Deep Groove ball bearings can sustain radial, axial, or composite loads and because of simple design, this bearing type can be produced to provide both high-running accuracy and high-speed operation.
Standard ball retainers (cages) are made from pressed steel. Machined cages are used in bearing operating at very high speed or for large diameter bearings.
Deep groove ball bearings with seals or shields are standardized.
These bearings are pre greased for lifetime use, and will not require lubricating.
