Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL25X60CA
The AirTAC Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL25X60CA is a genuine single acting, pull (spring extend) aluminum-barrel mini round cylinder with a Ø25mm bore and 60mm stroke, G1/8 air ports and a fixed rubber bumper. Air drives the pull (work) stroke and the spring returns the rod — it rests extended on air loss.

About the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL25X60CA
The AirTAC MTBL25X60CA is a compact single-acting pull-type mini cylinder with a 25mm bore and 60mm stroke. Air retracts the 10mm rod to yield a usable pull force of 132.6 N at 0.5 MPa, while an internal spring extends it back out. The CA pivot clevis back cover allows the body to swing on a pin, accommodating arcing or angular loads without binding. Its riveted rolling-packed aluminum barrel keeps the assembly light for tight spaces, and the 20um hard-chrome plated carbon-steel rod resists scuffing during repetitive tensioning cycles.
This model lacks the -S magnet option, so it cannot take a CMSG reed or DMSG electronic sensor for position detection. Because it is single-acting, the overall length is A + 2 x stroke, making it physically longer than a double-acting MBL. The fixed rubber bumper absorbs end-of-stroke impact, as no adjustable air cushion is present in this spring-return design.

| Stroke | 60 mm |
| Acting type | Single acting, pull (spring extend) |
| Port size | G1/8 |
| Rod thread | M10×1.25 |
| 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. Thread options: PT / G / NPT.
Usable Pull Force (Ø25mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 132.6 N |
| 0.7 MPa | 215.0 N |
These are the usable single-acting forces after the return spring — lower than a same-bore double-acting MBL. Size with a margin.

Where the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL25X60CA Is Used
Packaging Flap Sealing
Draws a packaging flap closed on a carton sealer using its 132.6 N pull force, with the CA clevis allowing the cylinder to swing slightly as the cardboard thickness varies.
Textile Beam Tensioning
Pulls a textile warp beam tensioner into position during a 60mm stroke, relying on the spring-extend fail-safe to release tension and rest open if the 0.2 MPa air supply drops.
Stamping Die Ejector
Retracts a small stamping die holding pin against a 25mm bore pull force, letting the internal spring push the pin out to eject a blank part when air is vented.
Is the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL25X60CA the Right Cylinder?
Choose this 25mm bore when an application needs exactly 132.6 N of pull force at 0.5 MPa. If your load is lighter, step down to the 20mm bore, which provides 84.8 N at 0.5 MPa; if you need more force, step up to the 32mm bore, which offers 224.8 N at 0.5 MPa. Unlike the MSBL push type that fails safe retracted, this MTBL spring-extends to a defined extended home on air loss, suiting mechanisms that must rest open. A minimum of 0.2 MPa operating pressure is required to overcome the return spring, and no external load should be applied during the unpowered extend stroke. For a direct replacement, match the 25mm bore, 60mm stroke, G1/8 port, default PT thread, CA pivot back cover, and confirm no magnet is needed.
Quick checklist
- ✓ Usable pull force at your pressure (min 0.2 MPa)
- ✓ Fail-safe rest position (extended)
- ✓ No external load on the spring return stroke
- ✓ Magnet (S) for sensors?
- ✓ Side load — consider a guided cylinder
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 Use the correct mounting accessory (LB / FA / SDB) and back cover (CA / U).
- check Installation by qualified personnel per AirTAC docs.
Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL25X60CA FAQ
The 25mm bore yields a usable pull force (net of the return spring) of 132.6 N at 0.5 MPa and 215 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the spring and retract the rod, with a maximum operating pressure of 1.0 MPa.
No, this specific SKU lacks the -S built-in magnet, so it cannot accept AirTAC CMSG, DMSG, or EMSG sensor switches. Additionally, because it is a single-acting pull cylinder, the fixed rubber bumper means there is no adjustable air cushion, and the spring will extend the rod to its fail-safe home on air loss.
