Bearing breakdown: single row deep groove bearings

By Christine Berlly

The most widely used roller bearing type in the world due to their versatility and overall performance, single row deep groove ball bearings are characterized by having deep raceway grooves. The inner and outer rings have circular arcs of slightly larger radius than that of the balls. and they have non-separable rings.

Their straight forward basic design has many advantanges:

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 maintenance

As flexible as the performance is, the configurations of single row ball bearings is also as versatile. These bearings often have steel shields or rubber seals installed on one or both sides and are pre-lubricated with grease. Also, snap rings are sometimes used on the outside edge. While many different retainers are available, pressed steel cages are most commonly used. Even tapered bores are available upon special order.

Single row deep groove ball bearings come in three numerical series representing the size and load capacity of each. They are:

6000 Series – Extra Light Ball Bearings – suitable for limited space applications
6200 Series – Light Series Ball Bearings – Balanced between space and load capacity
6300 Series – Medium Series Ball Bearings –suitable for heavier load capacity applications
