Dimensions and Ratings r Wr r r R R C F H A C D F B X V R Z U DIMENSIONS The basic boundary dimensions (bore, outside diameter, width) in the following tables conform to the standards established by ABMA/ANSI. A description of dimensions represented by various letters is given below: B Maximum bearing bore diameter. The minus tolerance is given on page 79 76 and the range in “Fitting Practice” section D Maximum bearing O.D. The minus tolerance is given on page 79 76 and the range in “Fitting Practice” section W Maximum bearing width. The minus tolerance is given on page 79. 76 A Maximum O.D. of the inner ring raceway X V Z U Recommended maximum housing shoulder diameter for plain outer rings Recommended minimum shaft shoulder diameter for ribbed inner rings Recommended maximum housing shoulder diameter for ribbed outer rings Recommended minimum shaft shoulder diameter for plain inner rings Dimensions shown in tables are given in both inch and metric units and are based on: 1 inch = 25.4 mm exactly 1 micrometer = 1m = 10 -6 m 1 micrometer = .001 mm C F H R r Minimum I.D. of the outer ring raceway Maximum rib O.D. of the inner ring Minimum rib I.D. of the outer ring Maximum fillet on the shaft that the bearing corner will clear Maximum fillet in the housing that the bearing corner will clear LOAD RATINGS The radial load ratings this in this catalog catalog are based are based on 3000 on hrs 500 L10 hrs life L 10 at life 500 at rpm 33 1 ⁄3 or rpm 90 million or 1 million cycles cycles for either for inner either orinner outeror ringouter rotation. ring To rotation. convert this To convert rating to 500 this hrs rating L10to life 3000 at 33- hrs 1 /3 L 10 rpm life at or 500 1 million rpm cycles or 90 million basis, multiply cycles basis, by 3.857. divide by 3.857.
