About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X130U
The AirTAC MBL40X130U is a double-acting aluminum mini round cylinder engineered for tight machinery spaces where a larger profile cylinder cannot fit. It delivers a robust 628 N push and 528 N pull force at 0.5 MPa, making this 130 mm stroke variant well-suited for mid-range part ejection or robust clamping tasks. The U suffix denotes a rigid flat-end rear cover that mounts flush against machine frames to resist axial shifting. This genuine AirTAC component features a riveted rolling-packed barrel that crimps the front and rear covers directly to the tube, permanently locking the lightweight aluminum body together.
Because this specific SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch. Inside, a heterogeneous two-way piston seal continuously retains grease for long operational life, while the Ø16 mm carbon-steel piston rod features 20 µm hard-chrome plating to resist wear and corrosion in dynamic environments.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X130U Is Used
CNC Lathe Bar Ejection
Uses the 628 N push force at 0.5 MPa to reliably eject cut bar stock from a CNC lathe spindle, fitting easily into the tight clearance of the machine enclosure.
Carton Flap Folding
The 130 mm stroke provides the exact linear travel needed to fold corrugated carton flaps on a packaging line prior to tape sealing, driven by a compact riveted body.
PCB Router Clamping
Applies 528 N of pull force to secure PCB panels against a router fixture's flat-end U cover, preventing vibration during high-speed depaneling without occupying deck space.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X130U the Right Cylinder?
If your application requires less force, stepping down to the 32 mm bore yields 402 N of push at 0.5 MPa; conversely, stepping up to the 50 mm bore provides 981 N for heavier loads. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact, but if your process demands faster cycling with heavier masses, the MBLC variant offers an adjustable air cushion. For single-direction spring-return tasks, consider the MSBL or MTBL series.
At 130 mm of stroke, the Ø16 mm rod is highly susceptible to side-load bending and bearing wear. To prevent premature seal failure, use an external guide rail, select a CA pivot back cover for arcing loads, or switch to the MBLD double-rod cylinder for anti-rotation. Note that this cylinder does not hold its load if air pressure is lost; the rod will drift. Use an external pilot-operated check valve for drop prevention. Replacement match: 40 mm bore, 130 mm stroke, G1/4 port, PT thread, U flat-end back cover, 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 MBL40X130U FAQ
The 40 mm bore generates 628 N push and 528 N pull at 0.5 MPa, 880 N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa. The 130 mm stroke falls within the standard range, which extends to a maximum of 500 mm.
No. This specific SKU lacks the -S magnet suffix, so it cannot accept CMSG, DMSG, or EMSG electronic or reed sensor switches. Additionally, the base MBL relies on a fixed rubber bumper to absorb end-of-stroke impact; it does not have an adjustable cushion screw. For adjustable air cushioning, choose the MBLC variant.
