Bearing temperature raise

  1. Mar 19, 2008 #1
    Dear all
    I need to calculate bearing Temperature for the shaft rotating of certain rpm.
    Bearing catalog referred and found that cooling factor is missing to arrive final result.
    How to find cooling factor?any empherical procedures?standards?sites? If so pl guide me to get the result.

    That information is almost always an empirical number derived from manufacturer testing. You would need to contact the bearing manufacturer because it will depend on things like loading, lubrication and mounting fits.

    Thanks Mr.Fredgarvin

    Ok have you any idea to convert the power loss (due to friction)to temperature.
    i.e.assume that 10 watts power is loss what will be the corresponding temperature induced (without accounting lubrication factor i.e.cooling factor)

    thanks in advance
