About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X350U
The AirTAC MBL32X350U is a double-acting aluminum mini round cylinder engineered for compact machines requiring a long 350mm reach. Operating at 0.5 MPa, it generates 402N of push force and 346N of pull force, making it a solid choice for mid-range actuation. Its defining characteristic is a small footprint paired with a lengthy stroke, fitting into tight assemblies where a standard profile body would be too bulky. The rigid U flat-end rear cover provides a stable fixed mounting base for straightforward inline installations.
Because this specific SKU lacks the -S magnet suffix, it cannot accommodate a position sensor. The body relies on a riveted rolling-packed construction where the covers are crimped to the barrel, rendering it a lightweight, non-rebuildable unit unlike traditional tie-rod cylinders. Impact absorption at the stroke ends is handled by a fixed rubber bumper rather than an adjustable cushion screw. Inside, a heterogeneous two-way piston seal retains lubricant, and the carbon-steel rod features 20um hard-chrome plating to resist wear and corrosion over its long travel.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X350U Is Used
PCB Conveyor Routing
Drives a routing blade across a 350mm printed circuit board conveyor lane, utilizing the 402N push force to cleanly sever connection tabs in confined electronics assembly lines.
Packaging Lane Diverter
Extends a deflector arm over a 350mm packaging width, using the 346N pull force to retract the gate rapidly and sort small cartons at speeds up to 800mm/s.
Textile Bobbin Loader
Pushes empty yarn bobbins into a spinning lathe chuck, where the compact riveted aluminum body fits neatly between the machine's frame rails without requiring ISO 15552 clearance.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X350U the Right Cylinder?
When sizing this 32mm bore model, stepping down to the 25mm bore yields 245N of push force at 0.5 MPa, while stepping up to the 40mm bore provides 628N. If your cycle speeds generate destructive end-impact forces on the rubber bumper, upgrade to the MBLC variant for adjustable air cushioning. For applications needing push or pull only, the MSBL and MTBL single-acting versions are available in this size range.
With a 350mm stroke on a Ø12mm rod, side-load tolerance is minimal; long unsupported mini rods are prone to bending under lateral stress. Implement an external guide rail, switch to a CA pivot back cover for arcing loads, or use an MBLD double-rod cylinder to prevent rod bearing damage. Note that the fixed rubber bumper softens end-of-stroke impacts but does not lock the rod; if pressure is lost, the load will drift or drop, requiring an external pilot-operated check valve for position holding. This SKU uses a G1/8 port with PT thread form and cannot accept a CMSG or DMSG sensor switch.
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 MBL32X350U FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N push and 346N pull force. At 0.7 MPa, the push force increases to 563N, with a theoretical maximum of 82kgf at 1.0 MPa. The operational speed range is 30-800mm/s.
No, this specific SKU lacks the -S magnet, so CMSG, DMSG, or EMSG position switches cannot be fitted. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke damping; for adjustable air cushioning, you must specify the MBLC variant.
