The AirTAC AirTAC MBL63X225U Mini Cylinder | 63mm Bore 225mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 225mm 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 MBL63X225U is a double-acting aluminum mini round cylinder engineered for compact spaces requiring substantial thrust. Operating at 0.5 MPa, it delivers 1558 N of push force and 1457 N of pull force over a 225 mm stroke. The U suffix designates a rigid flat-end rear cover for direct fixed mounting.
Unlike tie-rod bodies, this cylinder features a riveted rolling-packed barrel where the covers are crimped to the tube, creating a lightweight, permanently sealed unit not designed for disassembly. It relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable cushion. Note that because this specific SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.

Provides the 1558 N push force needed to eject dense plastic parts from tight mold cavities where standard profile cylinders cannot fit.
Drives heavy cardboard carton diverting gates over a 225 mm stroke, relying on the rigid U flat-end rear cover for stable foot mounting.
Lifts localized product totes within compact packaging cells, using the 0.7 MPa thrust of 2181 N to overcome initial static friction.
Delivering 1558 N at 0.5 MPa, this 63 mm bore is the largest in the MBL family. If your application requires less force, step down to the 50 mm bore which provides 981 N of push force. As the largest available mini round body, there is no larger MBL option; for even higher loads, an ISO 15552 profile cylinder would be required. The base MBL design does not hold position if air pressure is lost; use an external pilot-operated check valve if load holding is critical.
For replacement matching, confirm the 63 mm bore, 225 mm stroke, G1/4 port size, PT thread form, and U flat-end back cover. Because the 225 mm stroke is substantial, the Ø16 mm piston rod is susceptible to bending under side loads; utilize an external guide rail or consider the MBLD double-rod anti-rotation type to prevent rod bearing wear.
Quick checklist
At 0.5 MPa, the push force is 1558 N and the pull force is 1457 N. At 0.7 MPa, the push force reaches 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa. The 63 mm bore supports standard strokes up to 500 mm, so the 225 mm stroke is a standard configuration.
This base MBL model uses a fixed rubber bumper to absorb end-of-stroke impact and cannot be adjusted. If you need adjustable air cushioning, select the MBLC variant. Additionally, because this specific SKU lacks the -S magnet suffix, it cannot support CMSG, DMSG, or EMSG electronic sensor switches for rod position detection.
