About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X5U
The AirTAC MBL32X5U is a compact double-acting aluminum mini round cylinder engineered for extremely tight spaces where a standard 10mm stroke would bottom out. Delivering a push force of 402 N at 0.5 MPa, this 32mm bore unit uses a 5mm stroke for high-impact micro-clamping. The riveted rolling-packed barrel crimps the covers directly to the tube, creating a lightweight, permanently sealed body that is not designed for field disassembly like a tie-rod cylinder.
This specific SKU features a U flat-end back cover for rigid fixed mounting and a default PT tapered port thread. Because it lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. The piston relies on a heterogeneous two-way seal that retains grease for long service life, while the carbon steel rod features 20 um hard-chrome plating to resist wear and corrosion in demanding environments.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X5U Is Used
PCB Edge Clamping
Provides 402 N of holding force to secure delicate printed circuit boards during automated wave soldering without flexing the panel.
Connector Insertion Press
Uses the precise 5mm stroke to drive IC sockets into housings on semiconductor assembly lines, preventing over-travel damage.
Carton Flap Tucking
Executes rapid 5mm tucks on small pharmaceutical carton flaps prior to glue application, fitting neatly within narrow machine guards.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X5U the Right Cylinder?
When sizing this 32mm bore model, stepping down to the 25mm bore reduces your push force to 245 N at 0.5 MPa, while stepping up to the 40mm bore increases it to 628 N. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; if your micro-clamp requires adjustable air cushioning to slow heavier moving masses, upgrade to the MBLC variant. Note that a plain MBL does not hold its position if air pressure is lost or the valve is centered, as the rod will drift. To replace this unit exactly, match the 32mm bore, 5mm stroke, G1/8 port, PT thread, U flat-end back cover, and no magnet.
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 MBL32X5U 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 maximum theoretical force is 82 kgf at 1.0 MPa. The double-acting operating speed ranges from 30-800 mm/s.
No. Because this SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper, not an adjustable cushion screw; you must step up to the MBLC variant for adjustable air cushioning.
