A bearing has spacers 40 (70 fig 4) to separate adjacent bearing balls 36 (14 fig 4) in a race defined by inner 54 (26 fig 1) and outer 64 (20 fig 1) bearing surfaces. The spacers may extend radially outwardly of a radially inwardly extending circumferential rib 42 of the outer bearing surface 64. With the spacers held completely between the inner and outer bearing surfaces (and not between the circumferential rib 42 and inner bearing surface 54), the outer bearing surface 64 can be kept large to accommodate for larger loads than with a bearing having a conventional cage for the balls. Preferably, the spacers compliment the shape of the balls and are seated on the inner and outer bearing surfaces. The spacers may be used in a single race ball bearing or the circumferential rib may define two outer bearing surfaces 64, 66 in a double race bearing. |
