This model is discontinued
AirTAC has phased out the MAL series. You can still order this code here: we ship the direct replacement B01-MBL32X175U, 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-MAL32X175U
The AirTAC B01-MAL Special Purpose Cylinder B01-MAL32X175U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 175mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the direct replacement is the B01-MBL32X175U, which matches its bore, stroke, force and mounting.

About the Airtac B01-MAL Special Purpose Cylinder B01-MAL32X175U
The AirTAC B01-MAL32X175U is a discontinued double-acting aluminum mini round cylinder delivering 402 N of push force at 0.5 MPa. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant of the base MAL32X175U; mechanically, it shares the exact same 32 mm bore, 175 mm stroke, G1/8 port, and physical specs as the standard model. AirTAC replaced this legacy line with the MBL32X175U, a direct alternative retaining the same output force, porting, and mounting interface.
This SKU features a U flat-end back cover for rigid alignment and lacks a -S magnet, meaning it cannot accept a position sensor. The legacy MAL body relies on threaded front and rear covers, whereas the newer MBL utilizes a riveted rolling-packed body. Internally, a heterogeneous two-way seal retains grease, and the carbon-steel rod features a 20 um hard-chrome plating to resist wear. End-of-stroke deceleration is handled by a fixed rubber bumper, not an adjustable air cushion.

Where the Airtac B01-MAL Special Purpose Cylinder B01-MAL32X175U Is Used
PCB Depaneling Router Gate
Actuates a safety access gate on a PCB depaneling router, using the 175 mm stroke to clear the work area while the 402 N push force at 0.5 MPa ensures positive closure against light machine vibration.
Carton Flap Folder
Drives a mechanical arm that tucks minor flaps on small packaging cartons prior to tape sealing, where the rigid U flat-end cover maintains bracket alignment during rapid 30-800 mm/s cycling.
Diagnostic Reagent Tray Ejector
Pushes loaded reagent trays out of a clinical analyzer nesting station, benefiting from the grease-retaining two-way seal that prevents contamination in cleanroom-adjacent environments.
Replacing the Airtac B01-MAL Special Purpose Cylinder B01-MAL32X175U with B01-MBL32X175U
To replace the B01-MAL32X175U, order the MBL32X175U. Confirm your 32 mm bore, 175 mm stroke, G1/8 port, and PT thread. The U flat-end back cover provides rigid mounting, so ensure your mechanical setup does not induce severe misalignment. Because this SKU lacks an -S magnet, no position sensor can be fitted. If you require end-of-stroke detection on the new MBL, add the -S option and note that the sensor family changes from the older CS1-M / DS1-M to the current CMSG / DMSG / EMSG switches.
For sizing flexibility, 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. The 175 mm stroke is well within standard limits, but the 12 mm rod has low side-load tolerance; use an external guide to prevent rod bending. The fixed rubber bumper softens impacts, but if your load requires adjustable cushioning, look at the MBLC variant on the current line. A plain cylinder does not hold position upon air loss—install a pilot-operated check valve if drift is unacceptable.
Upgrade checklist
- ✓ Order the B01-MBL32X175U (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-MBL32X175U instead of this discontinued model.
Airtac B01-MAL Special Purpose Cylinder B01-MAL32X175U FAQ
Yes, the B01-MAL32X175U is discontinued. The direct replacement is the MBL32X175U, which matches the 32 mm bore, 175 mm stroke, G1/8 port, and U flat-end mounting. The "B01-" prefix simply designated an application-specific build of the standard MAL32X175U, so the MBL replaces it perfectly.
The full force set is 402 N push and 346 N pull at 0.5 MPa, 563 N push at 0.7 MPa, and a maximum of 82 kgf at 1.0 MPa. Because this specific SKU lacks the -S magnet, it cannot accept a position sensor; the older MAL -S versions used CS1-M / DS1-M switches, while the MBL replacement uses CMSG / DMSG / EMSG sensors.
