- Problem 2 A 02-series single-row deep-groove ball bearing with a 65-mm bore (see Tables 11–1 and 11– 2 for specifications) is loaded with a 10-kN axial load and a 15-kN radial load. The inner ring rotates at 500 rev/min. (a) Determine the equivalent radial load that will be experienced by this bearing. (b) Determine whether this bearing should be expected to carry this load with a 95 percent reliability for 20 kh.arrow_forwardThory of machine: Select one of the following bearing for the load conditions. Radial load, F=3000 N, Axial load, F = 1600 N, RPM = 1000.

Assume that the shock load is light. Select the appropriate bearing number.

The inner ring rotates at 600 rpm (v=1). What is the FaC0? Should X1/Y1 or X2/Y2 be used to caculate the equivalent radial load? Determine the equivalent radial load experienced by this bearing. What is the bearing’s in-use reliability, assuming a design life of 2*10^8 revolutions and an application factor of 1.2?arrow_forwardA certain application requires a ball bearing with the inner ring rotating, with a design life of 25 kh at a speed of 400 rev/min. The radial load is 3.5 kN and an application factor of 1.5 is appropriate. The reliability goal is 0.90. Find the multiple of rating life required, Xp 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.arrow_forward

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.arrow_forward
