This model is discontinued
AirTAC has phased out the MTAL series. You can still order this code here: we ship the direct replacement MTBL20X50CM, 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 MTAL20X50CM
The AirTAC Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50CM 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CM.

About the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50CM
The AirTAC MTAL20X50CM is a discontinued single-acting pull mini cylinder. Air retracts the rod, while an internal spring extends it. Fail-safe home is extended. It delivers 81.7 N usable pull at 0.5 MPa. The direct replacement is the MTBL20X50CM.
This 20mm bore unit uses a G1/8 port and M8x1.25 rod thread. It has a CM round-end back cover. Lacking the -S magnet, this SKU cannot take a position sensor. The MTBL upgrade switches from threaded covers to a riveted rolling-packed body.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50CM Technical Specifications
| Model | Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50CM |
|---|---|
| Series | MAL single-acting mini cylinder (discontinued) |
| Replacement | AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CM |
| 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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CM 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 MTAL20X50CM Is Used
Electronic Connector Unlatch
Pulls a latch back 50mm to release an electronic connector block, using 81.7 N at 0.5 MPa, with the spring safely pushing the latch closed on air loss.
PCB Test Socket Retract
Draws a test probe plate away from a PCB using 134.4 N at 0.7 MPa, ensuring the spring-extend fail-safe re-engages the board safely.
Light Wire Tensioner
Tensions fine copper wire during a winding process; the 8mm hard-chrome rod provides smooth single-direction pull without mid-stroke locking.
Replacing the Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50CM with AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CM
Replace this MTAL20X50CM with the MTBL20X50CM. Confirm the 20mm bore, 50mm stroke, G1/8 port, and CM cover match your jig. Since this SKU lacks the -S magnet, it cannot hold a sensor; if you need position detection, step up to an MTBL20X50SCM and use CMSG/DMSG/EMSG switches instead of the legacy CS1-M/DS1-M. Minimum operating pressure is 0.2 MPa. Never apply external load on the spring extend stroke.
To size either way: stepping down is not an option as 20mm is the smallest bore. Stepping up to the 32mm bore yields 261.2 N pull at 0.5 MPa if you need more force. The fixed rubber bumper absorbs end-of-stroke shock.
Upgrade checklist
- ✓ Order the AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CM (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 AIRTACMTBLREARSINGLEACTINGMINICYLINDERMTBL20X50CM instead of this discontinued model.
Airtac MTAL Rear Single Acting Mini Cylinder MTAL20X50CM FAQ
Yes, the MTAL20X50CM is discontinued. The direct replacement is the MTBL20X50CM, matching the 20mm bore, 50mm stroke, G1/8 port, and CM cover. The MTBL upgrades the body to a riveted rolling-packed design.
It is a single-acting pull cylinder. 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 spring pushes the rod out upon air loss. Minimum pressure is 0.2 MPa.
