This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL32X20SU, with the same bore, stroke, output force, port and mounting, so it fits the same application. 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-MAL32X20SU
The AirTAC B01-MAL Special Purpose Cylinder B01-MAL32X20SU is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 20mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL32X20SU, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL32X20SU
The AirTAC B01-MAL32X20SU is a discontinued compact double-acting aluminum mini round cylinder. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant of the base MAL32X20SU, meaning it is mechanically identical to the standard catalog model but grouped for a specific industry build. Delivering 402 N of push force at 0.5 MPa, it is now replaced by the direct replacement MBL32X20SU, which matches the 32 mm bore, 20 mm stroke, G1/8 port, and U flat-end back cover exactly.
This legacy unit features a Ø12 mm carbon-steel rod with 20 um hard-chrome plating guided by a self-lubricating front-cover bearing. The original MAL body used threaded front and back covers, whereas the current MBL replacement utilizes a riveted rolling-packed body. Because this SKU includes the -S magnet, it was designed to work with the older CS1-M / DS1-M switches; upgrading to the MBL means the sensor family changes to CMSG / DMSG / EMSG.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL32X20SU Is Used
PCB Depaneling Ejector
Uses the 20 mm short stroke and 402 N push force to eject cut circuit boards from a routing fixture without overshooting the tight machine envelope.
Connector Insertion Press
Provides the precise 346 N pull force and rigid U flat-end mounting needed to seat ribbon connectors into PCB headers during automated assembly.
Carton Flap Tucker
Relies on the compact 32 mm aluminum body and 563 N push at 0.7 MPa to fold small corrugated box flaps prior to tape sealing in packaging lines.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL32X20SU with B01-MBL32X20SU
To replace the B01-MAL32X20SU, order the MBL32X20SU. It is a direct swap: the 32 mm bore yields 402 N push and 346 N pull at 0.5 MPa, the port remains G1/8, and the U flat-end back cover provides rigid rear mounting. Confirm your PT thread form and note the -S magnet sensor change from CS1-M / DS1-M to CMSG / DMSG / EMSG. If you need to step down, the 25 mm bore offers 245 N push at 0.5 MPa; stepping up to the 40 mm bore provides 628 N push at 0.5 MPa. The MAL uses a fixed rubber bumper, so if your application requires adjustable end-cushioning, look at the MBLC line. Remember that a plain cylinder does not hold position if air pressure drops.
Upgrade checklist
- ✓ Order the B01-MBL32X20SU (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-MBL32X20SU instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL32X20SU FAQ
Yes, the B01-MAL32X20SU is discontinued. The direct replacement is the MBL32X20SU, which matches the 32 mm bore, 20 mm stroke, G1/8 port, and U flat-end cover. The "B01-" prefix simply designated an application-specific build of the standard MAL32X20SU, so the MBL fits identically.
At 0.5 MPa it provides 402 N push and 346 N pull. At 0.7 MPa push is 563 N, and the maximum theoretical force is 82 kgf at 1.0 MPa. Because this SKU has the -S magnet, it uses the older CS1-M / DS1-M switches; the MBL replacement requires the current CMSG / DMSG / EMSG sensor family.
