Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X100-50SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X100-50SB is a genuine double-acting COMPACT cylinder (Ø80mm bore) whose extend end-position is set by an external M20×1.5 adjustment screw. You can dial the stroke anywhere from 50 to 100 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X100-50SB
The AirTAC SDAJ80X100-50SB is a compact double-acting single-rod cylinder featuring an on-site adjustable extend stop. By turning the external R (M20x1.5) screw, you can dial the forward stroke anywhere between 50 and 100 mm without swapping shims or parts. Because the adjuster only sets the mechanical stop rather than altering the piston area, output force remains identical to a standard 80 mm bore SDA, delivering 2513.3 N of push at 0.5 MPa.
This variant includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches, plus a male M22x1.5 threaded rod end (-B) for secure mechanical attachment. The short riveted body minimizes axial mounting depth in tight machinery, while a fixed NBR bumper decelerates the stroke ends. Note that this bumper is not an adjustable air cushion, and the cylinder relies on live air pressure to maintain position.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 100 mm |
| Adjustable range | 50 – 100 mm |
| Adjuster thread (R) | M20×1.5 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M14×1.5 F / M22×1.5 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 50 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 SDAJ80X100-50SB Is Used
Heavy Press Tonnage Setup
Dial in the 50 to 100 mm extend stop on the fly to set precise forming depth on heavy materials, utilizing the 2513.3 N push force without changing bottoming shims.
Vertical Lift Dwell Positioning
Establish exact upper travel limits for a 128.1 kg vertical lift payload, tweaking the R screw during commissioning to find the perfect dwell height before locking it down.
Multi-Format Changeover Lines
Adapt a clamping station rapidly between product families by rotating the external adjuster, saving axial space with the compact riveted body while handling up to 513 kgf at max pressure.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X100-50SB the Right Cylinder?
When sizing this 80 mm bore actuator, evaluate your force requirements against its neighbours. Dropping down to the SDAJ63 yields 1558.6 N of push at 0.5 MPa, whereas stepping up to the SDAJ100 provides 3927 N. This SDAJ80X100-50SB generates 2513.3 N at 0.5 MPa, offering a safe working load of roughly 1508 N (about 60 percent of capacity) and a vertical lift capability near 128.1 kg with a 2:1 safety margin.
Choose this specific model if your fixture requires frequent changeovers or trial positioning across a 50 mm adjustment band. Confirm your setup needs the PT3/8 air port, the male M22x1.5 rod thread, and the integrated magnet for switch sensing. Remember that a standard compact cylinder cannot hold a load if air pressure drops or the valve centers; the fixed bumper only cushions the end of travel. For suspended or vertical loads that must resist gravity during air loss, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 50–100 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 M20×1.5 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 SDAJ80X100-50SB FAQ
This 80 mm bore double-acting cylinder uses a PT3/8 air port. It generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, 3518.6 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum push of 513 kgf at 1.0 MPa.
The M20x1.5 adjuster screw mechanically limits the extend stroke, allowing you to set the forward end position anywhere between 50 mm and the full 100 mm. The included -S magnet enables position detection using AirTAC reed or electronic switches, while the -B code denotes the male M22x1.5 rod thread.
