This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the direct replacement MBLJ32X500-50-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 MALJ32X500-50-S
The AirTAC Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-50-S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 50 mm, giving a usable end-position window from 450 to 500 mm. This model is discontinued — the direct replacement is the MBLJ32X500-50-S.

About the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-50-S
The AirTAC MALJ32X500-50-S is a discontinued double-acting double-rod cylinder with a rear adjustable stroke stopper. It provides a usable stroke window of 450-500 mm, letting you trim up to 50 mm at the rear without external stops. The direct replacement is the MBLJ32X500-50-S, which matches the bore, stroke, adjuster code, G1/8 port, and mounting.
This -S SKU includes a magnet for position sensing. The older MALJ uses CS1-M or DS1-M switches, while the MBLJ upgrade moves to CMSG, DMSG, or EMSG sensors. The original MALJ features threaded covers, whereas the MBLJ uses a riveted rolling-packed body. Impact is absorbed by a fixed rubber bumper, as there is no adjustable air cushion. The rear adjuster sets the end position but is a travel stop, not a lock; it will not hold a load without live air pressure.

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 MBLJ32X500-50-S carries the same ratings.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

| 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 MBLJ32X500-50-S matches these values.

Where the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-50-S Is Used
Carton Flap Folding
Dials the exact 450-500 mm reach on packaging lines to fold varying corrugated carton flaps without repositioning the cylinder bracket.
Long-Reach Transfer Arm
Extends a lightweight transfer arm 500 mm to move parts between conveyor belts, using the 50 mm rear trim to fine-tune the drop-off point.
Replacing the Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-50-S with MBLJ32X500-50-S
To replace this MALJ32X500-50-S, order the MBLJ32X500-50-S. Confirm the 32 mm bore, 500 mm stroke, 50 mm adjust code, G1/8 PT port, and M10x1.25 rod-end thread. Mounting is Basic, FA, or LB only, as there is no back-cover or SDB option. Note the -S magnet changes sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG. At 500 mm of stroke, minimize side-load to prevent rod bending and premature seal wear. The adjuster is a stop, not a lock, so add an external locking device for held loads.
Upgrade checklist
- ✓ Order the MBLJ32X500-50-S (same bore/stroke/adjust)
- ✓ Same 450–500 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 MBLJ32X500-50-S instead of this discontinued model.
Airtac MALJ32 Adjustable Mini Cylinder MALJ32X500-50-S FAQ
Yes, the MALJ32X500-50-S is discontinued. The direct replacement is the MBLJ32X500-50-S, which matches the 32 mm bore, 500 mm stroke, 50 mm adjust code, and G1/8 port. The MBLJ upgrades the body to a riveted rolling-packed design and changes the magnet sensors from CS1-M/DS1-M to CMSG/DMSG/EMSG.
The -50 adjust code is a rear travel stop that lets you shorten the end position by up to 50 mm, creating a 450-500 mm usable stroke window. It is a stop, not a lock, and cannot hold a load without air pressure.
