BORES AND THREADS
The inner ring bore is ground and polished, the tolerance is H7.
Its diameter is the nominal measure of the type and the basis for all other dimensions.
The rod thread, tolerance 6h, is available in several versions.
The loads are expressed in daN.
They indicate the maximum static load before permanent deformation of the body.
The maximum unidirectional dynamic load is not more than 50% of the given static loads.
For alternating dynamic loads, the limit is 25%.
