The FGH6KK-2048G-90G-NG-J/50P encoder is a well-recognized heavy-duty model used across various steel production and rolling mill systems. To address the sourcing challenges of this model, we now offer a fully customized replacement solution built according to a 1:1 specification. Each replacement unit is designed to maintain identical output characteristics, ensuring compatibility with the existing installation without requiring any modification to mounting or wiring. Short production cycles help users resolve procurement delays and restore their systems quickly.
In demanding industrial environments such as steel mills, port cranes, and heavy conveyor systems, the FGH6KK series is known for its excellent stability, precision, and rugged construction. Our replacement version replicates these qualities with reinforced housing, high-temperature bearings, and corrosion-resistant sealing technology. It provides the same pulse accuracy and vibration endurance required for long-term reliable operation in tough field conditions.
