAC SDAJ100X120-50B is a double-acting compact cylinder featuring an external R (M27x2.0) adjuster screw that dials the extend stop precisely between 70 and 120 mm. By turning this screw, you can shorten the forward stroke on-site without shims or part changes, making it highly effective for final positioning tweaks during machine commissioning.
Despite the adjustable end-position, output force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa because the mechanism sets a mechanical stop rather than altering the piston area. The short riveted body saves axial mounting depth where a larger profile cylinder would not fit. End shock is handled by a fixed NBR bumper which decelerates the stroke end but is not an adjustable air cushion. This specific SKU includes a male M26x1.5 piston rod thread and lacks a piston magnet, meaning it cannot accept reed or electronic switches.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 120 mm |
| Adjustable range | 70 – 120 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 50 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 SDAJ100X120-50B Is Used
Heavy Press Fit Tuning
Dial in the exact 70 to 120 mm extend stop during press assembly commissioning to prevent over-travel on sensitive bearings, utilizing the full 3927 N push at 0.5 MPa.
Large Fixture Changeover
Quickly adapt the male M26x1.5 rod extension point for different product families on a machining line without disassembling the compact riveted body.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 safety margin, relying on the fixed NBR bumper to decelerate the stroke end while setting the exact lower stop via the R screw.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-50B the Right Cylinder?
When sizing this unit, 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. Based on the 0.5 MPa figure, a safe working load is roughly 2356 N (about 60 percent of capacity), or a vertical lift of approximately 200.2 kg with a 2:1 safety margin. Choose this model when your fixture requires on-site stroke tuning within the 70 to 120 mm window.
Confirm the 100 mm bore, 120 mm maximum stroke, 50 mm adjustability window, and PT3/8 port. The male M26x1.5 rod end (-B) must match your mating fixture, and you should avoid side loading the 32 mm rod. Note that a plain SDAJ does not hold position or load when air is lost or the valve is centred; the fixed bumper only decelerates near the end and the adjuster is a mechanical stop, not a lock. For load holding without live pressure, utilize an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 70–120 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 SDAJ100X120-50B FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, or 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa. Operating pressure is 0.15 to 1.0 MPa, with an operating speed of 30 to 500 mm/s.
The M27x2.0 adjuster screw mechanically shortens the extend stroke by up to 50 mm, allowing you to set the end position anywhere between 70 and 120 mm without shims; retract remains full. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches. You would need the -S variant for sensing capabilities.
