This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X50SCM, 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 MTAL20X50SCM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SCM is a single acting, pull (spring extend) aluminum-barrel mini cylinder with a Ø20mm bore and 50mm 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SCM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SCM
The AirTAC MTAL20X50SCM is a discontinued 20mm mini pneumatic cylinder. It is a single-acting pull type where air retracts the rod and an internal spring extends it. The fail-safe home is extended. It delivers a usable pull force of 81.7 N at 0.5 MPa. The direct replacement is the MTBL20X50SCM.
This SKU features a CM round-end back cover, a G1/8 port, and an M8 rod-end thread. It includes the -S magnet, which works with CS1-M and DS1-M switches. The MTAL uses threaded covers and a fixed rubber bumper. The MTBL replacement upgrades this to a riveted rolling-packed body and uses CMSG, DMSG, or EMSG sensors. Never apply external loads to the spring-extend stroke.

| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SCM |
| Bore size | Ø20 mm |
| Stroke | 50 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/8 |
| Rod thread | M8×1.25 |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SCM carries the same single-acting ratings.
Usable Pull Force (Ø20mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 81.7 N |
| 0.7 MPa | 134.4 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 MTAL20X50SCM Is Used
Electronic Connector Unlatching
Pulls a 50mm latch to release wire harness connectors, using 81.7 N at 0.5 MPa. The spring-extend fail-safe safely parks the latch open during power loss.
PCB Test Tray Draw-Back
Retracts a 50mm test tray on an SMT line. The single-acting pull mechanism and fixed rubber bumper absorb end-of-stroke shocks in tight enclosures.
Small Valve Tensioning
Applies pull tension to small pneumatic valve linkages. The M8 rod-end and CM round-end cover fit compact control panels without needing a double-acting line.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SCM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SCM
To replace the MTAL20X50SCM, use the direct replacement MTBL20X50SCM. Confirm the 20mm bore, 50mm stroke, G1/8 port, PT thread, CM back cover, and the -S magnet. Remember the sensor family changes from CS1-M/DS1-M to CMSG/DMSG/EMSG. This cylinder requires a minimum operating pressure of 0.2 MPa and parks extended on air loss.
For sizing, this 20mm bore gives 81.7 N pull at 0.5 MPa. Stepping up to the 25mm bore yields 137.2 N at 0.5 MPa. As the smallest standard size, 20mm has no smaller neighbor; choose 25mm if you need more force. For any stroke at or over 50mm, watch for rod-bending side loads.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SCM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50SCM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50SCM FAQ
Yes, the MTAL20X50SCM is discontinued. The direct replacement is the MTBL20X50SCM, which matches the 20mm bore, 50mm stroke, force, and port. The MTBL upgrades the body to a riveted rolling-packed design and uses CMSG, DMSG, or EMSG sensors instead of the older CS1-M/DS1-M switches.
It is a single-acting pull cylinder with a fixed rubber bumper. The usable pull force is 81.7 N at 0.5 MPa and 134.4 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 minimum of 0.2 MPa to retract the rod.
