This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X15U — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X15U 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 MTAL40X15U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X15U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 15mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X15U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X15U
The AirTAC MTAL40X15U is a discontinued single-acting pull-type mini cylinder with a 40mm bore and 15mm stroke. Air retracts the rod while an internal spring extends it, yielding a fail-safe extended home position. It delivers a usable pull force of 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. The exact drop-in replacement is the MTBL40X15U, matching the G1/4 port, M12x1.25 rod thread, and U back cover.
This MTAL40X15U features a fixed rubber bumper and threaded covers, whereas the MTBL40X15U upgrade uses a riveted rolling-packed body. This specific SKU lacks a magnet, so it cannot take a position sensor; the -S MTAL used CS1-M/DS1-M switches, while the MTBL uses CMSG/DMSG/EMSG. Never apply external load on the spring extend stroke.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X15U Technical Specifications

| Bore size | Ø40 mm |
| Stroke | 15 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X15U 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 MTAL40X15U Is Used
Press Brake Clamp Pullback
Retracts a upper clamp on a press brake to release sheet metal. The 439.4 N pull at 0.5 MPa securely overcomes the die spring, while the fail-safe extended position holds the clamp open during air loss.
Injection Mold Ejector Lock
Pulls a mechanical lock pin on an injection molding plate. The short 15mm stroke and 650.4 N pull at 0.7 MPa provide rapid retraction, and the spring-extended fail-safe keeps the mold safely locked.
Packaging Lid Tensioner
Draws back a tension arm on a carton sealing machine to maintain constant belt tension. The spring-extend function automatically releases tension when the 3/2 valve is de-energized.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X15U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X15U
To replace the MTAL40X15U, use the MTBL40X15U drop-in. Confirm the 40mm bore, 15mm stroke, G1/4 port, PT thread, U flat-end back cover, and non-magnetic setup. Remember the 0.2 MPa minimum working pressure and that the fail-safe home is extended. If you need less force, step down to the 32mm bore (261.2 N pull at 0.5 MPa). As 40mm is the largest MTAL size, you cannot step up within the series. The 15mm stroke is short, keeping rod bending stress low, but always avoid side loads. The fixed rubber bumper absorbs impact; for adjustable cushioning, consider the current MBLC line.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X15U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X15U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X15U FAQ
Yes, the MTAL40X15U is discontinued. The exact drop-in replacement is the MTBL40X15U, which matches the 40mm bore, 15mm stroke, G1/4 port, and U back cover. The MTBL upgrade features a riveted rolling-packed body instead of threaded covers.
The MTAL40X15U is single-acting pull, spring extend. The usable pull force is 439.4 N at 0.5 MPa and 650.4 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (minimum 0.2 MPa to overcome the internal spring). The fail-safe home is extended. This non-magnetic SKU cannot take a sensor.
