This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X170-100-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 MALJ32X170-100-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-100-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 100 mm, giving a usable end-position window from 70 to 170 mm. This model is discontinued — the direct replacement is the MBLJ32X170-100-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-100-S
The AirTAC MALJ32X170-100-S is a discontinued double-acting double-rod cylinder with a rear adjustable stroke stopper. The 100 mm adjust code trims the rear position, creating a usable stroke window of 70-170 mm. The direct replacement is the MBLJ32X170-100-S, matching the 32 mm bore, 170 mm stroke, and G1/8 port.
This unit features a fixed rubber bumper and a heterogeneous grease-retaining seal. The -S magnet uses older CS1-M / DS1-M switches, whereas the MBLJ upgrade uses CMSG / DMSG / EMSG sensors. The MALJ has threaded covers, while the MBLJ replacement uses a riveted rolling-packed body. The adjuster sets the end position but does not hold load without live air.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-100-S Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-100-S |
|---|---|
| Series | MALJ adjustable-stroke mini cylinder (discontinued) |
| Replacement | MBLJ32X170-100-S |
| Bore size | Ø32 mm |
| Stroke | 170 mm |
| Adjustable window | 70 – 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 |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 500 mm |
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 MBLJ32X170-100-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 MBLJ32X170-100-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-100-S Is Used
Thermoform Plug Assist
Fine-tune the forming depth on a thermoforming press by trimming the stroke up to 100 mm, ensuring consistent plastic sheet stretch before the fixed rubber bumper absorbs the end impact.
Carton Flap Folder
Adjust the rear stop on a packaging line flap folder to handle varying carton heights, relying on the 346 N pull force to retract the folding arm cleanly.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X170-100-S with MBLJ32X170-100-S
To replace this MALJ32X170-100-S, order the direct replacement MBLJ32X170-100-S. Confirm the 32 mm bore, 170 mm stroke, 100 mm adjust code, PT thread, and FA or LB mounting (no back cover or SDB). The -S magnet requires switching from CS1-M / DS1-M to CMSG / DMSG / EMSG sensors. The adjuster is a travel stop, not a lock. At 170 mm stroke, watch for rod-bending under side loads.
Upgrade checklist
- ✓ Order the MBLJ32X170-100-S (same bore/stroke/adjust)
- ✓ Same 70–170 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 MBLJ32X170-100-S instead of this discontinued model.
