About the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X10U
The AirTAC MBL40X10U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. With a 40mm bore and 10mm stroke, it generates 628N of push force and 528N of pull force at 0.5 MPa. The U flat-end back cover provides a rigid fixed mounting surface, ideal for short-stroke ejection tasks where rear pivot swing is unnecessary.
This SKU lacks a built-in magnet, meaning it cannot accept CMSG, DMSG, or EMSG sensor switches for rod position detection. The riveted rolling-packed barrel permanently crimps the covers to the tube, yielding a lightweight footprint but making the body non-serviceable compared to tie-rod designs. Impact absorption at end-of-stroke relies on a fixed rubber bumper rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X10U Is Used
Stamping Press Ejector
Uses the 628N push force at 0.5 MPa to kick small stamped metal blanks out of a die in a 10mm rapid burst before the press opens.
PCB Router Clamping
Secures printed circuit boards during routing with a rigid U flat-end mount, using the short 10mm stroke to lock the panel instantly.
Carton Flap Tucking
Tucks inner flaps on small packaging lines where the 40mm bore provides enough force without the bulk of a 50mm body.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL40X10U the Right Cylinder?
Select this 40mm bore when a 32mm cylinder (402N push @0.5 MPa) lacks the power to move a load, but a 50mm cylinder (981N push @0.5 MPa) is physically too large for the envelope. The 10mm stroke is tailored for micro-movements like part ejection or brief clamping. If your cycle speed creates severe end-of-stroke shock, step up to the MBLC variant for its adjustable air cushion. Remember that the fixed rubber bumper only softens impact; it does not hold the load. If pressure drops, the rod will drift, so add an external pilot-operated check valve if position retention is required.
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 MBL40X10U FAQ
This 40mm bore cylinder features a G1/4 port and a Ø16mm rod with an M12x1.25 thread. It outputs 628N push / 528N pull at 0.5 MPa, 880N push at 0.7 MPa, and a maximum theoretical force of 128 kgf at 1.0 MPa.
No. Because this SKU lacks the -S suffix, it has no internal magnet and cannot mount CMSG, DMSG, or EMSG sensor switches. Additionally, it uses a fixed rubber bumper for end-of-stroke absorption; for adjustable air cushioning, you must specify the MBLC variant.
