About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X125-CA
The AirTAC MBL32X125-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 402 N push force at 0.5 MPa across its 125 mm stroke, making it well-suited for mid-range actuation tasks. The riveted rolling-packed aluminum barrel keeps the overall footprint and weight exceptionally low, though the crimped construction means it is not designed to be disassembled like a traditional tie-rod body.
This specific SKU features a CA pivot (clevis) back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the Ø12 mm carbon-steel piston rod is protected by a 20 µm hard-chrome plating to resist wear and corrosion. Because this configuration lacks the -S suffix for a built-in magnet, it cannot support a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X125-CA Is Used
PCB Router Z-Axis Gate
Actuates a safety cover on a printed circuit board routing machine, where the 402 N push force at 0.5 MPa easily overcomes the gate's spring tension.
Carton Flap Folder
Pivots a folding arm on a packaging line to tuck minor flaps before carton sealing, utilizing the CA clevis to accommodate the arm's arc.
Connector Pick-and-Place
Drives a small vertical gripper assembly in an electronics assembly handler, where the 125 mm stroke provides the reach needed to clear tall component feeders.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X125-CA the Right Cylinder?
This 32 mm bore provides 402 N of push force at 0.5 MPa. If your application requires less force, the 25 mm bore offers 245 N of push force; if you need to move heavier payloads, stepping up to the 40 mm bore yields 628 N. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts, so for faster cycling or heavier moving masses, consider the MBLC variant which features an adjustable air cushion. Keep in mind that a plain double-acting cylinder like this does not hold its load if air pressure is lost or the valve is centered—the rod will drift, requiring an external rod lock or pilot-operated check valve for fail-safe positioning.
With a 125 mm stroke, the unsupported Ø12 mm rod has an increased vulnerability to side-load bending. For this length, it is highly recommended to use an external guide mechanism to prevent rod-bearing wear. The CA pivot back cover on this unit helps safely absorb minor angular misalignments. When ordering a replacement, match the 32 mm bore, 125 mm stroke, G1/8 port, default PT thread form, CA back cover, and the lack of a magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ 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 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBL Aluminum Alloy Mini Cylinder MBL32X125-CA FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa, which is the upper limit of its 0.15-1.0 MPa operating pressure range.
No, the base MBL uses a fixed rubber bumper that cannot be adjusted; if you need adjustable air cushioning, you must specify the MBLC variant. Additionally, because this specific SKU lacks the -S suffix for a built-in magnet, it cannot accept a CMSG, DMSG, or EMSG electronic or reed position sensor switch.
