Deep Groove Ball Bearings

Deep Groove Ball Bearings are the most common and widely used bearing type and they are very popular due to their versatility and overall performance.

They are characterised by having deep raceway grooves in which the inner and outer rings have circular arcs of a slightly larger radius than that of the balls. They have non-separable rings and their straight forward basic design has many advantanges for a high proportion of applications.

Typically the main benefits of a deep groove ball bearing are;

  • Excellent for high speeds
  • Good radial load capacity
  • Acceptable axial load capacity in both directions
  • Have low torque capacity at startup and running speeds
  • Can operate with low noise
  • Require little or no maintenance


The bearings can be supplied open or have have steel shields or rubber seals installed on one or both sides and are pre-lubricated with grease. In addition they can be supplied with snap rings to facilitate location as well as a range of tolerances, fits, cage types and even tapered bores or spherical outside diameters. They are available as single row, double row in various cage types and materials for light, medium and heavy duty applications.
