Properties

BallBearingWeibullReliabilitySlope

Used in the calculation of the a1 factor for modified bearing life in ISO 281:2007 and ISO/TS 16281:2008. The default value is 1.5, which according to ISO/TR 1281-2:2008(E) should be used for probabilities of failure less than 10%.

Type Description
System.Double

IncludeExponentAndReductionFactorsInISOTS162812008

The basic dynamic load rating 'Cr' defined in ISO 281:2007 includes a reduction factor λ to account for stress concentration and a factor ν to account for a single exponent used in the life formula. In ISO/TS 16281:2008 the detailed stress distribution is calculated for the bearing elements, so these factors are not required. In equations 47, 48, 50 and 51 of ISO/TS 16281:2008 the basic dynamic load is divided by the 2 factors to cancel them out of the basic dynamic load rating. If you have specified basic dynamic load ratings for bearings that do not include the 2 factors then this option can be used to not cancel them in the ISO/TS 16281:2008 calculations.
