The AirTAC AirTAC MBL63X50U Mini Cylinder | 63mm Bore 50mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 50mm 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 MBL63X50U is a compact double-acting aluminum mini round cylinder engineered to deliver substantial thrust in confined machinery spaces. Operating at 0.5 MPa, it provides 1558 N of push force and 1457 N of pull force, making this 63 mm bore, 50 mm stroke variant ideal for heavy-duty clamping and short-stroke ejection tasks. The U suffix designates a flat-end rigid rear cover for direct mounting.
Unlike tie-rod bodies, this unit utilizes a riveted rolling-packed aluminum barrel where the covers are crimped to the tube, ensuring a lightweight yet durable envelope that is not designed to be disassembled. Internal longevity is handled by a heterogeneous two-way piston seal that retains grease, paired with a carbon steel rod featuring 20 um hard-chrome plating for wear resistance. Because this specific SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Uses the 1558 N push force at 0.5 MPa to knock stamped metal blanks out of tight progressive die assemblies quickly.
Leverages the short 50 mm stroke and rigid U flat-end mounting to push heavy pallets onto secondary packaging lines.
Secures dense printed circuit board panels during routing operations where a compact 63 mm bore footprint is required.
Selecting this 63 mm bore provides 1558 N push force at 0.5 MPa; if your application requires less force, stepping down to the 50 mm bore yields 981 N, while no larger standard MBL bore exists for higher force demands. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion, so if your 50 mm move involves high kinetic energy, consider the MBLC variant for adjustable cushioning. Note that a plain MBL does not hold its position or load when air pressure is lost or the valve is centered, as the rod will drift or drop; an external rod lock or pilot-operated check valve is required for static holding.
Quick checklist
At 0.5 MPa, the push force is 1558 N and the pull force is 1457 N. At 0.7 MPa, the push force reaches 2181 N. The theoretical maximum force is 318 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
This specific SKU lacks the -S magnet suffix, so it cannot accept CMSG, DMSG, or EMSG sensor switches. Additionally, the base MBL uses a fixed rubber bumper for end-of-stroke impact absorption rather than an adjustable cushion screw; choose the MBLC variant if you need adjustable air cushioning.
