About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175U
The AirTAC MBL40X175U is a double-acting aluminum mini round cylinder engineered for compact installations. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, making it well-suited for medium-duty positioning tasks across a 175 mm stroke. The U suffix denotes a flat-end rear cover, providing a rigid, fixed mounting footprint for straightforward inline actuation.
This model features a riveted rolling-packed barrel that crimps the front and rear covers directly to the tube, yielding a lightweight body that is not designed to be disassembled like a traditional tie-rod cylinder. Inside, a heterogeneous two-way piston seal retains grease for extended operational life, while the Ø16 mm carbon-steel piston rod is protected by a 20 µm hard-chrome plating to resist wear and corrosion. Because this SKU lacks the -S magnet suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175U Is Used
CNC Lathe Bar Feeder
Actuates the pusher arm to index raw bar stock into the spindle collet, utilizing the 628 N push force to overcome guide friction in a tight machine enclosure.
Packaging Carton Flap Folder
Folds minor flaps on small corrugated boxes moving along a conveyor, where the 175 mm stroke clears the packaging line rails without needing a larger profile cylinder.
PCB Router Z-Axis Gate
Raises and lowers a safety guard or dust extraction nozzle over a PCB routing spindle, relying on the rigid U flat-end rear cover to maintain strict perpendicular alignment.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X175U the Right Cylinder?
At 0.5 MPa, this 40 mm bore provides 628 N of push force. If your application requires less force, stepping down to the 32 mm bore yields 402 N of push force. If you need to move heavier payloads, stepping up to the 50 mm bore provides 981 N. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion; choose the MBLC variant if your cycle times demand adjustable end-cushioning for heavier moving masses.
With a 175 mm stroke, the unsupported Ø16 mm rod has a relatively low side-load tolerance. For arcing or angular loads, consider using an external guide rail or switching to the MBLD double-rod cylinder to prevent rod-bearing bending. Furthermore, this cylinder does not hold its load if air pressure is lost or the valve is centered—the rod will drift. Install an external rod lock or a pilot-operated check valve if the payload must remain safely suspended during an air loss event.
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 MBL40X175U FAQ
The 40 mm bore generates 628 N push and 528 N pull at 0.5 MPa, and 880 N push at 0.7 MPa, with a theoretical maximum of 128 kgf at 1.0 MPa. It uses a G1/4 port size with a PT tapered thread form, and the rod end features an M12x1.25 thread.
No. Because this SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper to absorb end-of-stroke impact; for adjustable air cushioning, you must specify the MBLC variant.
