Needle roller bearings without inner ring are directly mounted
on the shaft using it as rolling groove, the shaft must be
hardened and grinded and it has to keep the same hardness of
needle rollers.
This enables to better utilise the bearings concerning load
ability, number of revolutions reached and duration.
