Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X50CA
The AirTAC Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X50CA is a genuine single acting, pull (spring extend) aluminum-barrel mini round cylinder with a Ø32mm bore and 50mm 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 MTBL32X50CA
The AirTAC MTBL32X50CA is a compact single-acting pull-type mini cylinder where air retracts the rod and an internal spring extends it. Designed for a 32 mm bore and 50 mm stroke, it delivers a usable pull force of 224.8 N at 0.5 MPa. This makes it well-suited for drawing mechanisms closed or tensioning components within a 50 mm travel range.
This SKU features a CA pivot clevis back cover that swings on a pin to absorb arcing or angular loads. It uses a G1/8 port, a 12 mm hard-chrome carbon-steel rod, and a riveted rolling-packed aluminum barrel. Because this specific configuration lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position sensors. A fixed rubber bumper absorbs end-of-stroke impact, as no adjustable air cushion is present.

| 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 MTBL32X50CA Is Used
Packaging Flap Sealing
Draws carton flaps closed with 224.8 N of pulling force at 0.5 MPa, utilizing the 50 mm stroke to tension the mechanism securely before the fail-safe spring extends to release the box.
Textile Loom Tensioning
Uses the CA pivot clevis to articulate with a swinging guide arm, pulling the thread guide back into its home position while accommodating the angular arc of the weaving mechanism.
Vacuum Door Latching
Retracts a 12 mm rod to pull a chamber door tightly shut against its seal, relying on the internal spring to push the latch open and safely vent the chamber if compressed air drops.
Is the Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL32X50CA the Right Cylinder?
Select this 32 mm bore when you need 224.8 N of pull force at 0.5 MPa to handle the workload on the retraction stroke. If your pulling task is lighter, step down to the 25 mm bore, which provides 132.6 N at 0.5 MPa. For heavier pulling or seating demands, step up to the 40 mm bore, offering 339.1 N at 0.5 MPa. Remember that the return spring opposes the air stroke, so usable force is lower than a double-acting MBL.
Choose the MTBL pull type if your mechanism requires a fail-safe extended home position upon air loss, whereas the MSBL push type fails safe retracted. This CA pivot mount is ideal for articulating linkages that arc during travel. A minimum operating pressure of 0.2 MPa is required to overcome the spring, and you must apply no external load during the spring-extend return stroke. When replacing, match the 32 mm bore, 50 mm stroke, G1/8 port, PT thread, CA pivot cover, and confirm no magnet is fitted.
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 MTBL32X50CA FAQ
The usable pull force is 224.8 N at 0.5 MPa and 363 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring, and operates safely up to 1.0 MPa.
No, this specific SKU does not have the -S built-in magnet, so it cannot support CMSG, DMSG, or EMSG position switches. Additionally, it relies on a fixed rubber bumper rather than an adjustable air cushion, and the spring drives the rod to an extended fail-safe home on air loss.
