The AirTAC AirTAC MBL50X450SU Mini Cylinder | 50mm Bore 450mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 450mm 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 MBL50X450SU is a double-acting aluminum mini round cylinder engineered for compact installations requiring a long 450mm stroke. Delivering 981N push and 881N pull force at 0.5MPa, it suits heavy-duty positioning within confined machine envelopes. The riveted rolling-packed barrel keeps the overall footprint and weight low, creating a rigid assembly that is not designed to be disassembled or rebuilt like a tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for direct mounting of AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensor switches to track rod position. It features a U flat-end back cover for rigid fixed mounting and a Ø16mm carbon-steel piston rod with 20μm hard-chrome plating for high wear resistance. The heterogeneous two-way piston seal retains grease internally, ensuring long operational life across the 30-800mm/s speed range.

Uses the 981N push force at 0.5MPa to deflect heavy pallets onto a secondary conveyor branch, fitting neatly into the tight transfer zone clearances.
Extends the full 450mm stroke to push packed cartons into a vertical palletizing station, relying on the rigid U flat-end back cover to resist deflection.
Deploys the long 450mm reach to extract molded plastic parts from deep machine cavities, tracking the cycle via a DMSG solid-state sensor on the -S magnet.
At 0.5MPa, this 50mm bore generates 981N of push force. If your application needs less force, stepping down to the 40mm bore yields 628N push. If you require more power, the 63mm bore provides 1558N push. Because this is a 450mm stroke, the unsupported Ø16mm rod has a high risk of bending under side loads—use an external guide, a CA pivot back cover, or the MBLD double-rod anti-rotation type to prevent premature seal wear.
The base MBL uses a fixed rubber bumper to soften end-of-stroke impacts, not an adjustable cushion screw (choose the MBLC variant for adjustable air cushioning). Note that a plain double-acting cylinder cannot hold a load if air pressure drops or the valve is centered; the rod will drift. Use an external rod lock or pilot-operated check valve for secure position holding. Replacement match: 50mm bore, 450mm stroke, G1/4 port, PT thread, U flat-end back cover, no mounting accessory, with -S magnet.
Quick checklist
At 0.5MPa, the 50mm bore provides 981N push and 881N pull force. At 0.7MPa, push increases to 1374N, with a maximum theoretical force of 200kgf at 1.0MPa. The operational speed range is 30-800mm/s.
No, the base MBL50X450SU uses a fixed rubber bumper to absorb end-of-stroke impacts. It does not have an adjustable cushion screw. If your heavy 450mm stroke requires adjustable air cushioning to prevent shock, select the MBLC variant.
