The important factor to be considered while selecting a bearing is Correct Answer All option is correct

Concept:

Important factors to be considered:

  • Dimensional limitation: Allowable space for bearings is generally limited.
  • Applied loads: The characteristic, magnitudes & direction of loads is important.
  • Rotational speed: It depends upon bearing type, size, tolerance, cage type, load lubrication & cooling condition,
  • Bearing tolerances
  • Rigidity
  • Misalignment of inner & outer races
  • Noise & torque levels
  • Installation of disassembly.

Statement (I): The journal while rotating inside a bearing automatically shifts its centre to one side and thus the journal is eccentric inside the bearing. Statement (II): The wedge shape of oil film gives rise to thin-film lubrication, which is considered as stable lubrication.
If p = bearing pressure on projected bearing area, Z = absolute viscosity of lubricant and N = speed of journal, then the bearing characteristic number is given by
