This selection calculation sheet determines the tangential load of the load using general formulae. Based on the tangential load of the load and the designated operation type,
it will use the selection method shown in he pin gear drive unit catalog and display the selection results.
Please decide whether the load calculations are appropriate in light of the characteristics of the equipment you are using.
