This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CM — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CM 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 MTAL40X20CM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20CM is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 20mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20CM
The AirTAC MTAL40X20CM is a discontinued 40mm bore, 20mm stroke single-acting pull mini cylinder. Air retracts the rod for the work stroke, while an internal spring extends it. It delivers a usable pull force of 439.4 N at 0.5 MPa and parks extended on air loss. The exact drop-in replacement is the MTBL40X20CM, matching the G1/4 port, M12x1.25 rod thread, and CM round-end back cover.
This MTAL40X20CM unit has no magnet (-S) and cannot take a position sensor. It features fixed rubber bumpers and threaded covers, whereas the MTBL replacement uses a riveted rolling-packed body. Apply no external load on the spring extend stroke to avoid damage. The PT tapered port handles the 16mm hard-chrome rod.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20CM Technical Specifications

| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CM |
| Bore size | Ø40 mm |
| Stroke | 20 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CM 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 MTAL40X20CM Is Used
Injection Mold Ejection
Pulls a mold ejector pin back against 439.4 N at 0.5 MPa during press operation, relying on the spring to safely extend the pin out of the way on air loss.
Packaging Flap Latch
Retracts a mechanical latch to release carton flaps on a packaging line, using the 16mm rod and 20mm short stroke for compact machine integration.
Press Brake Tension
Draws back a sheet metal tension clamp in a press brake, benefiting from the CM round-end cover for tight mounting and the fixed bumper for shock absorption.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20CM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CM
To replace this MTAL40X20CM, order the MTBL40X20CM. Confirm the 40mm bore, 20mm stroke, G1/4 port, PT thread, and CM round-end cover all match. Because this SKU lacks the -S magnet, it cannot accept CS1-M/DS1-M sensors, and the MTBL upgrade would require CMSG/DMSG/EMSG switches if sensing is added later. Maintain a 0.2 MPa minimum working pressure and never apply external load on the spring extend stroke, as the fail-safe home is extended.
For sizing flexibility, stepping down to the 32mm bore yields 261.2 N pull at 0.5 MPa, while stepping up is not available as 40mm is the largest standard MAL bore. At 20mm stroke, side-load and rod-bending risks are minimal, but ensure rigid front-cover guide alignment. The fixed rubber bumper absorbs end-of-stroke impact without adjustment.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X20CM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X20CM FAQ
Yes, the MTAL40X20CM is discontinued. The exact drop-in replacement is the MTBL40X20CM, matching the 40mm bore, 20mm stroke, G1/4 port, and CM cover. The MTBL upgrades the threaded covers to a riveted rolling-packed body.
The single-acting pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. The fail-safe home is EXTENDED, meaning the internal spring pushes the rod out on air loss. It requires a 0.2 MPa minimum pressure to retract the rod.
