Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-20
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-20 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 45 to 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-20
The AirTAC SDAJ100X65-20 is a double-acting compact cylinder featuring an external adjustable extend stop. A front R thread (M27x2.0) screw lets you dial the forward end-position anywhere between 45 and 65 mm directly on the machine, eliminating the need for shims or part swaps. Retract remains full length, and because the adjuster merely sets the mechanical stop rather than altering 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 integrates a 32 mm piston rod and a PT3/8 port within a short riveted body, drastically reducing axial mounting depth where round-body or profile cylinders cannot fit. End-of-travel energy is managed solely by a fixed NBR bumper that decelerates the stroke end; it is not an adjustable air cushion. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-20 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 65 mm |
| Adjustable range | 45 – 65 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 20 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 SDAJ100X65-20 Is Used
Heavy Press Fitment
Dial the 45-65 mm extend stop on the shop floor to seat large bearings precisely, leveraging the 3927 N push at 0.5 MPa without swapping mechanical spacers.
Mold Changeover Systems
Quickly reposition the forward endpoint during injection mold swaps, using the M27x2.0 adjuster screw to accommodate varying tooling depths in tight riveted-body envelopes.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 margin, relying on the fixed NBR bumper to decelerate the downward stroke end while avoiding bulky profile cylinders.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-20 the Right Cylinder?
When sizing this actuator, evaluate both neighbours: stepping down to SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. This specific model suits heavy-duty fixturing requiring precise on-site stroke tuning across its 45-65 mm window. A computed safe working load is approximately 2356 N (about 60% of the 0.5 MPa push figure), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin.
Confirm the 100 mm bore, 65 mm maximum stroke, 20 mm adjust window, PT3/8 port, and female M18x1.5 rod-end thread fit your envelope. Note this SKU lacks a piston magnet, so magnetic sensing is impossible without the -S variant. A plain cylinder does not hold a load on air loss or valve centring; the bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–65 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 SDAJ100X65-20 FAQ
This 100 mm bore double-acting cylinder uses a PT3/8 port and delivers 3927 N push / 3524.9 N pull at 0.5 MPa, 5497.8 N push / 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
The external M27x2.0 screw shortens the extend stroke by up to 20 mm, yielding a usable 45-65 mm range. It acts only as a mechanical stop and does not alter force or lock mid-stroke; the fixed NBR bumper simply decelerates the end. This SKU lacks a magnet, so sensing requires the -S variant for reed or electronic switches.
