The design load on a ball bearing is 413 lbf and an application factor of 1.2 is appro-
priate. The speed of the shaft is to be 300 rev/min, the life to be 30 kh with a reliability
of 0.99. What is the C10 catalog entry to be sought (or exceeded) when searching for a
deep-groove bearing in a manufacturer's catalog on the basis of 106 revolutions for rat-
ing life? The Weibull parameters are xo = 0.02, (0 – xo) = 4.439, and b = 1.483.

A Self-aligning medium series bearing for bores of 85 mm is operating at 300 r.p.m for an average life of 9 years at 10 hours per day, is acted by a 15 kN radial load and 10 kN thrust load. The bearing is subjected to a light shock load and the inner ring is sationary.
Determine the suitable self-aligning bearing. Mention the advantage of using self align bearing.
The design of journal bearings usually involves two suitable combinations of variables: variables
under control and dependent variables or performance factors. As such, a full journal bearing has
a shaft journal diameter of 27 mm with a unilateral tolerance of 20.01 mm. The bushing bore has
a diameter of 27.04 mm with a unilateral tolerance of 0.03 mm. The //d ratio is unity. The bushing
load is 1.03 kN, and the journal rotates at 1153 rev/min. You are required to analyze the minimum
clearance assembly if the average viscosity is 50 mPa.s to find the minimum oil film thickness,
the power loss, and the percentage of side flow.
