About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X300SCA
The AirTAC MBL32X300SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a push force of 402 N and a pull force of 346 N at 0.5 MPa, utilizing a 300 mm stroke to drive mechanisms that require extended reach without occupying a large footprint. The riveted rolling-packed barrel keeps the body light and compact, though it is not designed to be disassembled like a traditional tie-rod cylinder.
This specific SKU includes a CA pivot back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads during motion. It also features a built-in magnet (-S) for mounting AirTAC CMSG, DMSG, or EMSG sensor switches to detect rod position. The Ø12 mm carbon-steel piston rod is hardened with 20 µm chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X300SCA Is Used
PCB Conveyor Diverter
Uses the 402 N push force at 0.5 MPa to swing a diverter arm across a 300 mm span, routing populated PCB panels into testing stations.
Packaging Flap Folder
The CA pivot back cover absorbs angular stress while the 300 mm stroke tucks cardboard flaps closed on random-flow packaging lines.
Textile Beam Indexer
A DMSG electronic sensor tracks the rod position to confirm the 300 mm shift of a fabric beam between winding heads in a compact loom bay.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X300SCA the Right Cylinder?
If you need less force, step down to the 25 mm bore (245 N push at 0.5 MPa); if your application demands more power, step up to the 40 mm bore (628 N push at 0.5 MPa). Because this model has a 300 mm stroke, the unsupported Ø12 mm rod is highly susceptible to bending under side loads—use the CA pivot back cover with an SDB bracket to handle angular motion, add an external guide, or switch to an MBLD double-rod cylinder to prevent premature seal wear. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; choose the MBLC variant if you need adjustable air cushioning for heavier moving masses. Note that this cylinder cannot hold a load if air pressure is lost or the valve is centered—you must add an external rod lock or pilot-operated check valve for position holding. Replacement match: 32 mm bore, 300 mm stroke, G1/8 port, PT thread, CA back cover, magnet included.
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 MBL32X300SCA FAQ
At 0.5 MPa it provides 402 N push and 346 N pull; at 0.7 MPa the push force is 563 N, with a maximum theoretical force of 82 kgf at 1.0 MPa. The operating speed ranges from 30 to 800 mm/s.
It includes a built-in magnet (-S) for use with CMSG, DMSG, or EMSG sensor switches, but it does not have an adjustable cushion. The base MBL uses a fixed rubber bumper; you must switch to the MBLC variant for adjustable air cushioning.
