Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30B 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 35 to 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30B
The AirTAC SDAJ100X65-30B is a double-acting compact cylinder featuring an external extend stop. A M27x2.0 adjuster screw lets you dial the outward stroke anywhere between 35 and 65 mm directly on your equipment. Because the mechanism sets the physical stop rather than altering the piston area, you retain the full thrust of a standard 100 mm bore SDA, delivering 3927 N of push force at 0.5 MPa.
This variant uses a male M26x1.5 piston rod thread and a PT3/8 air port. The short riveted body saves valuable axial mounting depth where a larger profile cylinder cannot fit. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

| 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 SDAJ100X65-30B Is Used
Heavy Press Tuning
Dial in the exact 35 to 65 mm contact depth for a 200.2 kg vertical pressing task without machining new spacers.
Multi-Product Forming
Adjust the outward mechanical stop on-site to accommodate different workpiece heights during production line changeovers.
Bending Setup
Fine-tune the 3927 N extend position during trial bends to achieve the correct angle before running a full batch.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X65-30B the Right Cylinder?
Choosing this 100 mm bore provides massive thrust, pushing 3927 N at 0.5 MPa. If you size down, the adjacent SDAJ80 delivers 2513.3 N at 0.5 MPa, which might be insufficient for heavy pressing. Since this is the largest standard compact bore, sizing up requires a different frame style entirely. A practical safe working load is roughly 2356 N, or a 200.2 kg vertical lift with a 2:1 safety margin.
Operators needing frequent changeovers or trial positioning will benefit from the 30 mm adjustment window. Confirm your requirements for the 65 mm maximum stroke, PT3/8 port, and male M26x1.5 rod. Note that this SKU lacks a magnet, so it cannot support reed or electronic switches. Furthermore, the mechanical stop and bumper do not hold the load if air pressure drops; install an external rod lock or pilot-operated check valve for secure load holding.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–65 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 SDAJ100X65-30B FAQ
At 0.5 MPa it provides 3927 N of push and 3524.9 N of pull. At 0.7 MPa the push is 5497.8 N and pull is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 screw mechanically limits the extend stroke, allowing you to set the end position anywhere between 35 and 65 mm. It does not alter the thrust output and is not a mid-stroke lock.
