  Deep groove ball bearings are the most common type of rolling bearings.
  The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a set of retaining structures.

Open type refers to bearings without a sealed structure, while sealed deep groove balls are divided into dust-proof and oil proof seals.
