Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30SB 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 25 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30SB
The AirTAC SDAJ80X55-30SB is a compact double-acting single-rod cylinder engineered for on-site extend-stop tuning. By turning the external M20x1.5 adjuster screw, you set the forward stroke anywhere between 25 and 55 mm without swapping shims or parts. Because the mechanism limits travel rather than altering piston area, output remains identical to a standard 80 mm bore SDA, delivering 2513.3 N of push force at 0.5 MPa.
This variant includes a built-in piston magnet for AirTAC reed or electronic switches and features a male M22x1.5 threaded rod end. Its short riveted body minimizes axial mounting depth where space is tight. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

| Cushion | Fixed NBR bumper (both ends) |
The adjustment screw shortens the extend stroke by up to 30 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 SDAJ80X55-30SB Is Used
Press Fit Dial-In
Ideal for assembly stations needing precise part seating; the 30 mm adjustment window lets operators fine-tune the 2513.3 N extend force to exact component depths without reprogramming logic.
Multi-Product Changeover
Useful on lines running varied batch sizes where the male M22x1.5 rod interfaces with changeable tooling, allowing rapid 25 to 55 mm stroke modifications for different fixture heights.
Vertical Lift Stops
Deployed in elevators handling up to 128.1 kg with a 2:1 margin, granting technicians the flexibility to set exact upper travel limits mechanically via the M20x1.5 screw.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30SB the Right Cylinder?
When sizing this 80 mm bore actuator, compare it directly against its neighbors. Dropping down to an SDAJ63 yields 1558.6 N of push at 0.5 MPa, whereas stepping up to an SDAJ100 provides 3927 N. This SDAJ80X55-30SB generates 2513.3 N at 0.5 MPa, translating to a safe working load of roughly 1508 N or a vertical lift capacity of about 128.1 kg with a 2:1 safety margin.
Choose this specific configuration when you require exact forward-position dialing during frequent machine changeovers. Confirm your setup requires the 25-55 mm adjustable window, a PT3/8 air port, and the male M22x1.5 piston rod. Note that a plain cylinder drifts when air is lost or a valve centers; the fixed 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 25–55 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 SDAJ80X55-30SB 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, with a theoretical maximum of 513 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa at speeds of 30-500 mm/s.
The external M20x1.5 screw mechanically shortens the extend stop from the 55 mm maximum down to 25 mm without changing the force output. The included -S magnet enables position detection using AirTAC reed or electronic solid-state switches mounted in the body grooves.
