Where heat is likely to be transmitted through a bearing
- group 2 bearings are used.
- group 4 bearings are used.
- group 3 bearings are used.
Explanation
Where heat is liable to pass through a bearing, the higher tolerance group (group 4) is specified so that thermal expansion does not reduce the running clearance below acceptable limits. A tighter group would risk the bearing seizing as the components grow with temperature.
EgiGol asking:

Bearing Clearance and Classification in "Bearings Chapter". Also the "DOT Method" is described there.
