The AirTAC AirTAC MBL63X500SCA Mini Cylinder | 63mm Bore 500mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 500mm 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 MBL63X500SCA is a double-acting aluminum mini round cylinder engineered for tight spaces where high force is still required. It delivers a robust 1558 N push and 1457 N pull at 0.5 MPa, making this 63 mm bore, 500 mm stroke variant ideal for driving heavy slides or actuators across a wide span. The riveted rolling-packed barrel keeps the body light and compact, but it is not designed to be disassembled like a traditional tie-rod cylinder. A heterogeneous two-way piston seal retains grease internally for long service life, while the carbon-steel piston rod features 20 μm hard-chrome plating for superior wear and corrosion resistance.
This specific SKU includes the CA pivot (clevis) back cover, which allows the cylinder body to swing on a pin to accommodate arcing or angular loads during the 500 mm travel. It also features a built-in magnet (-S) for use with AirTAC CMSG, DMSG, and EMSG sensor switches to confirm end-of-stroke position. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impact; for adjustable air cushioning to handle faster or heavier moving masses, the MBLC variant is required.

Drives the heavy indexing arm of a textile loom, using the 1558 N push force at 0.5 MPa to shift large fabric beams across the 500 mm span while the CA pivot absorbs angular rod movement.
Actuates a heavy diverter gate on a packaging conveyor line, where the 2181 N thrust at 0.7 MPa easily overcomes friction to push loaded pallets laterally into a sorting lane.
Raises and lowers a mezzanine safety gate on a storage rack, utilizing the 500 mm stroke to clear the full aisle opening while the DMSG electronic sensor confirms gate closure.
Selecting this 63 mm bore provides the highest standard thrust in the MBL range, pushing 1558 N at 0.5 MPa. If your application needs less force, stepping down to the 50 mm bore yields 981 N of push force. Because this is the largest available bore, there is no larger MBL option; for even greater thrust, an ISO 15552 profile cylinder would be required. The 500 mm stroke is the maximum standard stroke available; any longer requirement up to 800 mm becomes a special made-to-order item. The CA pivot back cover is essential here, as the long 500 mm travel combined with a Ø16 rod means low side-load tolerance; an arcing mount or an external guide is strongly recommended to prevent rod-bearing bending. If rigid anti-rotation is needed, consider the MBLD double-rod type.
When replacing this unit, match the 63 mm bore, 500 mm stroke, G1/4 port size, PT thread form, CA pivot back cover, and the -S magnet. Note that a plain MBL does not hold its load if air pressure is lost or the valve is centered; the rod will drift. The rubber bumper only softens impact and is not a brake. If the load must be held without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
This 63 mm bore cylinder has a G1/4 port and an M14x1.5 rod-end thread. It outputs 1558 N push and 1457 N pull at 0.5 MPa, 2181 N push at 0.7 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper that cannot be adjusted. To manage end-of-stroke impact energy for faster or heavier moves, you must step up to the MBLC variant, which features an adjustable air cushion.
