Deep groove ball bearings are the most widely used bearing type and are suitable for many different industries. Matching the versatility of many different applications, they are available in a wide range of designs, variants and sizes. The following are examples of applications where deep groove ball bearings may be used.
Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.
DGBB can carry axial loads in both directions, whereas angular contact ball bearings can only carry axial loads in one direction.
Seals and shields provide additional protection for the bearing components and help to improve and maintain lubrication. In terms of sealing performance, sealed bearings rank best, followed by shielded bearings and finally open bearings.
