Single-row deep groove ball bearings are of non-separable construction. They are manufactured in multiple series and executions e.g., open, with single shield or Seal and double shield or Seal. These bearings are capable of silent running with low friction and are suitable even for high rpm. The rpm of Sealed bearings is limited in comparison with the open type.
The single-row deep groove ball bearings can transmit radial and axial forces in both directions at relatively high rpm thanks to relatively deep grooves and high degree of alignment between the rolling elements and the raceways. Only low misalignment of bearing rings is allowed for single-row deep groove ball bearings. The bearings are supplied with standard radial clearance and running accuracy . However, bearings with lower or higher radial clearance as well as higher running accuracy can also be supplied.
