BALL RETAINING CAGE FOR BEARINGS AND A DEEP GROOVE BALL BEARING |
摘要 |
A cage for a ball bearing unit comprises two half-cages (51, 52) which are connected to each other and are symmetrical about a mid-plane (P) of the bearing. Each half-cage has an annular body (53) providing two concentric and circumferentially continuous radial ridges (56, 57) extending radially in opposite directions, of which the first ridge (56) extends in a radially outward direction for sealingly engaging a groove (25) formed in the outer ring of the bearing unit, and the second ridge (57) extends in a radially inward direction for sealingly engaging a groove (35) formed in the inner ring of the bearing unit.
