BALL BEARING

A ball bearing wherein first and second annular clearances (delta1, delta2) are formed between the outer peripheral surface (20e) of the annular section (20b) of a cage (20) and the inner peripheral surface (11f) of the annular piece (11e) of a first outer ring member (11) and between the inner peri...

Summary:A ball bearing wherein first and second annular clearances (delta1, delta2) are formed between the outer peripheral surface (20e) of the annular section (20b) of a cage (20) and the inner peripheral surface (11f) of the annular piece (11e) of a first outer ring member (11) and between the inner peripheral surface (20f) of a baffle piece (20c) and the outer peripheral surface (13f) of the shoulder (13h) of a first inner ring member (13), respectively, and their radial widths (d1, d2) are set greater than 0 but not more than 0.15 times the diameter of balls (17, 18). Cette invention se rapporte à un roulement à billes, dans lequel des premier et second espaces libres annulaires ( delta 1, delta 2) sont formés entre la surface périphérique externe (20e) de la section annulaire (20b) d'une cage (20) et la surface périphérique interne (11f) de la pièce annulaire (11e) d'une première bague externe (11) et entre la surface périphérique interne (20f) d'une chicane (20c) et la surface périphérique externe (13f) de l'épaulement (13h) d'une première bague interne (13), respectivement, et dans lequel les largeurs radiales (d1, d2) de ceux-ci sont réglées supérieures à 0 mais inférieures à 0,15 fois le diamètre des billes (17,18).
