This model is discontinued
AirTAC has phased out the MALJ series. You can still order this code here: we ship the drop-in replacement B01-MBLJ25X100-50S, 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 B01-MALJ Special Application Cylinder B01-MALJ25X100-50S
The AirTAC Airtac B01-MALJ Special Application Cylinder B01-MALJ25X100-50S 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 50 to 100 mm. This model is discontinued — the drop-in replacement is the B01-MBLJ25X100-50S.

About the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X100-50S
The B01-MALJ25X100-50S is an application-dedicated (customer-specified) variant of the AirTAC MALJ25X100-50S. The B01- prefix designates a customer-specific build that is mechanically identical to the base model. This discontinued double-acting mini cylinder features a 25mm bore, a 10mm rod, and a rear screw stopper that trims up to 50mm of travel. This yields a usable stroke window of 50-100mm. It delivers 245N push and 206N pull at 0.5MPa.
The exact drop-in replacement is the MBLJ25X100-50S, matching the bore, stroke, adjust code, and G1/8 port. Remember that the rear adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. The original MALJ uses threaded covers and a CS1-M/DS1-M magnet, whereas the MBLJ upgrade features a riveted rolling-packed body and CMSG/DMSG/EMSG sensors. End impact is softened by a fixed rubber bumper, as there is no air cushion.

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 B01-MBLJ25X100-50S carries the same ratings.
Theoretical Output Force (Ø25mm)

Where the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X100-50S Is Used
PCB Router Z-Axis Depth
Dial the rear stopper to set a precise 75mm down-feed on a PCB depaneling router, using the 245N push force to plunge without crushing the substrate.
Carton Flap Folding Arm
Adjust the end position on the fly for varying box heights, using the 50-100mm travel window to fold corrugated flaps cleanly at 0.5MPa.
Aluminum Extrusion Press
Fine-tune the 100mm reach to seat extrusion blanks into the heating chamber, relying on the fixed rubber bumper to soften the 206N retraction impact.
Replacing the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X100-50S with B01-MBLJ25X100-50S
To replace the B01-MALJ25X100-50S with the MBLJ25X100-50S, confirm the 25mm bore, 100mm stroke, 50mm adjust code, PT G1/8 port, and M10x1.25 rod thread. Mounting is limited to FA or LB (no back cover or SDB). The -S magnet changes sensor families from CS1-M/DS1-M to CMSG/DMSG/EMSG. If sizing this 25mm bore (245N push at 0.5MPa), stepping down to the 20mm bore yields 157N push, while stepping up to the 32mm bore provides 402N push. At 100mm stroke, keep the cylinder adequately supported to prevent rod bending and side-load wear.
Upgrade checklist
- ✓ Order the B01-MBLJ25X100-50S (same bore/stroke/adjust)
- ✓ Same 50–100 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 B01-MBLJ25X100-50S instead of this discontinued model.
Airtac B01-MALJ Special Application Cylinder B01-MALJ25X100-50S FAQ
Yes, it is discontinued. The exact drop-in replacement is the MBLJ25X100-50S, which matches the 25mm bore, 100mm stroke, 50mm adjust code, and G1/8 port. The B01- prefix simply marks this as an application-dedicated variant of the base MALJ25X100-50S, so the replacement is mechanically identical.
The usable stroke window is 50-100mm, set by trimming the rear stopper up to 50mm. The force output is 245N push and 206N pull at 0.5MPa, 343N push at 0.7MPa, and a maximum of 50kgf at 1.0MPa. The adjuster is a travel stop only and does not hold the load without air pressure.
