The AirTAC AirTAC MBL50X15U Mini Cylinder | 50mm Bore 15mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 15mm 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 MBL50X15U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 981 N push force at 0.5 MPa, making this 50 mm bore, 15 mm short-stroke unit ideal for high-impact pressing and ejecting. The U flat-end back cover provides a rigid fixed rear mounting surface for straightforward attachment. This genuine AirTAC actuator uses a riveted rolling-packed barrel where the covers are crimped to the tube, ensuring a lightweight body that is not designed to be disassembled like a tie-rod cylinder.
Inside, a heterogeneous two-way piston seal retains grease for long service life, while the Ø16 mm carbon-steel piston rod features 20 μm hard-chrome plating for wear and corrosion resistance. Because this SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion. Note that this bumper only absorbs shock; it does not hold the load if air pressure is lost.

Related variants: MBLC (adjustable cushion), MBLD (double rod), MBLJ (adjustable stroke), MSBL/MTBL (single acting).
Fits inside tight mold bases to provide a fast 981 N ejection strike for small plastic parts over a 15 mm travel.
Drives short-stroke folding heads in compact packaging lines where a rigid U flat-end mount handles the high impact.
Delivers a precise 15 mm stroke to seat electronic connectors onto circuit boards without crushing the housing.
This 50 mm bore provides 981 N push and 881 N pull at 0.5 MPa. If your application needs less force, step down to the 40 mm bore (628 N push), or if you require more power, the 63 mm bore offers 1558 N push. For this 15 mm stroke, the U flat-end back cover gives a rigid fixed mount. If your mechanism needs angular alignment, switch to the CA pivot back cover. If you need adjustable end-position damping for faster cycles, select the MBLC variant instead of the fixed rubber bumper.
The MBL50X15U uses a G1/4 port (PT thread form) and an M14x1.5 rod end. Since this SKU has no -S magnet, position sensing is impossible. If you need end-of-stroke confirmation, order the -S option for CMSG reed or DMSG/EMSG solid-state switches. Remember, the rubber bumper is not a brake; if the rod must hold position without live air pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
At 0.5 MPa it provides 981 N push and 881 N pull. At 0.7 MPa the push force is 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
No. The MBL50X15U lacks the -S suffix, meaning it has no built-in magnet. You must select an MBL50 model with the -S option to use CMSG, DMSG, or EMSG sensor switches.
