The AirTAC AirTAC MBL63X500SU 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 MBL63X500SU is a double-acting aluminum mini round cylinder engineered for heavy-duty clamping within tight machine footprints. Delivering 1558 N of push force at 0.5 MPa and 2181 N at 0.7 MPa, this 63 mm bore unit manages substantial loads despite its compact riveted rolling-packed barrel. The 500 mm stroke provides extensive reach for automated assembly lines. Because the front and rear covers are crimped directly to the aluminum tube, the body remains lightweight and spatially efficient, though it is not designed to be disassembled and rebuilt like a standard tie-rod cylinder.
This specific SKU includes a U flat-end back cover for rigid fixed mounting and a built-in magnet (-S) for non-contact position detection using AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches. The carbon-steel piston rod features a 20 um hard-chrome plating to resist wear and corrosion, while a heterogeneous two-way piston seal retains grease internally for a long service life. The cylinder relies on a fixed rubber bumper to soften end-of-stroke impact; it is not an adjustable air cushion. For applications needing softer end-stroke deceleration at these high forces, the MBLC variant is required.

Provides the 1558 N push force required to eject dense plastic parts from injection molds where machine clearance prohibits larger profile cylinders.
Uses the 500 mm stroke to extend heavy diversion arms across wide packaging conveyor belts, relying on the -S magnet to confirm arm reach.
Applies 2181 N of clamping pressure at 0.7 MPa to secure populated circuit boards during automated ICT testing, using the U flat-end cover for rigid mounting.
Selecting this 63 mm bore provides 1558 N push and 1457 N pull force at 0.5 MPa. If your application requires less force, stepping down to the 50 mm bore yields 981 N push and 881 N pull. Since this is the largest standard MBL diameter, moving up in force requires migrating to an ISO 15552 profile cylinder. The base MBL is double-acting, meaning air both extends and retracts the rod; if you need spring-return push or pull mechanics in smaller bores (20-40 mm), consider the MSBL or MTBL single-acting versions. This MBL63X500SU uses a G1/4 port, an M14x1.5 rod-end thread, a PT tapered port thread form, and a U flat-end back cover.
At 500 mm of stroke, the Ø16 mm piston rod is highly susceptible to bending under side loads. To prevent premature rod-seal failure or rod-bearing wear, you must use an external linear guide, a CA pivot back cover, or the MBLD double-rod anti-rotation type. Additionally, this cylinder cannot hold a load if air pressure is lost or the valve is centered; the rod will drift. To maintain position without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the 63 mm bore provides 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push force reaches 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa, which is the upper operating pressure limit.
No. The base MBL63X500SU uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable cushion screw. If your application involves high moving masses and requires adjustable end-stroke deceleration, you should select the MBLC variant, which features an adjustable air cushion.
