The AirTAC AirTAC MBL50X200SU Mini Cylinder | 50mm Bore 200mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 200mm 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 MBL50X200SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 981 N push force at 0.5 MPa across its 200 mm stroke, making it well-suited for moving heavier jigs or workpieces. The riveted rolling-packed barrel keeps the overall body light and small, though it is not designed to be disassembled and rebuilt like a traditional tie-rod cylinder. This specific SKU includes a U flat-end back cover for rigid fixed mounting and a built-in magnet (-S) for non-contact position detection.
Inside, a heterogeneous two-way piston seal retains grease for long operational life, while the Ø16 mm carbon-steel piston rod features 20 μm hard-chrome plating to resist wear and corrosion. The base MBL uses a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion. Because the U cover provides a rigid rear mount, you should ensure the load moves linearly to avoid bending the unsupported 200 mm rod.

Pushes a loaded 200 mm pallet shuttle in tight CNC enclosures, using its 981 N thrust to overcome guide friction without needing a large profile cylinder.
Drives a folding mechanism on packaging lines where the U flat-end cover provides a rigid rear anchor point for the 200 mm arc motion.
Actuates a routing flap on a conveyor system, relying on the -S magnet and a DMSG solid-state switch to confirm package diversion position.
If your application requires less force, stepping down to the 40 mm bore provides 628 N push at 0.5 MPa, while stepping up to the 63 mm bore yields 1558 N for heavier demands. For faster cycle speeds carrying this 200 mm stroke mass, consider the MBLC variant which adds an adjustable air cushion to absorb kinetic energy. The MBL50X200SU uses a G1/4 port with a PT thread form, a U flat-end back cover, and includes the -S magnet for CMSG, DMSG, or EMSG sensor switches. Remember that a plain MBL does not hold its load if air pressure drops or the valve is centered; the rod will drift. Use an external pilot-operated check valve if the load must be held.
At 200 mm of stroke, the small Ø16 mm rod has limited tolerance for side loads. To prevent rod-bearing bending and premature seal wear, guide the load externally or switch to the MBLD double-rod cylinder for anti-rotation support.
Quick checklist
At 0.5 MPa it provides 981 N push and 881 N pull force. At 0.7 MPa the push force is 1374 N, with a maximum theoretical force of 200 kgf at 1.0 MPa. This model uses a fixed rubber bumper, not an adjustable air cushion (which is found on the MBLC variant).
Yes, the -S suffix indicates a built-in magnet. It is designed to work with AirTAC CMSG reed switches, as well as DMSG and EMSG electronic solid-state sensors for rod position detection.
