About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X450U
The AirTAC MBLC32X450U is a double-acting aluminum mini cylinder with a 32mm bore and 450mm stroke, delivering 402N push and 346N pull at 0.5 MPa. Its riveted rolling-packed barrel keeps the body compact for tight spaces, while the heterogeneous two-way grease-retaining piston seal maintains lubrication over long travel distances. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot accept CMSG, DMSG, or EMSG position sensors.
The defining feature is the screw-adjustable pneumatic air cushion at both ends. On a 450mm move, the piston builds significant momentum; tuning the cushion needles decelerates the rod smoothly near the end caps, absorbing energy that a fixed rubber bumper cannot handle. The Ø12mm carbon-steel rod features 20µm hard-chrome plating to resist wear, though its small diameter means side-load tolerance is low.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X450U Is Used
Textile Beam Loom
Shifts warp tensioner levers across a 450mm span; the tuned air cushion prevents sudden jerks that would snap delicate yarn during high-speed weaving.
PCB Unloader Shuttle
Transfers populated boards out of an SMT line; the 402N force drives the carriage while the cushion ensures boards do not slide forward on sudden stops.
Warehouse Tray Pusher
Ejects nested plastic storage trays from a vertical magazine, relying on the 450mm travel to reach deep slots without impacting the frame.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X450U the Right Cylinder?
This 32mm bore gives 402N push at 0.5 MPa. If you need less force, step down to the 25mm bore (245N push); if moving heavier masses, step up to the 40mm bore (628N push). Choose this MBLC version over the base MBL when running fast or high-frequency cycles, as the tunable cushion protects the end covers from impact damage that a fixed bumper would suffer.
At 450mm of stroke, the small Ø12mm rod is highly susceptible to bending under side loads. To prevent premature seal failure and rod damage, guide the load externally, use a CA or SDB pivot mounting to accommodate arcing loads, or switch to an MBLD double-rod cylinder. The U flat-end back cover provides rigid axial mounting, and the standard PT tapered port thread matches the G1/8 porting. Note that the air cushion only decelerates near the stroke ends; it does not hold position if air pressure is lost.
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 MBLC Aluminum Alloy Mini Air Cylinder MBLC32X450U FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N push and 346N pull force. At 0.7 MPa, it delivers 563N push and 484N pull. The maximum theoretical force is 82 kgf at 1.0 MPa.
A screw needle valve at each end lets you tune the exhaust flow restriction. As the piston enters the cushion zone near the stroke end, trapped air compresses and decelerates the rod smoothly. This is essential on long 450mm strokes to prevent end-cover damage, unlike the base MBL which relies on a fixed rubber bumper.
