Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-20SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-20SB 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 35 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-20SB
The AirTAC SDAJ80X55-20SB is a compact double-acting single-rod cylinder engineered for on-site extend positioning. By turning the external M20x1.5 adjuster screw, you shorten the forward stroke anywhere between 35 and 55 mm without swapping shims or components. Because the mechanism solely dictates the mechanical stop rather than altering the piston area, output remains identical to a standard SDA of this bore, delivering 2513.3 N of push force at 0.5 MPa.
Housed within a short riveted body, this unit conserves axial mounting depth where round-body or profile alternatives cannot fit. It features a male M22x1.5 piston rod thread and a PT3/8 air port. End-of-travel deceleration relies on a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. The integrated piston magnet supports AirTAC reed or electronic solid-state switches for precise position confirmation.

| 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 (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 SDAJ80X55-20SB Is Used
Press Fit Dial-In
Achieve exact insertion depths on bearing presses by tweaking the 35-55 mm extend stop on the machine, utilizing the 2513.3 N push force without changing hardware.
Vertical Lift Stops
Raise components up to 128.1 kg with a 2:1 margin, adjusting the male M22x1.5 rod endpoint precisely to clear obstructions on varying product heights.
Changeover Positioning
Speed up production line format changes by turning the M20x1.5 adjuster to set new extend endpoints instantly, avoiding the downtime of mechanical shim swaps.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-20SB the Right Cylinder?
When sizing this 80 mm bore actuator, evaluate your force requirements bidirectionally. Stepping down to the SDAJ63 yields 1558.6 N of push at 0.5 MPa, whereas upgrading to the SDAJ100 provides 3927 N. This model sits comfortably in the middle, offering a safe working load of roughly 1508 N—about 60 percent of its 2513.3 N capacity at 0.5 MPa—and a vertical lift capability near 128.1 kg with a 2:1 safety margin.
Choose this specific configuration if your fixture requires exact forward endpoint tuning during frequent changeovers. Confirm your setup requires the 35-55 mm adjustability window, a PT3/8 supply connection, and the male M22x1.5 rod end. Remember that a standard compact cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates the stroke end and does not function as a lock. For suspended loads, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–55 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 SDAJ80X55-20SB FAQ
This 80 mm bore double-acting cylinder provides 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, and a theoretical maximum of 513 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
The M20x1.5 screw limits the extend stroke between 35 and 55 mm without altering the force output. The included -S magnet pairs with AirTAC reed or electronic switches mounted in the body grooves for end-position sensing.
