Which of the following is not the part of roller bearing?
In a journal bearing P = average bearing pressure, Z = absolute viscosity of the lubricant, N = rotational speed of the journal. The bearing characteristic number is given by
With a dynamic load capacity of 2.2 kN, a roller bearing can operate at 600 rpm for 2000 hours. Then its maximum radial load will be equal to
A sliding bearing that can support steady loads without any relative motion between the journal and the bearing is called as
The expected life of a ball bearing subjected to a load of 9800 N and working at 1000 rpm is 3000 hours. Then the expected life of the same bearing for a similar load of 4900 N and speed of 2000 rpm will be
The dynamic load capacity of 6306 bearing is 22 kN. The maximum radial load it can sustain to operate at 600 rev/min, for 2000 hours will be equal to
Which of the following assumptions regarding the lubricant film is made in Petroff’s equation?
