Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20SB 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 50 to 70 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20SB
The AirTAC SDAJ100X70-20SB is a double-acting, single-rod compact cylinder featuring an external adjustable extend stop. A built-in piston magnet enables position detection with AirTAC reed or electronic switches. Turning the R (M27x2.0) adjuster screw lets you dial the extend stroke down from 70 mm to 50 mm directly on the machine, eliminating the need for shims or part swaps during changeovers.
Because the adjuster sets the mechanical stop 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. The short riveted body conserves axial mounting depth in tight fixtures, while end-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. This specific unit includes a male M26x1.5 piston rod thread and a PT3/8 air port.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20SB |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 70 mm |
| Adjustable range | 50 – 70 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 SDAJ100X70-20SB Is Used
Heavy Press Fitments
Dial in the 50-70 mm extend stop on heavy press operations to prevent over-travel, utilizing the full 3927 N push force at 0.5 MPa without changing hardware.
Multi-Product Assembly Lines
Speed up changeovers by turning the R M27x2.0 screw to set exact extend positions for different product heights, leveraging the compact riveted body for tight cell layouts.
Vertical Lift Stations
Lift loads up to 200.2 kg with a 2:1 safety margin, using the male M26x1.5 rod end to secure heavy tooling while adjusting the stop to avoid hard mechanical crashes.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20SB the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force margins both ways. Dropping down to an SDAJ80 provides 2513.3 N of push at 0.5 MPa, which may be insufficient for heavy loads, whereas this 100 mm bore yields a safe working load of roughly 2356 N (about 60 percent of its 0.5 MPa rating) and can vertically lift approximately 200.2 kg with a 2:1 safety margin. Choose this model if your fixture requires exact on-site stroke tuning between 50 and 70 mm.
Confirm the 100 mm bore, 70 mm maximum stroke, 20 mm adjustment window, PT3/8 port, built-in magnet (S), and male M26x1.5 rod thread (B) match your mounting requirements. Note that a plain compact cylinder does not hold position or load upon air loss or valve centering; the fixed NBR bumper only decelerates near the end of travel. For 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 50–70 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 SDAJ100X70-20SB FAQ
This 100 mm bore double-acting cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and travels at speeds of 30-500 mm/s.
The external R (M27x2.0) screw mechanically shortens the extend stroke by up to 20 mm, allowing on-site tuning between 50 and 70 mm without altering the force. The included -S magnet works with AirTAC reed or electronic switches mounted in the body grooves for end-position sensing.
