Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-40B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-40B 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 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-40B
The AirTAC SDAJ100X75-40B is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the outward stroke anywhere between 35 and 75 mm directly on your machine, avoiding shims or part swaps. Because the adjuster only sets the mechanical stop and not the piston area, output force equals a standard SDA of this bore, delivering about 3927 N push at 0.5 MPa.
This unit features a male-thread piston rod (M26x1.5) and a PT3/8 air port. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit. End shock is handled by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion. Note this SKU lacks a piston magnet, so it cannot host reed or electronic switches.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 75 mm |
| Adjustable range | 35 – 75 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 SDAJ100X75-40B Is Used
Heavy Press Tuning
Dial the 35-75 mm extend stop on the shop floor to set precise pressing depth for 200.2 kg vertical lifts without changing shims.
Multi-Product Changeover
Quickly reposition the outward stroke within the 40 mm window when switching between heavy fixtures on a shared line.
Compact Clamping Stations
Leverage the short riveted body to fit high-force 3927 N clamping into tight axial spaces where larger cylinders fail.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X75-40B the Right Cylinder?
When sizing this 100 mm bore, look at the adjacent SDAJ80, which provides 2513.3 N push at 0.5 MPa. Step up to this 100 mm unit when you need the full 3927 N push, but remember the theoretical maximum is 801 kgf at 1.0 MPa. A computed safe working load is roughly 2356 N (about 60 percent of the 0.5 MPa figure), allowing a vertical lift of about 200.2 kg with a 2:1 margin.
Operators who require frequent on-site stroke tuning for changeovers will benefit from the 40 mm adjustment window. Confirm your requirements for the 100 mm bore, 75 mm maximum stroke, 40 mm window, PT3/8 port, male M26x1.5 rod thread, and no magnet. A plain cylinder does not hold its load when air is lost or the valve is centred; the piston drifts and the bumper only decelerates near the end. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–75 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 SDAJ100X75-40B FAQ
At 0.5 MPa it provides 3927 N push and 3524.9 N pull. At 0.7 MPa it provides 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The R (M27x2.0) screw shortens the extend stop by up to 40 mm, giving a usable 35-75 mm outward range while retract remains full. This SKU includes a male M26x1.5 rod thread and lacks a piston magnet, so it cannot take magnetic switches.
