Deep Groove Bearing Advantages, Types and Buying Tips

Among other types of Ball Bearing , the Deep Groove Ball Bearing is the most common and consists of an outer, inner ring with steel balls and cages. These are used as radial bearings and has the ability to operate at very high speeds.

Deep groove bearings are actually a non separable bearings that can carry axial loads in both the directions. It consists of uninterrupted raceways that are also deep. The ring grooves are in the form of circular arcs that have radius more than that of the radius of the ball. Height of inner ring shoulders is equal to outer ring shoulders. Contact of the ball with raceways is point and elliptical when loaded.

Buying Tips

Before buying deep groove ball bearing check out the material from which it has been made. It can be chrome steel or high temperature steel. Then know what is the maintenance requirement and the service life. This will help you in defining the overall cost of the bearing. If every thing is low then the overall cost is also low. Ask for bearing clearance and sealing efficiency.

Types of Deep Groove Bearings

  • Sealed
  • Low Friction
  • Small Shielded
  • Large Shielded

Sealed ones are made from the synthetic rubber and oil with the sheet steel reinforcement. These can operate in wide range of temperature i.e. between -40กใ C to 120กใ C.

Low friction seal types can also operate between the same temperature range as the sealed ones. It is the kind of non-rubbing bearing as the a narrow gap is formed by the lip of the seal with the land of inner ring.

Small shielded ones have a sheet steel shield making a long sealing gap.

Large shielded has no cylindrical section and preferred when the rotation of the inner ring is required.

Deep Groove Bearing Advantages

These can carry extra load in the form of radial, composite and axial load.

These are very simple in design and need minimum maintenance.

The service life is longer than other types of bearings. Deep groove bearing needs less lubrication.

Low cost.
