This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X170U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X170U 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 MAL32 Aluminum Alloy Mini Air Cylinder MAL32X170U
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X170U is a double-acting aluminum-barrel mini round cylinder with a Ø32mm bore and 170mm stroke, G1/8 air ports and a fixed rubber bumper. This model is discontinued — the drop-in replacement is the MBL32X170U, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X170U
The AirTAC MAL32X170U is a discontinued double-acting aluminum mini round cylinder featuring a 32 mm bore and 170 mm stroke. It delivers 402 N of push force and 346 N of pull force at 0.5 MPa, utilizing a G1/8 port and a 12 mm hard-chrome plated carbon-steel rod. The exact drop-in replacement is the MBL32X170U, which matches the original bore, stroke, output force, port size, and U flat-end mounting. The legacy MAL uses threaded front and back covers, whereas the current MBL features a riveted rolling-packed body for equally robust performance.
Because this specific SKU lacks an -S magnet, it cannot accommodate a position sensor. The cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion. To manage internal friction over its travel, the piston employs a heterogeneous two-way seal that retains grease, paired with a self-lubricating guide bearing in the front cover.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X170U 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 MBL32X170U 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 MAL32 Aluminum Alloy Mini Air Cylinder MAL32X170U Is Used
Pouch Sealing Press
Provides 402 N of push force at 0.5 MPa to close heated sealing bars on vertical form-fill-seal packaging equipment.
PCB Router Clamp
Secures printed circuit board panels during routing, using the 170 mm stroke to feed material into the cutting spindle.
Carton Flap Folder
Actuates mechanical arms at 30-800 mm/s to tuck minor flaps on small secondary packaging cartons prior to tape sealing.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X170U with MBL32X170U
To replace the MAL32X170U, order the MBL32X170U, ensuring you retain the PT tapered port thread and the U flat-end back cover for rigid mounting. If your application requires position detection, you must step up to an MBL32X170US SKU and migrate from the legacy CS1-M / DS1-M switches to the current CMSG / DMSG / EMSG sensor family. If a precise adjustable air cushion is needed for heavier loads, look at the MBLC equivalent on the current line, as the MAL only offers a fixed rubber bumper.
For sizing flexibility, stepping down to a 25 mm bore reduces the push force to 245 N at 0.5 MPa, while stepping up to a 40 mm bore increases it to 628 N. At 170 mm of stroke, the 12 mm rod is susceptible to bending under lateral stress; use an external guide rail or a pivot bracket to absorb side loads. Note that a plain MBL does not hold its position if air pressure drops—the bumper softens the stroke but does not function as a mechanical lock.
Upgrade checklist
- ✓ Order the MBL32X170U (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 MBL32X170U instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X170U FAQ
Yes, the MAL32X170U is discontinued. The exact drop-in replacement is the AirTAC MBL32X170U, offering the same 32 mm bore, 170 mm stroke, G1/8 port, and U flat-end mounting. The MBL upgrades the body to a riveted rolling-packed design from the original threaded covers.
At 0.5 MPa, the push force is 402 N and pull is 346 N. At 0.7 MPa, push is 563 N, with a maximum theoretical force of 82 kgf at 1.0 MPa. Because this SKU lacks an -S magnet, it cannot take a position sensor; the -S version uses older CS1-M / DS1-M switches, while the MBL replacement uses CMSG / DMSG / EMSG sensors.
