The AirTAC AirTAC MBL63X40SCA Mini Cylinder | 63mm Bore 40mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 40mm 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 MBL63X40SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it delivers a substantial push force of 1558 N and a pull force of 1457 N, making this 40 mm stroke variant ideal for heavy-duty clamping and short-stroke ejection tasks.
This SKU includes a built-in magnet (-S) for CMSG, DMSG, or EMSG sensor switches to track rod position, and a CA pivot back cover that swings on a pin to accommodate arcing loads. The riveted rolling-packed barrel keeps the body light, while the carbon-steel rod features 20 um hard-chrome plating to resist wear and corrosion.

Provides 1558 N of push force at 0.5 MPa to positively eject dense plastic parts from tight mold cavities where larger standard cylinders cannot fit.
The CA pivot back cover allows the cylinder to swing a heavy diverting arm smoothly on a pin, absorbing angular loads during high-speed pallet routing.
The integrated -S magnet works with DMSG solid-state sensors to confirm ram extension on small pneumatic presses, ensuring precise 40 mm end-of-stroke positioning.
As the largest bore in the MBL series, stepping down to the 50 mm bore reduces the 0.5 MPa push force to 981 N if your application requires less thrust or a smaller footprint. Because this base MBL uses a fixed rubber bumper rather than an adjustable air cushion, heavier moving masses at higher speeds should be upgraded to the MBLC variant. Note that a plain MBL does not hold its position if air pressure is lost; a load that must be locked in place without live pressure requires an external rod lock or pilot-operated check valve. For replacement, match the 63 mm bore, 40 mm stroke, G1/4 port, PT thread, CA pivot back cover, and -S magnet.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N push and 1457 N pull. At 0.7 MPa, the push force increases to 2181 N, with a theoretical maximum of 318 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact. If your application requires adjustable air cushioning for heavier loads or faster speeds, you need the MBLC variant.
