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-MBLJ25X70-30S, 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-MALJ25X70-30S
The AirTAC Airtac B01-MALJ Special Application Cylinder B01-MALJ25X70-30S 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 40 to 70 mm. This model is discontinued — the drop-in replacement is the B01-MBLJ25X70-30S.

About the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X70-30S
The AirTAC B01-MALJ25X70-30S is a discontinued double-acting mini cylinder with a 30 mm rear adjustable stroke. The B01- prefix marks this as an application-dedicated (customer-specified) variant of the base MALJ25X70-30S, mechanically identical to the standard model. The 30 mm adjuster creates a usable extension window of 40-70 mm. At 0.5 MPa it delivers 245 N push and 206 N pull force.
The exact drop-in replacement is the MBLJ25X70-30S, sharing the same 25 mm bore, G1/8 port, and 50 kgf max force. Two upgrade facts apply: this MALJ uses threaded covers and CS1-M / DS1-M sensors, while the MBLJ features a riveted rolling-packed body and CMSG / DMSG / EMSG switches. The rear 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, not an adjustable air cushion.

Where the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X70-30S Is Used
PCB Depaneling Saw Stop
Dials the blade approach depth precisely within the 40-70 mm window. The 245 N push force at 0.5 MPa provides consistent positioning without crushing the board edge.
Dispenser Nozzle Height Trim
Fine-tunes the Z-axis rest position for different adhesive viscosities. The 30 mm rear stop lets operators change dispense height without adding external shims.
Connector Pin Insertion
Sets the exact bottoming depth for delicate pin pressing. The fixed rubber bumper absorbs the end impact, protecting the 10 mm rod and connector housing.
Replacing the Airtac B01-MALJ Special Application Cylinder B01-MALJ25X70-30S with B01-MBLJ25X70-30S
To replace this B01-MALJ25X70-30S with the MBLJ25X70-30S, confirm the 25 mm bore, 70 mm stroke, 30 mm adjust code, G1/8 PT thread, and FA/LB mounting. There is no back cover or SDB option. The -S magnet changes sensor families from CS1-M / DS1-M to CMSG / DMSG / EMSG. Remember the adjuster is a stop, not a lock.
When sizing, you can step down to the 20 mm bore for tighter spaces (157 N push at 0.5 MPa) or step up to the 32 mm bore for heavier loads (402 N push at 0.5 MPa). At 70 mm stroke, rod side-load is minimal, but always guide the load to prevent rod bending.
Upgrade checklist
- ✓ Order the B01-MBLJ25X70-30S (same bore/stroke/adjust)
- ✓ Same 40–70 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-MBLJ25X70-30S instead of this discontinued model.
Airtac B01-MALJ Special Application Cylinder B01-MALJ25X70-30S FAQ
Yes, the B01-MALJ25X70-30S is discontinued. The exact drop-in replacement is the MBLJ25X70-30S. The B01- prefix simply marks an application-dedicated variant, so the replacement matches the 25 mm bore, 70 mm stroke, 30 mm adjuster, and G1/8 port exactly. You will need to upgrade your sensors from CS1-M / DS1-M to CMSG / DMSG / EMSG.
The 30 mm adjuster creates a usable stroke window of 40-70 mm. The full force figures for the 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. The rear screw acts as a travel stop to set this position, but it is not a lock and cannot hold the load without continuous air pressure.
