This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X100-20S, 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 MALJ32X100-20-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 20 mm, giving a usable end-position window from 80 to 100 mm. This model is discontinued — the direct replacement is the MBLJ32X100-20-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20-S
The AirTAC MALJ32X100-20-S is a discontinued double-acting double-rod mini cylinder with a rear adjustable stroke stopper. The 20 mm adjust code lets you trim the rear position, creating a usable 80-100 mm stroke window without adding external stops. The direct replacement is the MBLJ32X100-20-S, matching the 32 mm bore, 100 mm stroke, G1/8 port, and FA/LB mounting.
This -S SKU includes a magnet for CS1-M or DS1-M switches; the MBLJ upgrade transitions to CMSG/DMSG/EMSG sensors. The MALJ uses threaded covers and a fixed rubber bumper, while the MBLJ uses a riveted rolling-packed body. The adjuster is a travel stop, not a lock, so it sets the end position but will not hold a load without live air pressure.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20-S Technical Specifications
| Model | Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20-S |

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 MBLJ32X100-20-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 MBLJ32X100-20-S matches these values.

Replacement: MALJ → MBLJ. No back-cover (CA/U/CM) and no SDB. Mounting: FA / LB.
Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20-S Is Used
Bottle Capper Reach
Fine-tune the 100 mm extension on a rotary capping turret, shortening the stroke by 20 mm to adapt to varying bottle neck heights without repositioning the cylinder block.
Leak Test Seal Clamp
Apply the 346 N pull force to hold a sealing head against pipe fittings during a 5-second pneumatic leak test, adjusting the end stop to compensate for seal wear.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20-S with MBLJ32X100-20-S
Replace the MALJ32X100-20-S directly with the MBLJ32X100-20-S. Confirm the 32 mm bore, 100 mm stroke, 20 mm adjust code, PT G1/8 port, M10x1.25 rod thread, and FA/LB mounting. Note the sensor swap: your old CS1-M/DS1-M switches must change to CMSG/DMSG/EMSG on the MBLJ. The rear adjuster remains a travel stop, not a lock, so add an external lock for held loads.
Upgrade checklist
- ✓ Order the MBLJ32X100-20-S (same bore/stroke/adjust)
- ✓ Same 80–100 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 MBLJ32X100-20-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X100-20-S FAQ
Yes, the MALJ32X100-20-S is discontinued. The direct replacement is the MBLJ32X100-20-S, matching the 32 mm bore, 100 mm stroke, 20 mm adjust code, and G1/8 port. You will need to upgrade your sensors from the old CS1-M/DS1-M to the CMSG/DMSG/EMSG family.
The usable stroke window is 80-100 mm (100 mm stroke minus the 20 mm adjust code). At 0.7 MPa, push is 563 N. The maximum force is 82 kgf at 1.0 MPa. The adjuster is a travel stop, not a lock.
