Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30B 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 SDAJ80X55-30B
The AirTAC SDAJ80X55-30B is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the M20x1.5 adjuster screw, you can dial the extend position anywhere between 25 and 55 mm directly on your machine, avoiding part swaps. Because the adjuster sets the mechanical stop rather than the piston area, output force remains identical to a standard SDA of this bore, delivering 2513.3 N of push at 0.5 MPa.
This variant features a male-thread M22x1.5 piston rod for secure heavy-load attachment. The short riveted body significantly reduces axial mounting depth compared to round-body alternatives, fitting into tighter machinery footprints. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 55 mm |
| Adjustable range | 25 – 55 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 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 SDAJ80X55-30B Is Used
Press Fit Tuning
Dial in the exact 25-55 mm extend depth for pressing bearings without swapping shims, leveraging the 2513.3 N push force to seat heavy components.
Variable Flap Folding
Adjust the mechanical stop on the fly to accommodate different carton depths on a packaging line, using the male M22x1.5 rod to drive rigid tooling.
Heavy Lift Lowering
Set precise lower limits for vertical material handling tasks, safely managing loads up to 128.1 kg with a 2:1 margin before hitting the fixed NBR bumper.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-30B the Right Cylinder?
When sizing this 80 mm bore, evaluate both neighbours: stepping down to the SDAJ63 yields 1558.6 N push at 0.5 MPa, while stepping up to the SDAJ100 provides 3927 N. This SDAJ80X55-30B provides a theoretical maximum push of 513 kgf at 1.0 MPa, with a computed safe working load around 1508 N (60% of the 0.5 MPa rating) or a 128.1 kg vertical lift with a 2:1 margin.
Choose this specific model if your assembly line requires frequent on-machine stroke tuning between 25 and 55 mm. It carries the -B male M22x1.5 rod thread and uses a PT3/8 air port. Note that this SKU lacks the -S magnet, so magnetic switches cannot be used. For load holding without live air pressure, you must add an external rod lock or pilot-operated check valve, as the fixed bumper only decelerates and does not lock the piston.
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 SDAJ80X55-30B FAQ
This 80 mm bore 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 at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa.
The M20x1.5 screw mechanically shortens the extend stroke from the 55 mm maximum down to 25 mm. It is a hard stop, not a mid-stroke lock; the cylinder cannot hold a load without air pressure, and the fixed NBR bumper only decelerates the end of stroke.
