This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL40X125SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL40X125SU in place of this model. The MBL replacement upgrades to a riveted rolling-packed body and the current CMSG / DMSG / EMSG sensor switches (the MAL used CS1-M / DS1-M).
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X125SU
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL40X125SU is a double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 125mm stroke, G1/4 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL40X125SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X125SU
The AirTAC B01-MAL40X125SU is a discontinued, double-acting aluminum mini round cylinder delivering 628 N of push force at 0.5 MPa. The B01- prefix marks this as an application-dedicated, customer-specified variant of the standard MAL40X125SU, meaning it is mechanically identical to the base model. AirTAC replaced the legacy MAL line with the MBL series, making the MBL40X125SU the exact drop-in replacement. It shares the same 40 mm bore, 125 mm stroke, G1/4 port, and flat-end U back cover.
This SKU features a built-in -S magnet for position detection. On the older MAL body—which uses threaded front and back covers—the magnet pairs with legacy CS1-M or DS1-M switches. When upgrading to the riveted rolling-packed MBL body, the sensor family changes to the current CMSG, DMSG, or EMSG switches. The carbon-steel rod has a 20 um hard-chrome plating and rides on a self-lubricating front-cover bearing guide, while a heterogeneous two-way seal retains grease for a long service life.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL40X125SU carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The B01-MBL40X125SU produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X125SU Is Used
Carton Flap Folding
Provides 628 N of push force at 0.5 MPa to cleanly fold heavy cardboard flaps on high-speed packaging conveyors without buckling.
Press Fit Bushings
Delivers consistent 528 N pull force to seat bronze bushings into machined housings on an automated tooling line, relying on the 125 mm stroke.
Pallet Stopper Gate
Acts as a rigid physical stop for loaded pallets using the U flat-end cover, absorbing the impact via the fixed rubber bumper.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL40X125SU with B01-MBL40X125SU
To replace this discontinued cylinder, order the MBL40X125SU. Confirm the 40 mm bore, 125 mm stroke, G1/4 port, and default PT tapered thread are retained. The U flat-end back cover provides a rigid rear mount, so ensure your mounting surface is perfectly square to avoid rod binding. Because this SKU includes the -S magnet, note that your existing CS1-M or DS1-M switches must be swapped to CMSG, DMSG, or EMSG sensors to fit the MBL body.
When sizing, verify if 628 N push (528 N pull) at 0.5 MPa is optimal. Stepping down to the 32 mm neighbor yields 402 N of push force, while stepping up is not an option as 40 mm is the largest MAL bore. The fixed rubber bumper softens end-of-stroke impacts but cannot hold a load; if air pressure drops, the rod will drift unless you add an external rod lock or pilot-operated check valve. If your application needs precise end-of-stroke deceleration, upgrade to the MBLC variant which adds an adjustable air cushion the MAL lacks.
Upgrade checklist
- ✓ Order the B01-MBL40X125SU (same bore/stroke/force)
- ✓ Same G1/4 port and mounting accessories
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ Need a cushion? use MBLC (adjustable air cushion)
- ✓ Confirm back cover (CA / U) and thread (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.1 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not intended for field disassembly.
- check Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U / CM).
- check For new builds, specify the B01-MBL40X125SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL40X125SU FAQ
Yes, the B01-MAL40X125SU is discontinued. The exact drop-in replacement is the MBL40X125SU, which matches the 40 mm bore, 125 mm stroke, G1/4 port, and U flat-end cover. The B01- prefix simply designated an application-specific build of the standard MAL cylinder, so the MBL fits identically.
At 0.5 MPa, the push force is 628 N and pull is 528 N. At 0.7 MPa, push is 880 N, with a theoretical max of 128 kgf at 1.0 MPa. Because this SKU has the -S magnet, it uses older CS1-M or DS1-M switches; the MBL replacement requires CMSG, DMSG, or EMSG sensors.
