About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-40
The AirTAC SDAJ100X40-40 is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the extend stroke on-site from 0 to 40 mm without changing parts. Because the adjuster only sets the mechanical stop position rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
This 100 mm bore actuator utilizes a short riveted body to minimize axial mounting depth where larger profile or round-body units fail to fit. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Please note this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 40 mm |
| Adjustable range | 0 – 40 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 SDAJ100X40-40 Is Used
Heavy Press Fit Tooling
Dial in the exact 0-40 mm extend stop during initial setup to prevent over-travel when seating heavy bearings, utilizing the full 3927 N push force at 0.5 MPa.
Vertical Lift Stations
Lift loads up to 200.2 kg safely with a 2:1 margin, relying on the short riveted body to save vertical space in tight elevator or shuttle mechanisms.
Multi-Product Assembly Lines
Quickly re-adjust the extend position for different product heights on the same machine without swapping cylinders, ensuring rapid changeover and minimal downtime.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-40 the Right Cylinder?
When sizing this actuator, evaluate your force requirements bidirectionally. Stepping down to the SDAJ80 provides 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore yields 3927 N. A computed safe working load is approximately 2356 N, representing about 60% of the 0.5 MPa push figure, making it suitable for vertical lifts up to roughly 200.2 kg with a 2:1 safety margin.
Choose this model if your fixture requires precise on-site stroke tuning during commissioning or tooling changeovers. Confirm your parameters: 100 mm bore, 40 mm maximum stroke, 40 mm adjust window, PT3/8 port, female M18x1.5 rod thread, and no magnet. Remember that a plain SDAJ does not hold a load if air pressure drops or the valve centers; the fixed bumper only decelerates the stroke end. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–40 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 SDAJ100X40-40 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. It operates between 0.15 and 1.0 MPa, tolerates proof pressures up to 1.5 MPa, and runs at speeds of 30-500 mm/s.
The R (M27x2.0) screw mechanically shortens the extend stroke by up to 40 mm, allowing on-site tuning from 0 to 40 mm; retract remains full stroke. This specific SKU lacks a piston magnet, so it cannot accept AirTAC reed or electronic switches unless you specify the -S magnet option.
