This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL40X100U, 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 MTAL40X100U
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X100U is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø40mm bore and 100mm 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 direct replacement is the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X100U.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X100U
The AirTAC MTAL40X100U is a discontinued 40mm single-acting pull-type mini cylinder. Air retracts the rod while an internal spring extends it. It delivers 439.4N of usable pull at 0.5MPa. The direct replacement is the MTBL40X100U.
This SKU features a U flat-end back cover and a PT port thread form. It has no magnet (-S) and cannot take a position sensor. The MTAL uses threaded covers and fixed rubber bumpers; the MTBL upgrade uses a riveted rolling-packed body.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X100U Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X100U |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X100U |
| Bore size | Ø40 mm |
| Stroke | 100 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X100U 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 MTAL40X100U Is Used
Injection Mold Ejector Retract
Pulls an injection mold ejector pin clear of the cavity using 439.4N at 0.5MPa. The spring-extended fail-safe parks the pin out of the mold during air loss.
Packaging Machine Flap
Draws back a cardboard packaging machine flap. The single-acting pull mechanism requires only one 3/2 valve to manage the retraction cycle.
Welding Fixture Clamp
Releases a robotic welding fixture clamp. The fixed rubber bumper absorbs the 100mm stroke impact without needing adjustable cushioning.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X100U with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X100U
Replace the MTAL40X100U with the MTBL40X100U. Confirm the 40mm bore, 100mm stroke, G1/4 port, M12x1.25 rod-end thread, and U flat-end back cover. The MTBL lacks a magnet, matching this no-S SKU. Minimum working pressure is 0.2MPa. On air loss, the spring extends the rod (fail-safe extended), so apply no external load on the extend stroke.
To size up or down: the next size down is the 32mm bore (261.2N pull at 0.5MPa). The 40mm bore is the largest standard size. For this 100mm max standard stroke, mind side-load and rod-bending forces.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X100U (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL40X100U instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL40X100U FAQ
Yes, the MTAL40X100U is discontinued. The direct replacement is the MTBL40X100U, which matches the 40mm bore, 100mm stroke, G1/4 port, and U flat-end cover.
The usable pull force is 439.4N at 0.5MPa and 650.4N at 0.7MPa (66.3 kgf max). The minimum working pressure is 0.2MPa. Because this SKU has no magnet, it cannot take a CS1-M or DS1-M sensor; the MTBL upgrade uses CMSG/DMSG/EMSG switches.
