Deep groove ball bearings
1) Structure andCharacteristics
A widely used bearing, the
deep groove ball bearing takes its name from the formed on both the inner and ourer rings of thebearing. The bearings can sustain radial and axial loads and the resultantforces of these loads and they are suitable for high speedoperation.
The dimensional table below represents thevarious cage models and specialshapes.Drawing A is the pressed cage;drawing Bshows the machined cage;drawingsC through F show the position and shape of thenotch on the inner ring;anddrawing G shows a bearing with the key groove on themachined cages are used forlarger sized bearings, or bearings for high speedrotation.
Except open bearings,most bearings manufactured by our company have shieldsorseals installed in both sides and are packed with a lubricant.Such bearingscansimplify the structure around them and also their installation. Italsoeliminates the needs for relubricaton. Therefore, it reducesmaintenancecost.

2) 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).
