About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X75U
The AirTAC MBL32X75U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It provides 402 N of push force and 346 N of pull force at 0.5 MPa, making this 32 mm bore, 75 mm stroke size ideal for mid-range actuation tasks. The U suffix indicates a rigid flat-end back cover, providing a solid fixed mounting point where rear pivot movement is not required.
Unlike tie-rod cylinders that can be rebuilt, this unit uses a riveted rolling-packed aluminum barrel that crimps the covers to the tube for a lighter, smaller footprint. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the Ø12 mm carbon-steel piston rod features 20 μm hard-chrome plating for wear and corrosion resistance. Because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot support CMSG, DMSG, or EMSG position sensing.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X75U Is Used
PCB Router Gating
Actuates a pneumatic gate on a PCB routing machine, using its 402 N push force at 0.5 MPa to divert panels into inspection lanes within a compact 75 mm stroke envelope.
Carton Flap Folding
Drives a small folding arm on a packaging line, relying on the 346 N pull force to tuck cardboard flaps before tape sealing in a tight conveyor transfer zone.
Connector Insertion Press
Provides the linear motion to seat electronic pin connectors into housings, utilizing the rigid U flat-end cover to maintain alignment without rear pivot deflection.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X75U the Right Cylinder?
At 0.5 MPa, this 32 mm bore yields 402 N of push force. If your assembly requires less force, stepping down to the 25 mm bore drops the output to 245 N; if you need to move heavier jigs, stepping up to the 40 mm bore increases the push force to 628 N. The base MBL uses a fixed rubber bumper to soften end-of-stroke impacts, but if your 75 mm stroke cycle runs too fast and requires deceleration, select the MBLC variant for its adjustable air cushion.
Keep in mind that a plain MBL does not hold its position or load when air pressure is lost or the valve is centered—the rod will drift or drop. The rubber bumper only absorbs impact; it is not a locking mechanism. If your machine requires fail-safe position holding, add an external rod lock or a pilot-operated check valve. This SKU uses a G1/8 port with a PT thread form and a rigid U flat-end rear 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 MBL32X75U FAQ
At 0.5 MPa, the 32 mm bore provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N, with a theoretical maximum of 82 kgf at 1.0 MPa. The double-acting operating speed ranges from 30-800 mm/s.
This specific SKU lacks the -S suffix, meaning it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL features a fixed rubber bumper, not an adjustable cushion; if you need end-of-stroke deceleration control, choose the MBLC variant instead.
