The AirTAC AirTAC MBL63X175SU Mini Cylinder | 63mm Bore 175mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 175mm 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 MBL63X175SU is a double-acting aluminum mini round cylinder engineered for compact spaces requiring high thrust. It delivers a robust 1558 N push and 1457 N pull force at 0.5 MPa, utilizing a 63 mm bore and 175 mm stroke. The integrated U flat-end back cover provides a rigid rear mount for straightforward fixed installations.
This SKU includes a built-in magnet (-S) for direct compatibility with AirTAC CMSG reed and DMSG or EMSG solid-state sensor switches to verify rod position. The riveted rolling-packed barrel keeps the body lightweight and spatially efficient, while the carbon-steel piston rod features 20 um hard-chrome plating to resist wear and corrosion. A heterogeneous two-way piston seal permanently retains grease, extending operational lifespan in demanding environments.

Provides the 1558 N push force needed to eject dense plastic parts from tight mold voids where larger ISO 15552 cylinders cannot physically fit within the tooling envelope.
Drives a heavy diverter arm on a packaging conveyor, using the 175 mm stroke to shift boxed goods between lanes while the U flat-end cover handles the rigid mounting.
Utilizes the built-in magnet and DMSG solid-state sensor to confirm full press stroke on electronic connectors, ensuring proper crimping force before signaling the controller.
For applications needing less force, step down to the 50 mm bore (981 N push at 0.5 MPa); if you require more power, 63 mm is the largest standard MBL size available (1558 N push). The base MBL uses a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion—choose the MBLC variant if your heavy 318 kgf maximum moves require precise end-of-stroke deceleration. Additionally, a plain MBL cannot hold a load if air pressure drops; pair it with an external rod lock or pilot-operated check valve if position retention is critical.
With a 175 mm stroke on a Ø16 mm rod, the unsupported rod length is highly susceptible to side-load bending. To prevent premature seal wear and rod bearing failure, guide the load externally or pivot the cylinder using a CA back cover with an SDB bracket. For strict anti-rotation requirements, consider the MBLD double-rod alternative. This configuration uses a G1/4 port with PT thread form.
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 operating pressure.
No, the base MBL63X175SU uses a fixed rubber bumper to absorb end-of-stroke impact, which cannot be adjusted. If your application requires tunable deceleration for heavier moving masses, you must upgrade to the MBLC variant, which features an adjustable air cushion.
