Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X15CA
The AirTAC Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X15CA is a genuine single acting, pull (spring extend) aluminum-barrel mini round cylinder with a Ø32mm bore and 15mm 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 MTBL32X15CA
The AirTAC MTBL32X15CA is a compact single-acting pull-type cylinder where air retracts the rod and an internal spring extends it. This 32mm bore generates 224.8 N of usable pull force at 0.5 MPa, suited to short 15mm tensioning or seating tasks. Its fail-safe design drives the rod to an extended home position upon air loss, requiring only a simple 3/2 valve for control.
This SKU features a CA pivot clevis back cover that swings on a pin to absorb arcing or angular loads, preventing side-load binding. The riveted aluminum barrel and 20 um hard-chrome plated carbon-steel rod operate at 50-800 mm/s with a fixed rubber bumper. Lacking the -S magnet code, this specific unit cannot host CMSG or DMSG position sensors.
Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X15CA Technical Specifications
| Model | Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X15CA |
|---|---|
| Series | MBL aluminum-barrel mini round cylinder |
| Bore size | Ø32 mm |
| Stroke | 15 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 (Ø32mm)
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 224.8 N |
| 0.7 MPa | 363.0 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 MTBL32X15CA Is Used
Packaging Flap Sealing
Draws a carton flap closed with 224.8 N of pull force at 0.5 MPa, using the 15mm stroke to tension the mechanism securely before the spring extends it open during an air-loss stop.
PCB Test Socket Tensioning
Pulls a test fixture lid down onto a printed circuit board, where the CA pivot clevis accommodates slight misalignment and the fail-safe extended home releases the board safely.
Textile Loom Tension Arm
Retracts a yarn tensioning arm on a short 15mm stroke; the spring-extend design ensures the arm lifts away from the fabric to a defined safe rest position when the loom halts.
Is the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X15CA the Right Cylinder?
Select this 32mm bore for short-stroke pulling requiring 224.8 N at 0.5 MPa. To step down, the 25mm bore offers 132.6 N at 0.5 MPa; to step up, the 40mm bore provides 339.1 N at 0.5 MPa. Unlike the MSBL push type that fails safe retracted, this MTBL spring-extend variant ensures a defined extended rest state on air loss. It requires a minimum 0.2 MPa to overcome the return spring.
The CA clevis is ideal for mechanisms with angular rod movement. Remember that the fixed rubber bumper is not a lock, and the spring-extend return stroke must remain free of external loads. For replacements, match the 32mm bore, 15mm stroke, G1/8 port, PT thread, CA pivot cover, and confirm no magnet is required.
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 MTBL32X15CA FAQ
The usable pull force, already net of the return spring, is 17.6 N at 0.2 MPa, 155.7 N at 0.4 MPa, 224.8 N at 0.5 MPa, and 363 N at 0.7 MPa. The operating pressure range is 0.2-1.0 MPa, requiring at least 0.2 MPa to overcome the internal spring.
No. This MTBL32X15CA SKU lacks the -S code for a built-in magnet, so it cannot support AirTAC CMSG reed or DMSG electronic sensors. You would need the MTBL32X15SCA variant to mount a sensor switch for detecting rod position.
