This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL32X40SU, with the same bore, stroke, output force, port and mounting, so it fits the same application. The replacement upgrades to a riveted rolling-packed body and CMSG / DMSG / EMSG sensors (the MAL used CS1-M / DS1-M).
Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X40SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X40SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø32mm bore and 40mm stroke, G1/8 ports and a fixed rubber bumper. Air drives the pull (work) stroke and the spring returns the rod — it rests extended on air loss. This model is discontinued; the direct replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X40SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X40SU
The AirTAC MTAL32X40SU is a discontinued single-acting pull-type mini cylinder. Air retracts the 12mm rod to do the work, while an internal spring extends it back out when air is released. The fail-safe home position is extended. It delivers a usable pull force of 261.2 N at 0.5 MPa. The direct replacement is the MTBL32X40SU, matching the 32mm bore, 40mm stroke, G1/8 port, and U back cover.
This -S variant includes a magnet for CS1-M or DS1-M reed switches; the MTBL upgrade uses CMSG/DMSG/EMSG sensors. The MTAL features threaded covers, whereas the MTBL uses a riveted rolling-packed body. A fixed rubber bumper absorbs end-of-stroke impact. Apply no external load on the spring extend stroke to avoid bending the rod.

| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Fixed rubber bumper |
| Max standard stroke | Up to 100 mm |
Single-acting minimum working pressure is 0.2 MPa (the air must overcome the return spring). Do not apply an external load during the spring return stroke. The AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X40SU carries the same single-acting ratings.
Usable Pull Force (Ø32mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 261.2 N |
| 0.7 MPa | 399.4 N |
Usable single-acting force after the return spring — lower than a same-bore double-acting cylinder. Size with a margin.

Where the Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X40SU Is Used
Injection Mold Ejector
Pulls an ejector pin back inside the mold cavity during plastic injection. The 261.2 N pull at 0.5 MPa retracts the mechanism, while the spring-extend fail-safe pushes the pin out safely if plant air drops.
Packaging Lid Latch
Draws back a mechanical latch to release filled carton lids on a packaging line. The single-acting pull action uses one air line, and the U flat-end back cover mounts rigidly to the machine frame.
Textile Tension Arm
Retracts a tensioning arm to take up slack in textile webs. The 40mm stroke provides precise material control, and the fixed rubber bumper softens the high-speed 50-800 mm/s retraction impact.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X40SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X40SU
To replace this MTAL32X40SU, order the MTBL32X40SU. Confirm the 32mm bore, 40mm stroke, G1/8 PT port, M10x1.25 rod thread, U flat-end back cover, and magnet. The MTBL uses CMSG/DMSG/EMSG switches instead of the older CS1-M/DS1-M. Both require a 3/2 valve and a 0.2 MPa minimum pressure. The fail-safe home is extended, and you must apply no external load on the spring extend stroke.
If sizing, step down to the 25mm bore for 137.2 N at 0.5 MPa, or step up to the 40mm bore for 439.4 N at 0.5 MPa. This 40mm stroke is well under the 100mm max, keeping rod-bending risk low.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X40SU (same bore/stroke/force)
- ✓ Same pull direction and extended fail-safe home
- ✓ Min 0.2 MPa; no external load on the spring return
- ✓ Sensor: swap CS1-M/DS1-M → CMSG/DMSG/EMSG
- ✓ 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 0.2 – 1.0 MPa (min 0.2 to overcome the spring).
- check Apply no external load on the spring return stroke.
- check Avoid side load on the piston rod.
- check Front/rear covers are threaded — not for field disassembly.
- check For new builds, specify the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL32X40SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL32X40SU FAQ
Yes, the MTAL32X40SU is discontinued. The direct replacement is the MTBL32X40SU, which matches the 32mm bore, 40mm stroke, G1/8 port, and U back cover. The MTBL uses a riveted body instead of threaded covers, and you must switch from CS1-M/DS1-M switches to CMSG/DMSG/EMSG sensors.
The usable pull force is 261.2 N at 0.5 MPa and 399.4 N at 0.7 MPa. It is single-acting pull, meaning air retracts the rod and a spring extends it. The fail-safe home position is extended. It requires a 0.2 MPa minimum pressure, and you must not apply external load on the spring extend stroke.
