Ball Screws Explaining Load Capacity Precision Ball

Oct 25, 2019 The dynamic load capacity (DLC) is simply a load rating. Its the load for a (theoretical) life of 1 million revolutions (ISO/JIS standard) or for 1 million inches of travel (ANSI standard). The DLC is critical for making lifetime calculations, since the expected life goes as the cube of the ratio of DLC to actual load.
