2) Dimension H₂ without cover strip
3) Load ratings and load moments for ball runner block without ball chain. Load ratings and load moments for ball runner block with ball chain Page.12
Determination of the dynamic load capacities and load moments is based on a stroke travel of 100,000 m according to DIN ISO 14728-1.
Often only 50,000 m are actually stipulated. For comparison: Multiply the values C, M_t and M_L by 1.26 according to the table.
