Service Life | If selected Adams Machinery will calculate a service life prediction at every output step which can be interpreted as the predicted service life in hours for the bearing under the loading and rotational speed conditions at the given time step. This KISSsoft-driven calculation is based upon ISO/TS 16281. For more details see sections Calculation of service life based on the bearing inner geometry (ISO/TS 16281) and Bearing Service Life. | |
Lubricant Properties: The main function of the lubricant is to separate the active surfaces of the bearing by maintaining a film of oil between the rolling elements and their raceways in order to avoid wear and limit abnormal stresses and heating in the metal-on-metal contact area. For more details see sections Calculation of service life based on the bearing inner geometry (ISO/TS 16281) and Lubrication. The lubricant also have the following functions: ■Cooling the bearing when the lubricant is oil ■Preventing oxidation | ||
Lubricant Type | Select if the lubricant in an oil or grease type (this will filter the Lubricant option menu). | |
Lubricant Manufacturer | Select the lubricant manufacturer (this will filter the Lubricant option menu). | |
Lubricant | Select the lubricant to be assumed for the service life prediction. | |
Lubricant Temperature | Select the lubricant temperature to be assumed for the service life prediction. The value entered for the lubricant temperature is only used to calculate the extended working life of the bearing. The lubricant temperature changes the lubricant's viscosity. | |
Failure Probability | Enter the failure probability to be used for the service life prediction. This equates to the percentage of bearings that can be expected to fail after the calculated service life duration due to classical fatigue failure. The maximum failure probability for which service life can be calculated is 10%. This is a constraint of the life prediction method used. The service life calculation is only influenced by the failure probability values shown below. Entries in this field will be rounded to the nearest value in the table below during calculation. See section Calculation of service life based on the bearing inner geometry (ISO/TS 16281) for more details on the usage of the life modification factor, a1. | |
