The AirTAC AirTAC MBL63X20U Mini Cylinder | 63mm Bore 20mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 20mm 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 MBL63X20U is a double-acting aluminum mini round cylinder engineered for high-force actuation in severely space-constrained machinery. Delivering 1558 N of push force at just 0.5 MPa (and up to 2181 N at 0.7 MPa), this 63 mm bore unit uses a short 20 mm stroke to execute rapid, heavy-duty work like stamping or short-distance ejection. The U suffix designates a rigid flat-end rear cover, providing a solid, fixed mounting footprint that handles straight-line axial loads without inducing cylinder body sway.
Unlike tie-rod ISO 15552 profile cylinders, the MBL body features a riveted rolling-packed aluminum barrel where the front and rear covers are crimped directly to the tube, minimizing weight and footprint. Inside, 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 to resist wear and surface corrosion. Because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot support CMSG, DMSG, or EMSG position sensing.

Leverages the 1558 N push force at 0.5 MPa and 20 mm stroke to execute rapid, high-impact short-stroke forming of thin sheet metal enclosures.
Uses the 63 mm bore's 318 kgf maximum theoretical force to positively deflect heavy cast iron transfer cases off a high-speed packaging conveyor line.
Employs the rigid U flat-end back cover to securely lock a heavy PCB routing fixture in place, absorbing routing vibrations without pivot deflection.
If 1558 N at 0.5 MPa is more force than your application requires, stepping down to the 50 mm bore yields 981 N of push force while retaining the same G1/4 port and Ø16 mm rod. Conversely, the 63 mm bore is the largest available in the MBL series, so for even higher thrust demands you must transition to a larger profile cylinder. For applications needing end-of-stroke energy absorption for heavier moving masses, specify the MBLC variant, which replaces this model's fixed rubber bumper with an adjustable air cushion.
This MBL63X20U configuration uses a PT tapered port thread, a U flat-end back cover, and no magnet. Note that the fixed rubber bumper only softens end-of-stroke impact; it is not a locking mechanism. If the load must remain safely held in place when air pressure is lost or the valve is centered, an external rod lock or a pilot-operated check valve must be fitted to the system.
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 increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
No, because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot support CMSG, DMSG, or EMSG sensor switches. To use position sensing, you must select an MBL63X20S variant with the magnet included.
