Footnote dynamic load capacity C		Determination of the dynamic load capacities and load moments is based on a 100 000 m travel as per DIN ISO 14728-1. Often only 50 000 m are actually stipulated. For comparison: Multiply values C, Mt and ML from the table by 1.26.
Dynamic torsional moment load capacity Mt footnote		Determination of the dynamic load capacities and load moments is based on a 100 000 m travel as per DIN ISO 14728-1. Often only 50 000 m are actually stipulated. For comparison: Multiply values C, Mt and ML from the table by 1.26.
Dynamic longitudinal moment load capacity ML footnote		Determination of the dynamic load capacities and load moments is based on a 100 000 m travel as per DIN ISO 14728-1. Often only 50 000 m are actually stipulated. For comparison: Multiply values C, Mt and ML from the table by 1.26.
