About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X300U
The AirTAC MBL32X300U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it provides 402 N of push force and 346 N of pull force across its 300 mm stroke. The U flat-end back cover provides a rigid rear mounting face for straightforward fixed attachment. This genuine AirTAC unit uses a G1/8 port and a Ø12 mm carbon steel rod with 20 um hard-chrome plating for wear resistance.
Unlike tie-rod bodies, the MBL features a riveted rolling-packed aluminum barrel where the covers are crimped to the tube, making it exceptionally light but not designed for field disassembly. It relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion. Because this specific SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X300U Is Used
PCB Conveyor Gate
Lifts a hinged conveyor section in an electronics assembly line, using its 300 mm stroke to create a maintenance pass-through while providing 402 N of push force at 0.5 MPa.
Carton Pusher Diverter
Pushes small packaged goods from a main roller track onto a secondary packing belt, where the rigid U flat-end mount withstands repetitive axial cycling.
Textile Yarn Guide
Shifts a yarn guide carriage across a knitting machine width, relying on the lightweight riveted aluminum barrel to minimize moving mass on the carriage frame.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X300U the Right Cylinder?
This 32 mm bore bridges the gap between the lighter 25 mm bore (245 N push at 0.5 MPa) and the heavier 40 mm bore (628 N push at 0.5 MPa). If your application requires adjustable end-cushioning to absorb heavier kinetic energy, step up to the MBLC variant; for single-acting push or pull needs, consider the MSBL or MTBL models. The fixed rubber bumper softens impact but does not lock the rod—unpressurized loads will drift, requiring an external pilot-operated check valve for position holding.
With a 300 mm stroke on a Ø12 mm rod, side-load tolerance is low; the unsupported rod is prone to bending under lateral forces. To manage this, use an external guide rail, pair the cylinder with a pivot bracket, or switch to the MBLD double-rod anti-rotation type. This SKU uses a default PT tapered port thread and a U flat-end back cover.
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 MBL32X300U FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force increases to 563 N. The theoretical maximum force is 82 kgf at 1.0 MPa. The operational speed ranges from 30-800 mm/s.
No. Because this SKU lacks the -S suffix, it cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper to absorb end-of-stroke impacts; for adjustable air cushioning, you must specify the MBLC variant.
