The AirTAC AirTAC MBL63X200SU Mini Cylinder | 63mm Bore 200mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 200mm 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 MBL63X200SU is a double-acting aluminum mini round cylinder engineered for heavy pushing in confined machinery spaces. Operating at 0.5 MPa, it generates 1558 N of push force and 1457 N of pull force, utilizing a 200 mm stroke to cycle components rapidly. The U flat-end back cover provides a rigid, fixed rear mounting surface for straightforward integration into stationary frames.
This SKU includes a built-in magnet (-S) for direct compatibility with AirTAC CMSG reed and DMSG or EMSG solid-state sensor switches, enabling precise end-of-stroke detection. To maintain a small footprint, the aluminum barrel is riveted and rolling-packed, meaning the covers are crimped to the tube rather than secured with heavy tie rods. The Ø16 mm carbon-steel piston rod features 20 µm hard-chrome plating to resist wear and corrosion, while the heterogeneous two-way piston seal retains grease for a long service life. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion screw.

Uses the 1558 N push force at 0.5 MPa to swing a heavy diverter arm on a packaging conveyor, routing dense cartons at high speed within a cramped transfer station.
Cycles a sliding safety door on a CNC lathe across the 200 mm stroke, relying on the -S magnet and DMSG electronic switch to confirm door closure before the spindle starts.
Ejects finished metal stampings from a stacking fixture, using the rigid U flat-end back cover to bolt directly to the machine subplate without requiring a pivot bracket.
As the largest bore in the MBL series, the 63 mm size offers the maximum available thrust for this compact family. If you need slightly less force and a tighter footprint, stepping down to the 50 mm bore drops the 0.5 MPa push force to 981 N. Because this 63 mm bore pushes with 1558 N at 0.5 MPa (and up to 2181 N at 0.7 MPa), ensure your frame can handle the load without flexing. The fixed rubber bumper softens end-of-stroke impacts, but if your application involves fast cycling or heavy moving masses, upgrading to the MBLC variant provides an adjustable air cushion to decelerate the rod more smoothly.
With a 200 mm stroke driven by a Ø16 mm rod, the unsupported rod length is significant; mini cylinders have low side-load tolerance, so an external guide rail is strongly recommended to prevent rod-bearing bending. Note that this cylinder does not hold its position if air pressure is lost or the valve is centered—the rod will drift under load. For position holding without live pressure, install an external pilot-operated check valve or a dedicated rod lock. Replacement or matching parts must specify a 63 mm bore, 200 mm stroke, G1/4 port size, PT thread form, U flat-end back cover, and the -S magnet.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder outputs 1558 N of push force and 1457 N of pull force. Increasing the pressure to 0.7 MPa raises the push force to 2181 N. The theoretical maximum force is 318 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL features a fixed rubber bumper that absorbs end-of-stroke impact and cannot be adjusted. If your application requires tunable deceleration for heavy moving masses, you must select the MBLC variant, which incorporates an adjustable air cushion.
