NSK double row deep groove ball bearings

What is the difference between NSK single and double row deep groove ball bearings?

RHP double row deep groove ball bearings have all the features of their single row relative, along with an enhanced load carrying capacity thanks to the extra row of rolling elements.

These bearings are slightly wider than single row deep groove ball bearings, so require more axial space. However, the load carrying capacity is considerably higher, making these bearings an ideal choice for high speed applications with a moderate load requirement.
