ABSTRACT:
A ceramic and masonry power saw is constructed with a fluid cooling bearing assembly to drive a saw blade. The fluid cooling bearing assembly includes a bearing housing which has a coolant chamber embracing around the shaft sleeve. The coolant chamber has a C-shaped cross section and is extended along the shaft sleeve. The bearing housing also provides a coolant inlet and a coolant outlet for sealedly connecting the coolant chamber with the coolant conduit arrangement. Therefore, the coolant would not only be pumped to cool the saw blade and the work piece to be cut, but also be pumped to flow inside the bearing housing for cooling the rotating blade shaft in order to prevent overheating of the blade shaft.
