Question

Select a single row, deep-groove ball bearing to carry a radial load of 300 lb and a thrust load of 200 lb. The outer race is rotating at a speed of 350 rpm, and a design life of 40000 hr is desired. A bearing with a basic dynamic load rating of 7500 lb and a basic static load rating of 5850 lb is proposed. Will it work? solve it in details, thank you.

Answer #1

Suppose a deep-groove ball bearing with a catalog load rating of
35.1 kN is to run at 1,785 rpm. The replacement interval for the
bearing must be at least 7,060 hours. It is satisfactory to design
for 90 percent reliability in this case.
Determine the maximum permissible radial load in kN.

Question # 3 Part A. An 02-series ball bearing is to
be selected to carry a radial load of 8 kN and a thrust load of 4
kN. The desired life LD is to be 5000 h with an inner-ring rotation
rate of 900 rev/min. What is the basic load rating that should be
used in selecting a bearing of a reliability goal of 0.80? Is it a
safe decision?
