  • How to calculate linear bearing life

    2014-10-30 · Equations for calculating linear-bearing life. To begin, we’ll set up the bearing life equations for 50,000 m service life and 100,000 m service life: L = service life C = dynamic load capacity F = applied force. Setting the life equations equal to each other allows us to begin deriving the ratio of C 50 to C 100:
