1. A bearing housing comprising:
a cooling channel extending around a circumferential length of the bearing housing, the cooling channel being defined by a top surface and a bottom surface, the cooling channel comprising:
flow guide members configured to construct a tortuous passage, the flow guide members comprising a radial height being at least 50% but less than 100% of a height of the cooling channel as measured in a radial direction between the top surface and the bottom surface,
wherein the tortuous passage comprises a flow distance, the flow distance being longer than the circumferential length;
wherein the flow guide members are configured such that the tortuous passage extends substantially in a serpentine shape along the circumferential length.
 
2. A bearing housing comprising:
a cooling channel extending around a circumferential length of the bearing housing, the cooling channel being defined by a top surface and a bottom surface, the cooling channel comprising:
flow guide members configured to construct a tortuous passage, the flow guide members comprising a radial height being at least 50% but less than 100% of a height of the cooling channel as measured in a radial direction between the top surface and the bottom surface,
wherein the tortuous passage comprises a flow distance, the flow distance being longer than the circumferential length;
wherein the flow guide members are arranged at intervals along the circumferential length, so as to construct the tortuous passage through a distributed arrangement thereof.
 
7. A bearing housing unit comprising:
a bearing housing comprising a cooling channel, the cooling channel extending around a circumferential length of the bearing housing, the cooling channel being defined by a first axial side edge and a second axial side edge which both extend entirely circumferentially along the circumferential length;
a flow guide member being positioned between the first axial side edge and the second axial side edge and configured to construct a tortuous passage, wherein the tortuous passage comprises a flow distance being longer than the circumferential length, the tortuous passage abutting the first axial side edge and the second axial side edge; and
a rolling bearing being arranged in the bearing housing.
 
8. A continuous casting machine comprising:
a continuous casting roll line, the continuous casting roll line further comprising a bearing housing unit, the bearing housing unit comprising:
a bearing housing comprising a cooling channel extending around a circumferential length of the bearing housing, the cooling channel being defined by a first axial side edge and a second axial side edge which both extend entirely circumferentially along the circumferential length;
a flow guide member being positioned between the first axial side edge and the second axial side edge and configured to construct a tortuous passage, the tortuous passage abutting the first axial side edge and the second axial side edge, wherein the tortuous passage comprises a flow distance being longer than the circumferential length, and
a rolling bearing being arranged in the bearing housing.
