Abstract

PURPOSE: To smooth the shaft rotation in the high speed range and prolong the life of a bearing device of machine tool etc. by giving a specific correlation between the diameter of bearing metal, the diameter of extra-hard alloy fixed to the ends of said bearing metal's inside surface, and the diameter of bearing collar.
CONSTITUTION: Extra-hard alloys 4, 4' are pressure-fitted or brazed at the ends of the inside surface 3 of a bearing metal 2, where the inner diameter d1 of the extra- hard alloys 4, 4' shall be related to the inner diameter d2 of the bearing metal 2 as d1<d2 to form a gap 5 between, and at least one of oil grooves 7, 7' is excavated in the extra-hard alloys 4, 4'. On the outside surface of the ends of collar 8, extra- hard alloys 12, 12' are pressure-fitted or brazed to form a bearing collar 11, where the outside diameter D1 of the extra-hard alloys 12, 12' shall be related to the outside diameter D2 of the collar 8 as D1>D2 to form a bearing collar 11'. The bearing metal 2 is fitted on the collar 8, bearing collar 11 or 11' fixed to cutter arbor 9. Thus a good lubrication is secured.
