This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is B01-MBL32X25CA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the B01-MBL32X25CA 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-MAL32X25CA
The AirTAC Airtac B01-MAL Special Purpose Cylinder B01-MAL32X25CA is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 25mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the B01-MBL32X25CA, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL32X25CA
The AirTAC B01-MAL32X25CA is a discontinued double-acting aluminum mini round cylinder. The leading "B01-" prefix indicates an application-dedicated (customer-specified) variant, meaning it is mechanically identical to the standard MAL32X25CA. Delivering 402 N of push force at 0.5 MPa, it uses a Ø12 mm carbon-steel rod with 20 um hard-chrome plating and a self-lubricating front-cover bearing guide. AirTAC replaced this legacy unit with the MBL32X25CA, a drop-in alternative retaining the exact bore, stroke, port, and CA pivot mount.
This 32 mm bore unit features a G1/8 port and a fixed rubber bumper. A key upgrade in the MBL successor is the transition from threaded front and back covers to a riveted rolling-packed body. Because this specific SKU lacks the -S magnet option, it cannot accept a position sensor. The heterogeneous two-way grease-retaining seal ensures lasting internal lubrication for its compact operational envelope.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The B01-MBL32X25CA carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The B01-MBL32X25CA 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-MAL32X25CA Is Used
PCB Drill Bit Changer
Actuates a short 25 mm stroke to swap tooling in automated PCB drilling spindles, using the 402 N push force to positively seat the bit.
Connector Insertion Press
Pushes IC sockets into printed circuit boards with precise 32 mm bore thrust, relying on the CA pivot to self-align during the press fit.
Carton Flap Folder
Tucks small corrugated box flaps on a packaging line, where the compact 25 mm stroke and self-lubricating bearing handle rapid cycling.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL32X25CA with B01-MBL32X25CA
To replace the B01-MAL32X25CA, order the MBL32X25CA. It drops in directly with the same 32 mm bore, 25 mm stroke, G1/8 port, PT thread, and CA pivot back cover. The CA clevis mount swings on a pin to safely absorb arcing rod movements. If you need to adjust the bore size, stepping down to the 25 mm bore yields 245 N push at 0.5 MPa, while stepping up to the 40 mm bore provides 628 N push at 0.5 MPa and upgrades the port to G1/4. Since this SKU lacks a magnet, no sensor can be fitted; if position detection is required, specify an MBL32X25SCA and migrate to the current CMSG or DMSG switch family. Note that the fixed rubber bumper softens end-of-stroke impacts but does not lock the rod; if air pressure drops, the load will drift unless an external rod lock is installed. For end-of-stroke deceleration control, look to the current MBLC line which offers an adjustable air cushion.
Upgrade checklist
- ✓ Order the B01-MBL32X25CA (same bore/stroke/force)
- ✓ Same G1/8 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-MBL32X25CA instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL32X25CA FAQ
Yes, the B01-MAL32X25CA is discontinued. The exact drop-in replacement is the MBL32X25CA. It shares the same 32 mm bore, 25 mm stroke, G1/8 port, and CA pivot mounting. The primary physical change is that the older threaded body covers were replaced by a riveted rolling-packed body on the MBL.
At 0.5 MPa it provides 402 N push and 346 N pull. At 0.7 MPa push increases to 563 N, with a maximum theoretical force of 82 kgf at 1.0 MPa. It cannot hold position when air is lost; the fixed rubber bumper only softens the stroke end and is not a lock.
