The AirTAC AirTAC MBL63X15SCA Mini Cylinder | 63mm Bore 15mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm 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 MBL63X15SCA is a double-acting aluminum mini round cylinder engineered for tight machine spaces. Delivering 1558 N of push force at 0.5 MPa over a short 15 mm stroke, it is built for heavy-duty compact tasks. The riveted rolling-packed barrel crimps the covers to the tube, yielding 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 carbon-steel piston rod features 20 um hard-chrome plating for wear and corrosion resistance.
This specific SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG (reed) and DMSG/EMSG (electronic) sensor switches to detect rod position. It also features a CA pivot back cover, allowing the cylinder to swing on a pin to accommodate arcing or angular loads. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion (which requires the MBLC variant).

Provides 1558 N of push at 0.5 MPa to eject small stamped metal parts from tight die cavities, using the CA pivot cover to absorb angular die misalignment.
Swings a diverter arm on a packaging conveyor using its 15 mm stroke and clevis mount, handling high-speed routing with CMSG sensor confirmation.
Acts as a heavy-duty stop block for pallets on a compact assembly line, leveraging the 318 kgf max theoretical force to halt loads abruptly.
At 63 mm, this is the largest standard MBL bore. If you need less force, step down to the 50 mm bore, which provides 981 N of push force at 0.5 MPa. Because this is the top size, there is no larger MBL option; for even higher thrust, an ISO 15552 profile cylinder would be required. Choose the MBLC variant if your heavy 318 kgf moves require adjustable air cushioning, or the MSBL/MTBL single-acting models if you only need spring-return push or pull action.
Because the CA back cover pivots, it helps manage angular stresses on this short 15 mm stroke. Note that a plain MBL does not hold its load when air pressure is lost or the valve is centred; the rod will drift or drop. Use an external rod lock or pilot-operated check valve if the load must be held safely without live pressure. Replacement parts require matching the 63 mm bore, 15 mm stroke, G1/4 port, PT thread, CA pivot cover, and -S magnet.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push force is 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion. If your application requires adjustable cushioning for heavier or faster moves, you should select the MBLC variant instead.
