The front key for hydraulic MDR, code 4552113, is a mechanical coupling component specifically designed for Gildemeister GM20 multi-spindle automatic lathes, where it plays a critical role in torque transmission and precise positioning of rotating elements within the hydraulic MDR system.

Functionally, the key ensures a secure mechanical connection between shaft and mating component, enabling torque transmission without slippage while maintaining the required geometric alignment. In hydraulic MDR applications, this component is essential for ensuring synchronized movements and stable operation during high-repeatability machining cycles.

Manufactured from high-strength materials and precision-machined, the key features tight dimensional tolerances to ensure a secure fit without backlash. This is crucial to minimize vibrations, prevent premature wear, and avoid positioning errors during operation.

Its use is typically associated with maintenance operations, replacement of worn components, or restoration of original machine conditions. Full compliance with original specifications is essential to ensure performance continuity and operational safety.
