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-MBLJ25X75-30S, 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-MALJ25X75-30S
The AirTAC Airtac B01-MALJ Special Application Cylinder B01-MALJ25X75-30S is a double-acting aluminum mini cylinder with a rear adjustable-stroke stopper: you can trim up to 30 mm, giving a usable end-position window from 45 to 75 mm. This model is discontinued — the drop-in replacement is the B01-MBLJ25X75-30S.

About the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X75-30S
The AirTAC B01-MALJ25X75-30S is a discontinued double-acting, single-rod adjustable-stroke mini cylinder. The B01- prefix marks this as an application-dedicated (customer-specified) variant of the base MALJ25X75-30S, meaning it is mechanically identical to the standard catalog model. The 30 mm rear adjuster creates a usable stroke window of 45-75 mm, letting you dial in the exact reach without external stops. It delivers 245 N push and 206 N pull at 0.5 MPa.
The exact drop-in replacement is the MBLJ25X75-30S, which matches the bore, stroke, adjust code, port, and force. Two upgrade details stand out: this MALJ uses threaded covers and a CS1-M / DS1-M magnet sensor system, whereas the MBLJ features a riveted rolling-packed body and uses CMSG / DMSG / EMSG sensors. Remember the adjuster is a travel stop, not a lock; it sets the end position but cannot hold a load without live air. End impact is softened by a fixed rubber bumper, as there is no adjustable air cushion.

Where the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X75-30S Is Used
PCB Router Depth Stop
Dial the 45-75 mm window to set the exact cutting depth on a PCB depaneling router, using the 245 N push force to maintain a consistent plunge without cracking the board.
Textile Loom Tensioner
Fine-tune the guide arm reach on a textile loom, adjusting the stroke on the fly to maintain fabric tension during material roll changes.
Carton Flap Folder
Adjust the end position to accommodate varying box heights on a packaging line, ensuring the 206 N pull force neatly folds flaps without crushing the cardboard.
Replacing the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X75-30S with B01-MBLJ25X75-30S
To replace the B01-MALJ25X75-30S, specify the MBLJ25X75-30S. Confirm the 25 mm bore, 75 mm stroke, 30 mm adjust code, G1/8 port, PT thread, and FA or LB mounting (there is no back cover or SDB option). Because this SKU has the -S magnet, you must upgrade your sensors from the old CS1-M / DS1-M to the MBLJ's CMSG / DMSG / EMSG switches. The rear screw is a travel stop only; use an external lock if you need to hold a load safely without air pressure.
When sizing this 25 mm bore cylinder, step down to a 20 mm bore for lighter loads (157 N push at 0.5 MPa) or step up to a 32 mm bore for heavier tasks (402 N push at 0.5 MPa). At a 75 mm stroke, rod side-load is minimal, but always ensure the load is guided to prevent rod bending.
Upgrade checklist
- ✓ Order the B01-MBLJ25X75-30S (same bore/stroke/adjust)
- ✓ Same 45–75 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-MBLJ25X75-30S instead of this discontinued model.
Airtac B01-MALJ Special Application Cylinder B01-MALJ25X75-30S FAQ
Yes, the B01-MALJ25X75-30S is discontinued. The exact drop-in replacement is the MBLJ25X75-30S, which matches the 25 mm bore, 75 mm stroke, 30 mm adjust code, and force. The B01- prefix simply marks this as an application-dedicated variant of the base MALJ25X75-30S. You will need to switch from CS1-M / DS1-M sensors to CMSG / DMSG / EMSG switches for the new riveted body.
The -30 adjust code means you can trim the rear end position by up to 30 mm, giving a usable stroke window of 45-75 mm. The full force figures for this 25 mm bore are: 245 N push and 206 N pull at 0.5 MPa, 343 N push at 0.7 MPa, and a maximum of 50 kgf at 1.0 MPa. Note that the adjuster is a travel stop, not a lock, and it will not hold a load without live air.
