*4.3.2 Power dense solutions*

Power dense solutions related to more load carrying capacity per unit bearing size. As mentioned in the last sections, the bearings are catalysts to achieve a lower weight of the aggregate. Weight is the enemy for vehicle performance particularly in electric vehicles as it directly influences range as well as battery capacity. Lower size of bearings accumulates lesser space as well is makes the aggregate system compact. An additional advantage of power-dense bearing it utilizes lesser material, so it is also another means of achieving environmentally friendly solutions.

Current bearing material development and steel cleanliness is increase material mechanical properties. Additionally, manufacturing technologies increased control over the tolerances are enabling the power dense solution. Typically, 20 to 30% higher load carrying capacity can be improved within same envelope of bearings with right selection of material, geometries and manufacturing process including heat treatment.
