The AirTAC AirTAC MBL63X40U Mini Cylinder | 63mm Bore 40mm Stroke 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 MBL63X40U is a double-acting aluminum mini round cylinder engineered to deliver substantial thrust in tight machine envelopes. At 0.5 MPa it provides 1558 N push and 1457 N pull force, making this 63 mm bore, 40 mm stroke unit ideal for heavy-duty compact actuation. The U suffix denotes a rigid flat-end rear cover for secure fixed mounting.
Inside this non-ISO cylinder, a heterogeneous two-way piston seal retains grease for long service life, while the Ø16 mm carbon-steel piston rod features 20 µm hard-chrome plating for wear resistance. The body uses a riveted rolling-packed aluminum barrel that keeps weight down but cannot be disassembled. This specific SKU lacks a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors.

Provides 1558 N of push force to eject small metal blanks from a tight progressive die station, fitting where a larger tie-rod cylinder would stall.
Acts as a rigid U-mount stopper block to halt heavy cardboard cartons on a 40 mm stroke conveyor line before pallet loading.
Exerts 1457 N of pull force to secure PCB panels against a router fixture, absorbing vibration via the fixed rubber bumper during high-speed routing.
For less force, step down to the 50 mm bore which yields 981 N push at 0.5 MPa; if you need even more power, note that 63 mm is the largest standard MBL bore offering 1558 N. If your application requires adjustable end-of-stroke cushioning rather than the fixed rubber bumper found here, select the MBLC variant. Because this model has no -S suffix, a position sensor cannot be fitted.
This cylinder uses a G1/4 port and an M14x1.5 rod-end thread. Remember that a plain MBL does not hold its load when air pressure is lost or exhausted—the rod will drift. Use an external rod lock or pilot-operated check valve if position holding is required.
Quick checklist
At 0.5 MPa it provides 1558 N push and 1457 N pull force. At 0.7 MPa the push force is 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
This base MBL model uses a fixed rubber bumper to soften end-of-stroke impact and cannot be adjusted (choose the MBLC variant for adjustable air cushion). Additionally, this SKU lacks a built-in magnet, so CMSG, DMSG, or EMSG sensor switches cannot be installed.
