Problem 5.2: An angular-contact, inner ring rotating, 02-series ball bearing is required for an application in which the life requirement is 40 kh at 520 rev/min. The design radial load is 725 lbf. The application factor is 1.4. The reliability goal is 0.90. Find the rating life X required and the catalog rating C10 from Table 11–2. Choose a bearing and estimate the existing reliability in service.

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 Lp 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 for a reliability goal of 0.90? Hints: Rating life is 1(10°) revolutions, Weibull parameters of rating lives are x, = 0.02,0 = 4.459, b = 1.483 respectively.

A certain application requires a ball bearing with the inner ring rotating, with a design life of 26 kh at a speed of 455 rev/min. The radial load is 2.5 kN and an application factor of 1.2 is appropriate. The reliability goal is 0.92. Find the multiple of rating life required, xD , and the catalog rating C10 with which to enter a bearing table. Choose a 02-series deep-groove ball bearing from Table 11–2 and estimate the reliability in use.

A certain application requires a ball bearing with the inner ring rotating, with a design life of LD = 15 kh at a speed of nD = 480 rev/min. The radial load is Fr = 1.4 kN, the axial load Fa = 0.4 kN, and an application factor of af = 1.2 is appropriate. The reliability goal, R = 0.99. a) Determine the multiple of rating life required, xD, and the catalog rating C10FR, where FR is the calculated bearing load in [kN] with which we enter a bearing table. Specify a 02-series angular contact ball bearing from Table 11–2,    b) Estimate the reliability (R) and multiple of rating-life (XD) in use.

Answer this ASAP plz A double row angular contact ball bearing is used in the engine compressor to accept radial loads of 6000 N and axial loads of 3000 N, operating at 2400 rpm for an average life of 7 years at 8 hours per day. Assume that the shock load is light. Select the appropriate bearing number. Note: the equivalent dynamic load is the dynamic equivalent radial load times the service factor.

A set of sleeve bearings has a specification of shaft journal diameter of 31.25 mm with a unilateral tolerance of -0.025 mm. The bushing bore has a diameter of 31.3 mm with a uni- lateral tolerance of 0.075 mm. The bushing is 31.25 mm in long. The radial load is 1113N and the shaft rotational speed is 1750 rev/min. The lubricant is SAE 10 oil and the axial-groove sump temperature at steady state T, is 49°C. For the cmin, Cmediany and Cmax assemblies analyze the bearings and observe the changes in S, e, f, Q, Q, AT, Tmax, Tr, and h.

Select an angular contact ball bearing to carry a radial load of 336lb at a shaft speed of 1800 rpm for 5500 hours. Anapplicationfactorof1.2isappropriate. Use a reliability of 96%.

A 02-series single-row deep-groove ball bearing is to be selected from Table 11-2 for the application conditions specified in the table. Assume Table 11–1 is applicable if needed. The value of radial load Fr= 8 kN, axial load Fa= 3 kN, design life LD = 10°, ring rotation factor V= 1.2, and reliability RD= 0.95. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the C10 value for this application. The C10 value for this application is kN.
