About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X125SCA
The AirTAC MBL32X125SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a push force of 402 N at 0.5 MPa across its 125 mm stroke, making it well-suited for mid-range actuation tasks. The riveted rolling-packed barrel design keeps the overall footprint small and lightweight, though the crimped construction is not designed to be disassembled like a traditional tie-rod body.
This specific SKU includes a built-in magnet (-S) for use with AirTAC CMSG, DMSG, or EMSG sensor switches to track rod position. It also features a CA pivot back cover, allowing the cylinder to swing on a pin to accommodate arcing or angular loads. The piston utilizes a heterogeneous two-way seal that retains grease for long service life, while the carbon steel rod features 20 µm hard-chrome plating for high wear and corrosion resistance. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X125SCA Is Used
Textile Loom Guiding
Actuates a thread tensioning guide arm in compact textile looms, where the CA pivot absorbs angular rod movement and the 402 N force firmly holds the guide bracket.
Packaging Flap Folding
Pushes corrugated carton flaps during case erecting, using the 125 mm stroke to clear the packaging path and the built-in magnet to confirm flap closure for the sealing head.
Bottling Line Diverter
Drives a small swing gate to divert glass bottles on a conveyor, relying on the pivot back cover to handle the side sway as containers brush against the diverter arm.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X125SCA the Right Cylinder?
For applications needing less force, the Ø25 bore provides 245 N push at 0.5 MPa; for heavier loads, stepping up to the Ø40 bore yields 628 N. If your process requires adjustable end-cushioning to handle faster cycling or heavier masses, select the MBLC variant instead of this base MBL model. Because the CA pivot back cover is already specified, pair it with an SDB pivot bracket for secure angular mounting.
Keep in mind that a plain MBL does not hold its position or load if air pressure is lost or the valve is centered; the rod will drift or drop. The fixed rubber bumper only softens the end-of-stroke impact and is not a locking mechanism. To maintain a load without live pressure, an external rod lock or pilot-operated check valve is required. This unit uses a G1/8 port, a Ø12 mm rod, an M10x1.25 rod-end thread, and PT port threads.
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 MBL32X125SCA FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N push force and 346 N pull force. At 0.7 MPa, the push force is 563 N, with a theoretical maximum of 82 kgf at 1.0 MPa. It features a G1/8 port, a Ø12 mm rod, and an M10x1.25 rod-end thread.
The base MBL uses a fixed rubber bumper to soften the impact at the end of the stroke; it does not have an adjustable cushion screw. If your application requires adjustable air cushioning for heavier moving masses or higher speeds, you must step up to the MBLC variant.
