Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30SB 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 15 to 45 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30SB
The AirTAC SDAJ80X45-30SB is a compact double-acting single-rod cylinder featuring an external extend stop. Turning the M20x1.5 adjuster screw lets you dial the outward stroke on-site anywhere between 15 and 45 mm without swapping parts. Because the adjuster only sets the mechanical stop position, 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, alongside a male M22x1.5 threaded rod end (-B). The short riveted body minimizes axial footprint where space is tight, while a fixed NBR bumper at each end absorbs end-of-travel shock. Operating speed ranges from 30 to 500 mm/s.

| 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 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 SDAJ80X45-30SB Is Used
Heavy Press Fitment
Dial the 15-45 mm extend stop to precisely seat heavy bearings without reprogramming the machine cycle.
Product Diversion
Adjust the mechanical stop on the fly to handle varying package widths on a high-throughput line.
Vertical Lift Stops
Set safe lifting heights up to 45 mm, relying on the 2513.3 N thrust to elevate components securely.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X45-30SB the Right Cylinder?
When sizing this unit, compare its 2513.3 N push at 0.5 MPa against adjacent bores: the 63 mm version yields 1558.6 N, whereas the 100 mm option jumps to 3927 N. This 80 mm bore is optimal when the smaller frame lacks thrust but the larger frame exceeds your spatial limits. It is specifically engineered for machinery needing frequent on-machine stroke tuning during setup or changeovers. Confirm your requirements for an 80 mm bore, 45 mm maximum stroke, 30 mm window, PT3/8 port, male M22x1.5 rod, and switch readiness. For vertical loads, note that a plain cylinder drifts if air pressure drops; the fixed bumper only decelerates the end of travel and does not lock the piston. Use an external rod lock or pilot-operated check valve for secure load holding without live pressure.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–45 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 SDAJ80X45-30SB FAQ
At 0.5 MPa it provides 2513.3 N push and 2267.8 N pull. At 0.7 MPa it provides 3518.6 N push. The theoretical maximum push is 513 kgf at 1.0 MPa.
The M20x1.5 screw shortens the extend end position from 45 mm down to 15 mm without changing the output force. The built-in magnet allows tracking via AirTAC reed or electronic switches.
