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-MBLJ25X125-30S, 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-MALJ25X125-30S
The AirTAC Airtac B01-MALJ Special Application Cylinder B01-MALJ25X125-30S 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 95 to 125 mm. This model is discontinued — the drop-in replacement is the B01-MBLJ25X125-30S.

About the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X125-30S
The B01-MALJ25X125-30S is a discontinued double-acting mini cylinder. The B01- prefix marks it as an application-dedicated (customer-specified) variant, mechanically identical to the base MALJ25X125-30S. It delivers 245 N push and 206 N pull at 0.5 MPa. The rear screw lets you trim up to 30 mm, giving a usable 95-125 mm stroke window. The exact drop-in replacement is the MBLJ25X125-30S.
This 25 mm bore uses a G1/8 port and a fixed rubber bumper. The adjuster is a travel stop, not a lock, so it will not hold a load without live air. Upgrading to the MBLJ changes the body from threaded covers to a riveted rolling-packed design, and the -S magnet switches from CS1-M/DS1-M to CMSG/DMSG/EMSG sensors.

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-MBLJ25X125-30S carries the same ratings.
Theoretical Output Force (Ø25mm)

Where the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X125-30S Is Used
PCB Depaneling Saw
Dials the 95-125 mm blade plunge depth precisely. The 245 N push force drives the cut while the rear stop prevents over-travel into the fixture.
Dispenser Valve Height
Fine-tunes the nozzle height on an adhesive potting line. The 30 mm rear trim adjusts the drop distance without machining new brackets.
Leather Skiving Press
Sets the contact depth for a edge-shaving blade. The fixed rubber bumper absorbs the 206 N pull impact at the end of each retract cycle.
Replacing the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X125-30S with B01-MBLJ25X125-30S
To replace this discontinued B01-MALJ25X125-30S, order the MBLJ25X125-30S. Confirm the 25 mm bore, 125 mm stroke, 30 mm adjust code, G1/8 PT port, and FA/LB mounting (no back cover or SDB). The -S magnet requires CMSG/DMSG/EMSG switches on the new body. If you need less force, step down to the 20 mm bore (157 N push at 0.5 MPa). If you need more, step up to the 32 mm bore (402 N push). Remember the adjuster sets the end position but does not hold load without air. At 125 mm stroke, minimize side-load to avoid rod bending.
Upgrade checklist
- ✓ Order the B01-MBLJ25X125-30S (same bore/stroke/adjust)
- ✓ Same 95–125 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-MBLJ25X125-30S instead of this discontinued model.
Airtac B01-MALJ Special Application Cylinder B01-MALJ25X125-30S FAQ
Yes, it is discontinued. The exact drop-in replacement is the MBLJ25X125-30S, matching the 25 mm bore, 125 mm stroke, 30 mm adjust code, and G1/8 port. The B01- prefix only denotes an application-dedicated variant; mechanically it is identical to the base MALJ. The MBLJ upgrades the body to a riveted rolling-packed design and uses CMSG/DMSG/EMSG sensors for the magnet.
The full figure set is 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. The 30 mm adjust code creates a usable stroke window of 95-125 mm. The rear adjuster acts as a travel stop only and does not lock the load without live air pressure.
