Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40B 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 20 to 60 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40B
The AirTAC SDAJ80X60-40B is a double-acting compact cylinder featuring an external extend stop. By turning the R (M20x1.5) adjuster screw, you can dial the forward stroke down by up to 40 mm, yielding a usable extension range of 20 to 60 mm directly on the machine. This on-site tuning eliminates the need for shims or part swaps during commissioning. The adjuster strictly sets the mechanical stop position and does not alter the pneumatic area, meaning force remains identical to a standard SDA of this bore, delivering about 2513.3 N of push at 0.5 MPa.
This specific SKU includes a male-threaded piston rod (M22x1.5) for secure external mounting and operates via a PT3/8 port. Built with a short riveted body, it saves axial mounting depth where a longer cylinder would fail to fit. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this base configuration lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.

The adjustment screw shortens the extend stroke by up to 40 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 SDAJ80X60-40B Is Used
Heavy Press Fitment
Dial the M20x1.5 adjuster to set the exact 20-60 mm extend depth for pressing bearings, leveraging the 2513.3 N push force without swapping physical spacers.
Multi-Size Diverting
Accommodate varying package lengths on a packaging line by tuning the extend stop on the fly, using the compact riveted body to fit tight transfer stations.
Vertical Lift Stops
Control descent in lifting rigs where a 128.1 kg load is raised; set the mechanical stop precisely while relying on external check valves for load holding.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40B the Right Cylinder?
When sizing this model, evaluate your force requirements against neighbouring bores. Dropping down to the SDAJ63 yields 1558.6 N of push at 0.5 MPa, whereas stepping up to the SDAJ100 provides 3927 N. The SDAJ80 sits comfortably in the middle, offering a safe working load of roughly 1508 N (about 60% of its 2513.3 N capacity at 0.5 MPa) and a vertical lift capability of approximately 128.1 kg with a 2:1 safety margin. Choose this 80 mm bore if your changeover routines demand precise, on-site stroke tuning between 20 and 60 mm.
Confirm your parameters before ordering: an 80 mm bore, 60 mm maximum stroke, 40 mm adjustment window, and a PT3/8 air supply. This unit features the -B male M22x1.5 rod end and no magnet. Because a plain double-acting cylinder drifts when air is lost or the valve is centered, the fixed NBR bumper only decelerates the stroke end and does not act as a lock. For suspended or vertical loads that must be held 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 20–60 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 SDAJ80X60-40B FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513.3 N of push and 2267.8 N of pull. At 0.7 MPa, push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push is 513 kgf at 1.0 MPa.
Turning the external R (M20x1.5) screw shortens the forward stroke by up to 40 mm, allowing an extend range of 20 to 60 mm. The screw is strictly a mechanical stop, not a mid-stroke lock, and the cylinder will drift if air pressure is lost.
