This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is MBL32X170SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the MBL32X170SU 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 MAL32X170SU
The AirTAC Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X170SU 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 MBL32X170SU, which matches its bore, stroke, force and mounting.

About the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X170SU
The AirTAC MAL32X170SU 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. The exact drop-in replacement is the MBL32X170SU, which matches the original bore, stroke, output force, G1/8 port, and U flat-end back cover. You can install the MBL without modifying your existing mounting layout.
This legacy unit utilizes a fixed rubber bumper to soften end-of-stroke impacts, whereas the current MBLC line offers an adjustable air cushion if you need finer deceleration. The older MAL body uses threaded front and back covers, while the MBL upgrade features a riveted rolling-packed barrel for equally rigid alignment. Inside, a heterogeneous two-way seal retains grease, and the 12 mm carbon-steel rod is protected by 20 um hard-chrome plating. Because this SKU includes the -S magnet, it supports position detection; however, the legacy CS1-M and DS1-M switches used here are replaced by the CMSG, DMSG, and EMSG sensor families on the MBL.

Specifications follow the official AirTAC MAL datasheet (now discontinued). The MBL32X170SU 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 MBL32X170SU 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 MAL32X170SU Is Used
PCB Depaneling Router
Provides the 402 N push force at 0.5 MPa needed to plunge a router bit through FR4 fiberglass boards, utilizing the 170 mm stroke to clear the spindle during tool changes.
Connector Insertion Press
Drives a 12 mm rod with enough rigidity to seat multi-pin automotive connectors into housings, relying on the U flat-end cover for a rigid, non-articulating mount.
Pouch Diverter Gate
Actuates a sorting flap on a packaging line where the 170 mm stroke fully opens the lane, while the fixed rubber bumper absorbs the repetitive impact of the stroke end.
Replacing the Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X170SU with MBL32X170SU
To replace the MAL32X170SU, order the MBL32X170SU. Confirm your 32 mm bore, 170 mm stroke, G1/8 port, and the U flat-end back cover. The PT tapered thread form is standard. Since this SKU has the -S magnet, note that your older CS1-M or DS1-M reed switches will not fit the MBL; you must upgrade to the current CMSG, DMSG, or EMSG sensor series. If you need to manage heavier end-stop kinetic energy, step up to the 40 mm bore (628 N push at 0.5 MPa) or step down to the 25 mm bore (245 N push at 0.5 MPa) depending on your force requirements.
At 170 mm of travel, the 12 mm rod is susceptible to bending if subjected to off-center loads; use an external guide rail to prevent side-load damage. Remember that the fixed rubber bumper only absorbs shock and does not hold the load. If air pressure drops, the rod will drift, so install an external pilot-operated check valve if you need position holding.
Upgrade checklist
- ✓ Order the MBL32X170SU (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 MBL32X170SU instead of this discontinued model.
Airtac MAL32 Aluminum Alloy Mini Air Cylinder MAL32X170SU FAQ
Yes, the MAL32X170SU is discontinued. The exact drop-in replacement is the MBL32X170SU, which provides the same 32 mm bore, 170 mm stroke, G1/8 port, and U flat-end cover. Note that if you use the -S magnet for position sensing, the older CS1-M and DS1-M switches are replaced by the CMSG, DMSG, and EMSG sensor families on the MBL.
At 0.5 MPa operating pressure, the 32 mm bore generates 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
