The AirTAC AirTAC MBL63X50SCA 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 MBL63X50SCA is a double-acting aluminum mini round cylinder engineered to deliver substantial thrust in spatially constrained environments. At 0.5 MPa, it generates 1558 N of push force and 1457 N of pull force, making it well-suited for high-force clamping over its 50 mm stroke. A built-in magnet allows integration with CMSG, DMSG, or EMSG sensor switches for precise end-position detection.
This SKU features a CA pivot back cover, enabling the cylinder body to swing on a pin to accommodate arcing or angular loads during movement. Internally, 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. The riveted rolling-packed barrel keeps the overall footprint small and lightweight, though it is not designed to be disassembled like a tie-rod cylinder.

Provides 1558 N of push force to eject dense plastic parts from injection molds, where the CA pivot back cover absorbs any slight misalignment during the initial breakaway.
Swings a heavy diverter arm on a packaging conveyor to sort dense cartons, utilizing the 50 mm stroke and pivot mounting to maintain smooth angular motion.
Holds thick sheet metal blanks securely in place before a stamping press cycles, relying on the 318 kgf maximum theoretical force to prevent workpiece shifting.
Selecting the MBL63X50SCA provides the maximum standard thrust available in the MBL family. If your application requires less force, stepping down to the 50 mm bore yields 981 N of push at 0.5 MPa, which avoids unnecessary load on your machine frame. Because this is the largest bore size, stepping up would require migrating to an ISO 15552 profile cylinder. This model uses a G1/4 port, PT thread form, M14x1.5 rod-end thread, and includes the -S magnet. If your process involves heavier moving masses and requires end-stroke deceleration, consider the MBLC variant with adjustable air cushioning instead of the base MBL's fixed rubber bumper.
Because the base MBL relies on a fixed rubber bumper rather than a locking mechanism, it cannot hold a load in place if air pressure is lost or the valve is centered; the rod will drift. For applications needing fail-safe position holding without live pressure, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 increases to 2181 N, with a maximum theoretical force of 318 kgf at 1.0 MPa. It uses a Ø16 mm rod with an M14x1.5 rod-end thread and a G1/4 port.
No, the base MBL features a fixed rubber bumper that softens end-of-stroke impacts and cannot be adjusted; for adjustable air cushioning, you would need the MBLC variant. The -S suffix indicates a built-in magnet, allowing you to mount CMSG reed or DMSG/EMSG electronic switches along the body for position sensing.
