Single row deep groove ball bearing
Structure and Characteristics
A widely used bearing, the deep groove ball bearing takes its name from the formed on both the inner and
ourer rings of the bearing. The bearings can sustain radial and axial loads and the resultant forces of
these loads and they are suitable for high speed operation.
The dimensional table below represents the various cage models and special shapes.Drawing A is the pressed
cage;drawing B shows the machined cage;drawings C through F show the position and shape of the notch on the
inner ring;and drawing G shows a bearing with the key groove on the machined cages are used for larger
sized bearings, or bearings for high speed rotation.

Materials for rings and rolling elements
While the contact surfaces between the bearing rings and rolling elements are subjected to repeated heavy stress,they must still maintain high rotational precission, therefore, the materials used for bearings rings and rolling elements require the following characteristics:
● High rolling contact fatigue strength
● High hardness
● High wear resistance
● High dimensional stability
● High mechanical strength
The material used by our company is high carbon chromium bearings steel GCr15-GB/T18254 equivalent such as AISI 52100(USA), DIN 100Cr6(Germany) JIS SUJ2(Japan) and BS 534A99 (UK).
