Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-50
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-50 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 0 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-50
The SDAJ100X45-50 is a double-acting compact riveted-body cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the outward stroke down from the 45 mm maximum right to zero directly on the machine, eliminating the need for shims or part swaps during setup. Because the adjuster only sets the mechanical stop position, output force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
This 100 mm bore variant uses a PT3/8 air port and a 32 mm piston rod to handle heavy loads within a short axial footprint. End-of-travel shock is managed by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S option.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-50 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 45 mm |
| Adjustable range | 0 – 45 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 SDAJ100X45-50 Is Used
Press Fit Tuning
Dial in the exact 0-45 mm extend stop for heavy press-fit operations, using the full 3927 N push at 0.5 MPa to seat components without over-traveling.
Heavy Fixture Changeover
Quickly re-adjust the outward stroke on production lines during tooling changeovers, leveraging the 100 mm bore's 801 kgf max force for robust actuation.
Vertical Lift Jigs
Lift loads up to 200.2 kg with a 2:1 safety margin, utilizing the M27x2.0 adjuster screw to set precise upward travel limits in vertical lifting jigs.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X45-50 the Right Cylinder?
When sizing this actuator, compare its 3927 N push at 0.5 MPa against adjacent bores: stepping down to the SDAJ80 yields 2513.3 N, while this 100 mm unit provides a theoretical maximum of 801 kgf at 1.0 MPa. Based on the 0.5 MPa figure, a safe working load is roughly 2356 N (about 60 percent capacity), translating to a vertical lift capability of approximately 200.2 kg with a 2:1 safety margin. Choose this model if your fixture requires heavy thrust but demands on-site stroke tuning between 0 and 45 mm.
Confirm the bore, 45 mm stroke, 50 mm adjust window, PT3/8 port, female M18x1.5 rod thread, and the absence of a magnet for this configuration. Remember 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 of travel. For load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–45 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 SDAJ100X45-50 FAQ
This 100 mm bore double-acting 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, with a theoretical maximum push of 801 kgf at 1.0 MPa.
The external R (M27x2.0) screw mechanically shortens the extend stop by up to 50 mm, allowing you to set the outward travel anywhere from 0 to 45 mm. It sets the stop position only and does not alter the output force or lock the piston mid-stroke.
