Ball bearings can be calssfied as “open”,”shielded”,”sealed”.

(1)   Single-row deep groove ball bearings

They can sustain radial loads mainly and can also sustain some axial load in either direction.The bearings have low friction and very little noise or vibration,These Characteristics make them to be available for situations of high speed,high pricision ,low friction and low noise operations.

(2)   Shielded and sealed bearings

Deep groove ball bearings often have shields or seals installed on both sides and are factory-packed with a lubricant.The use of such bearings simplifies the structure of installation.It also eliminates the need for relubrication and,there for,reduces maintenance costs.

There are three types of such closed bearings:shielded bearings,contact sealed bearings,and noncontact sealed boarings .
