Deep groove ball bearings are widely used due to their versatility and affordability. They operate efficiently at high speeds and moderate loads, requiring minimal maintenance. These bearings can handle both radial and axial loads in both directions with minimal friction losses.
Maintaining slight misalignment between the outer and inner rings, even with increased bearing clearance, ensures optimal performance. Mounting them on hard double-seat shafts prevents excessive misalignment caused by external forces.
Available with metal shields or various seals, deep groove ball bearings are suitable for diverse applications where additional sealing devices may be impractical. While pressed steel cages are common, newer models feature more durable cages made of glass fiber-reinforced polyamide, offering benefits like higher speed and reduced noise. Specialized or larger bearings may utilize cages made of brass, aluminum alloys, or other materials.
