Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30B
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30B 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 10 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30B
The AirTAC SDAJ80X40-30B is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M20x1.5) screw, you can dial the forward stroke down from its 40 mm maximum to as little as 10 mm directly on the machine, eliminating the need for shims or 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 specific SKU includes a male-threaded piston rod (M22x1.5) for secure external mounting and uses a PT3/8 air port. The short riveted body saves valuable axial mounting depth where a larger profile cylinder would not fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 40 mm |
| Adjustable range | 10 – 40 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 SDAJ80X40-30B Is Used
Heavy Press Fitment
Dial in the 10-40 mm extend stop on the factory floor to precisely seat heavy bearings, utilizing the 2513.3 N push force without over-traveling.
Vertical Lift Stops
Securely raise 128.1 kg loads using the male M22x1.5 rod, adjusting the mechanical stop to prevent collision at the upper workstation bounds.
Changeover Tooling
Quickly reconfigure the extend position for new product runs by turning the M20x1.5 adjuster, saving axial space in tight multi-model assembly cells.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X40-30B the Right Cylinder?
When sizing this 80 mm bore actuator, evaluate the neighbouring bores using 0.5 MPa push figures: stepping down to the SDAJ63 yields 1558.6 N, while stepping up to the SDAJ100 provides 3927 N. This model delivers a robust 2513.3 N at 0.5 MPa, translating to a safe working load of roughly 1508 N (about 60 percent of capacity) and a vertical lift capability of approximately 128.1 kg with a 2:1 safety margin. Choose this unit if your fixture requires on-site stroke tuning between 10 and 40 mm.
Confirm the 80 mm bore, 40 mm maximum stroke, 30 mm adjustment window, PT3/8 port, and the male M22x1.5 rod thread. Note that this SKU lacks a piston magnet (-S), so it cannot accept reed or electronic switches. Furthermore, a standard cylinder does not hold position if air pressure drops or the valve is centred; for load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–40 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 SDAJ80X40-30B FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513.3 N of push force and 2267.8 N of pull force. At 0.7 MPa, push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push force is 513 kgf at 1.0 MPa.
The external M20x1.5 screw mechanically shortens the extend stroke from 40 mm down to 10 mm without altering the force. This adjuster is a stop, not a lock; the cylinder will drift if air is lost. For load holding, use an external rod lock or pilot-operated check valve.
