The AirTAC AirTAC MBL63X30SU Mini Cylinder | 63mm Bore 30mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 30mm 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 MBL63X30SU is a double-acting aluminum mini round cylinder engineered to deliver substantial thrust in tight machine spaces. Operating at 0.5 MPa, it provides 1558 N of push force and 1457 N of pull force, escalating to 2181 N at 0.7 MPa. This 63 mm bore unit uses a G1/4 port and a 30 mm stroke, making it highly effective for short, powerful clamping or ejection tasks. The built-in magnet (-S) enables direct compatibility with AirTAC CMSG reed and DMSG or EMSG solid-state sensor switches for precise end-of-stroke detection.
Unlike tie-rod ISO 15552 profile cylinders, the MBL body features a riveted rolling-packed aluminum barrel where the front and rear covers are crimped directly to the tube. This guarantees a lightweight, compact footprint but means the cylinder is not designed to be disassembled or rebuilt in the field. The U flat-end back cover provides a rigid, fixed mounting base, while the heterogeneous two-way piston seal retains grease internally for prolonged operational life. The carbon-steel piston rod is hardened with 20 um of chrome plating to resist wear and surface corrosion.

Uses the 1558 N push force at 0.5 MPa to knock finished plastic parts out of tight mold cavities where a full-size profile cylinder would not fit.
Employs the 30 mm stroke and DMSG electronic sensor feedback to rapidly deflect heavy glass containers between packaging lanes without stalling.
Leverages the 318 kgf maximum theoretical force to lock heavy stamping dies in place beneath small press brakes, utilizing the rigid U flat-end rear mount.
For applications requiring less force, stepping down to the 50 mm bore yields 981 N of push at 0.5 MPa, whereas moving up is not possible as 63 mm is the largest MBL size. If your cycle speeds are high and the fixed rubber bumper cannot absorb the end-of-stroke impact adequately, transition to the MBLC variant, which features an adjustable air cushion. Because the base MBL uses a fixed rubber bumper rather than a locking mechanism, the rod will drift or drop if air pressure is lost or the valve is centered; always integrate an external pilot-operated check valve if the load must be held safely in place.
This specific SKU includes a built-in magnet for position sensing, a U flat-end rigid back cover, and a default PT tapered port thread. If your layout requires the cylinder body to swing on a pin to accommodate arcing or angular motion, select the CA pivot back cover instead of the U type. With a short 30 mm stroke, side-load stress on the 16 mm rod is minimal, but any future upgrades to longer movements should incorporate an external guide or the MBLD double-rod anti-rotation type.
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 maximum theoretical force is 318 kgf at 1.0 MPa, which is the upper operating pressure limit.
No, the base MBL63X30SU uses a fixed rubber bumper to soften end-of-stroke impact and does not feature an adjustable cushion screw. If your application requires end-stroke speed regulation, you must upgrade to the MBLC variant, which includes an adjustable air cushion.
