This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X170-75-S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The MBLJ replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-75-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-75-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 75 mm, giving a usable end-position window from 95 to 170 mm. This model is discontinued — the direct replacement is the MBLJ32X170-75-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-75-S
The AirTAC MALJ32X170-75-S is a discontinued double-acting double-rod cylinder with a 32mm bore and a 170mm stroke. A rear screw lets you trim up to 75mm, giving a usable window of 95-170mm to dial in the exact end position. The direct replacement is the MBLJ32X170-75-S, matching the bore, stroke, force, and port.
This -S variant carries a magnet for the older CS1-M / DS1-M switches, whereas the MBLJ upgrade uses CMSG / DMSG / EMSG sensors. The original MAL features threaded covers, while the MBL uses a riveted rolling-packed body. Both use a fixed rubber bumper, not an air cushion. The rear adjuster is a travel stop that sets depth but does not hold load without live air.

| Stroke | 170 mm |
| Adjustable window | 95 – 170 mm |
| Acting type | Double acting, adjustable stroke |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.1 – 1.0 MPa |

The rear adjuster is a travel stop, not a lock — it sets the end position but does not hold the load without live air. No back-cover code and no SDB on adjustable-stroke. The MBLJ32X170-75-S carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
MALJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod MAL push of the same bore. The MBLJ32X170-75-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-75-S Is Used
Aluminum Extrusion Notching
Fine-tune the rear travel stop to position a notching saw blade precisely on aluminum profiles, preventing over-travel and tool damage on varying extrusion lengths.
Carton Flap Folding
Adjust the end position on the fly to fold varying carton heights on a packaging line, letting the cylinder retract cleanly without slamming the rear bumper.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-75-S with MBLJ32X170-75-S
To replace this MALJ32X170-75-S, specify the MBLJ32X170-75-S and confirm the 32mm bore, 170mm stroke, 75mm adjust code, G1/8 port, PT threads, and FA or LB mounting (no back cover or SDB). Swap the CS1-M / DS1-M sensors for CMSG / DMSG / EMSG switches. At 170mm stroke, guard against rod bending by minimizing side loads on the extended rod.
Upgrade checklist
- ✓ Order the MBLJ32X170-75-S (same bore/stroke/adjust)
- ✓ Same 95–170 mm adjustable window
- ✓ Adjuster is a stop, not a lock
- ✓ No back cover / SDB — plan an FA/LB mount
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check The rear adjuster sets the end position — it is not a load lock.
- check No back-cover / SDB on adjustable-stroke — use FA / LB.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the MBLJ32X170-75-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-75-S FAQ
Yes, the MALJ32X170-75-S is discontinued. The direct replacement is the MBLJ32X170-75-S, which matches the 32mm bore, 170mm stroke, 75mm adjust code, and G1/8 port. You will need to upgrade your sensors from the older CS1-M / DS1-M switches to the CMSG / DMSG / EMSG family.
The -75 code means you can trim up to 75mm at the rear, creating a usable stroke window of 95-170mm. This adjuster is a travel stop, not a lock, so it will not hold a load without live air.
