  • Ball Bearings - SDP/SI

    Life adjustment factors allow the original equipment manufacturer to better predict the actual service lives and reliability of bearings that you select and install in your equipment. An adjusted calculated L 10 rating life is calculated by using the following formula: Lna = a1 x a2 x a3 x L10. where: Lna = adjusted rating life
