Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40SB 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 SDAJ80X60-40SB
The AirTAC SDAJ80X60-40SB is a compact double-acting single-rod cylinder built for tight axial footprints, utilizing a riveted body design that saves mounting depth where larger profile variants fail to fit. An external M20x1.5 adjustment screw lets you dial the extend stop directly on the machine, shortening the forward stroke by up to 40 mm to yield a usable 20-60 mm range without swapping shims or components.
Because the adjuster purely sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, generating 2513.3 N of push at 0.5 MPa. This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches and a male M22x1.5 threaded rod end for secure external mounting.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 60 mm |
| Adjustable range | 20 – 60 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 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 SDAJ80X60-40SB Is Used
Heavy Press Fit Tuning
Dial in the exact 20-60 mm extend stop on the M20x1.5 screw during press assembly setup, leveraging the 2513.3 N push force to seat bearings without over-traveling.
Vertical Lift Positioning
Raise components up to 128.1 kg with a 2:1 safety margin, fine-tuning the drop height on-site to accommodate varying payload dimensions without changing parts.
Changeover-Intensive Lines
Rapidly adjust the forward stroke for different product formats, using the male M22x1.5 rod thread to securely attach changeable tooling while maintaining compact depth.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X60-40SB the Right Cylinder?
When sizing this 80 mm bore, evaluate both neighbors: stepping down to the SDAJ63 yields 1558.6 N push at 0.5 MPa, while stepping up to the SDAJ100 provides 3927 N. The SDAJ80X60-40SB is ideal for applications requiring on-machine stroke tuning during frequent changeovers, delivering a safe working load around 1508 N (roughly 60% of its 0.5 MPa rating) or a vertical lift capacity of 128.1 kg with a 2:1 safety margin.
Confirm the 80 mm bore, 60 mm max stroke, 40 mm adjust window, PT3/8 port, male M22x1.5 rod thread, and the -S magnet for your setup. Remember that a plain cylinder does not hold position if air is lost or the valve centers; the fixed NBR bumper only decelerates near the end of travel. For secure 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 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 SDAJ80X60-40SB FAQ
This double-acting cylinder delivers 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 at 30-500 mm/s, accepts up to 1.0 MPa operating pressure, and functions between -20 and +70 C.
The external M20x1.5 screw shortens the extend end-position by up to 40 mm, allowing the stroke to be set anywhere between 20 and 60 mm on the machine. The included -S magnet enables position sensing with AirTAC reed or electronic switches, while the fixed NBR bumper decelerates the stroke end without acting as a mid-stroke lock.
