Question

A single-row, 02-series deep-groove ball bearing is to be used for the application shown in Figure 1.

The shaft is rotating at 1800 rpm and the bearing is intended for continuous operation for 15000

hours. The axial force is 1.75 kN. Determine the maximum radial load that can be applied to this

bearing without any failure during its life.

Explanation / Answer

sorry calculation mistake

L10 = (60NL10h)/ 10^6

= 162 million rev.

C= P(L10)^1/3= 9539.8 N
