The AirTAC AirTAC MBL63X40SU Mini Cylinder | 63mm Bore 40mm 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 MBL63X40SU is a compact double-acting aluminum mini round cylinder engineered to deliver substantial thrust in confined machinery spaces. Operating at 0.5 MPa, it provides 1558 N of push force and 1457 N of pull force across its 40 mm stroke. This genuine AirTAC component features a built-in magnet for position detection and a rigid U flat-end rear cover for straightforward fixed mounting.
Unlike heavier tie-rod bodies, this unit utilizes a riveted rolling-packed aluminum barrel where the covers are crimped to the tube, creating a lightweight, permanently sealed assembly. The carbon-steel piston rod features 20 μm hard-chrome plating to resist wear and corrosion, while a heterogeneous two-way piston seal retains grease for extended operational life. It relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable cushion.

Provides the high 1558 N push force needed to eject dense plastic parts from tight mold voids where standard profile cylinders cannot fit.
Actuates a heavy routing gate on a compact packaging conveyor, using the 40 mm stroke to clear the lane before returning via the 1457 N pull force.
Holds delicate printed circuit boards under a specific clamping force during automated soldering, relying on the -S magnet to confirm clamp engagement.
Selecting the MBL63X40SU is ideal when your application demands the highest standard thrust in the MBL range but has a very short active travel requirement. If you need to step down to reduce mass or cycle volume, the 50 mm bore offers 981 N of push force at 0.5 MPa. Since 63 mm is the largest bore in this mini series, stepping up beyond 318 kgf of maximum force requires moving to a larger profile cylinder such as the SAI ISO 15552 line.
The included -S magnet allows integration with AirTAC CMSG reed or DMSG/EMSG electronic switches for end-of-stroke confirmation. Remember that a plain double-acting cylinder drifts when air pressure is lost; the rubber bumper softens impact but does not lock the rod, so fit an external pilot-operated check valve if you must hold a load safely during an air failure. For exact replacement, match the 63 mm bore, 40 mm stroke, G1/4 port, PT thread, U back cover, and the -S magnet.
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 increases to 2181 N. The theoretical maximum force is 318 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
The base MBL uses a fixed rubber bumper that cannot be adjusted; if you need adjustable air cushioning for heavier loads, you must use the MBLC variant. However, this MBL63X40SU includes a built-in magnet (-S), so it is fully compatible with AirTAC CMSG, DMSG, and EMSG sensor switches for rod position detection.
