The AirTAC AirTAC MBL63X300SCA Mini Cylinder | 63mm Bore 300mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 300mm 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 MBL63X300SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. At its 0.5 MPa operating point it generates 1558 N of push force and 1457 N of pull force, making this 300 mm stroke unit well suited for moving heavier jigs or workpieces through a long travel path. The riveted rolling-packed barrel keeps the overall footprint and weight low, though the crimped front and back covers mean this body style is not designed to be unbolted and rebuilt like a standard tie-rod cylinder.
This specific SKU includes a CA pivot back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads during that extended travel. The integrated -S magnet enables position detection using AirTAC CMSG reed or DMSG and EMSG solid-state sensor switches. Inside, a heterogeneous two-way piston seal retains lubrication, while the Ø16 mm carbon-steel rod features 20 um hard-chrome plating to resist wear and corrosion.

Uses the 1558 N push force at 0.5 MPa to shove heavy loaded pallets onto a parallel conveyor line, relying on the CA pivot to absorb the angular load as the 300 mm stroke extends.
Pushes raw steel bar stock into the collet chuck over a 300 mm travel, using the DMSG solid-state sensor to confirm the material has reached the machining start position.
Folds heavy corrugated cardboard blanks during high-speed case erecting, where the compact riveted aluminum barrel fits neatly within the tight machine frame clearance.
Selecting the 63 mm bore makes sense when your application requires moving substantial mass, as it outputs 1558 N push force at 0.5 MPa. If you need less force to save space, the 50 mm bore neighbor provides 981 N of push force. Stepping up is generally not required within the MBL family, as 63 mm is the largest available bore, delivering a maximum theoretical output of 318 kgf at 1.0 MPa. For faster or heavier moves that risk end-stroke impact, consider the MBLC variant which replaces the fixed rubber bumper with an adjustable air cushion.
With a 300 mm stroke, the unsupported Ø16 mm rod is highly susceptible to bending under side loads; the CA pivot back cover on this SKU is essential for arcing motions, but you should still use an external guide or an MBLD double-rod anti-rotation type for strictly linear heavy lifting. Remember that a plain MBL does not hold its position if air pressure is lost or the valve is centered, as the rod will drift or drop, so fit an external rod lock or pilot-operated check valve if safety requires it. This exact replacement matches: 63 mm bore, 300 mm stroke, G1/4 port, PT thread, CA pivot back cover, and a built-in magnet.
Quick checklist
This 63 mm bore double-acting cylinder delivers a push force of 1558 N and a pull force of 1457 N at 0.5 MPa. At 0.7 MPa, the push force increases to 2181 N, with a maximum theoretical output of 318 kgf at 1.0 MPa. It operates at a speed range of 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to soften the impact at the end of the stroke, which cannot be adjusted. If your application requires tunable end-of-stroke deceleration for heavier moving loads, you should step up to the AirTAC MBLC variant which features an adjustable air cushion.
