This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40SU — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40SU in place of this model. 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 MTAL40X40SU
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X40SU is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 40mm stroke, G1/4 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 drop-in replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40SU.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X40SU
The AirTAC MTAL40X40SU is a discontinued single-acting pull mini cylinder with a 40mm bore and 40mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. It delivers 439.4 N of usable pull force at 0.5 MPa. The exact drop-in replacement is the MTBL40X40SU.
This SKU features a U flat-end back cover, a G1/4 port, and an M12x1.25 rod-end thread. It includes a -S magnet for position sensing, compatible with CS1-M or DS1-M switches. The MTBL40X40SU upgrade retains these specs but uses a riveted rolling-packed body and CMSG, DMSG, or EMSG sensors. Both series use a fixed rubber bumper for end-of-stroke damping.

| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40SU |
| Bore size | Ø40 mm |
| Stroke | 40 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/4 |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.2 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40SU carries the same single-acting ratings.
Usable Pull Force (Ø40mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 439.4 N |
| 0.7 MPa | 650.4 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 MTAL40X40SU Is Used
Injection Mold Ejector
Pulls an injection mold core back during the 40mm stroke. The spring-extended fail-safe ensures the core stays retracted out of the mold cavity on air loss, preventing mold damage.
PCB Test Socket
Retracts a test probe head with 439.4 N pull at 0.5 MPa. The single-acting pull mechanism uses one 3/2 valve, simplifying pneumatic routing on dense test fixtures.
Gate Latch Withdrawal
Draws back a heavy machine guard latch. The U flat-end back cover provides rigid rear mounting, while the fixed rubber bumper absorbs the shock when the latch bottoms out.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X40SU with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40SU
To replace this MTAL40X40SU with the MTBL40X40SU, confirm the 40mm bore, 40mm stroke, G1/4 port, PT thread, U back cover, and the -S magnet. Remember the sensor family changes from CS1-M / DS1-M to CMSG / DMSG / EMSG. Operating pressure must be at least 0.2 MPa. The fail-safe home is extended, and you must apply no external load on the spring extend stroke.
If sizing force, this 40mm bore gives 439.4 N pull at 0.5 MPa. Stepping down to the 32mm bore drops the pull to 261.2 N at 0.5 MPa. Stepping up is not possible as 40mm is the largest MAL bore, but you can extend the stroke up to the 100mm standard maximum. For any stroke at or above 100mm, watch for side-load and rod-bending risks.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40SU (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X40SU instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X40SU FAQ
Yes, the MTAL40X40SU is discontinued. The exact drop-in replacement is the MTBL40X40SU, which matches the 40mm bore, 40mm stroke, G1/4 port, and U back cover. The MTBL uses a riveted rolling-packed body instead of threaded covers, and its -S magnet requires CMSG, DMSG, or EMSG sensors instead of the older CS1-M / DS1-M switches.
The usable pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. It is a single-acting pull cylinder where air retracts the rod and an internal spring extends it. The fail-safe home position is extended, meaning on air loss the spring pushes the rod back out. Minimum working pressure is 0.2 MPa.
