The AirTAC AirTAC MBL50X125SU Mini Cylinder | 50mm Bore 125mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 125mm stroke, G1/4 air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL50X125SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It features a 50mm bore and 125mm stroke, generating 981N of push force at 0.5MPa. The riveted rolling-packed barrel design keeps the body exceptionally light and compact, making it ideal where a larger profile cylinder cannot fit.
This SKU includes a built-in magnet (-S) for position sensing via CMSG, DMSG, or EMSG switches. The U flat-end back cover provides rigid fixed mounting. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the carbon-steel rod is protected by 20um hard-chrome plating to resist wear and corrosion.

Related variants: MBLC (adjustable cushion), MBLD (double rod), MBLJ (adjustable stroke), MSBL/MTBL (single acting).
Pushes lightweight pallets sideways at 981N push force, fitting neatly into the tight spacing between adjacent conveyor belts.
Actuates safety gates or interlocking covers on machining centers, using the integrated magnet for DMSG sensor confirmation.
Folds top flaps on mid-size packaging lines, relying on the rigid U flat-end back cover to withstand repetitive axial impacts.
Stepping down to the 40mm bore reduces the 0.5MPa push force to 628N, whereas stepping up to the 63mm bore raises it to 1558N. If your application requires adjustable end-of-stroke cushioning for heavier moving masses, select the MBLC variant instead of the base MBL.
This model uses a G1/4 port, PT thread form, M14x1.5 rod end, and a U flat-end back cover. The fixed rubber bumper softens impact but does not lock the rod; if you must hold a load without live air pressure, install an external pilot-operated check valve or rod lock. For replacement, match these exact specifications.
Quick checklist
At 0.5MPa it provides 981N push and 881N pull. At 0.7MPa the push force is 1374N, with a maximum theoretical force of 200kgf at 1.0MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact. If you need adjustable air cushioning for heavier loads, choose the MBLC variant.
