WebIn the simplest terms, L10 life is calculating, with 90% reliability, how many hours a bearing will last under a given load and speed. There is a 10% probability that at the applied load … Web26. jul 2024. · Bearing life (L 10) can be calculated with the following formula. Variables required are basic dynamic load rating (C) and the dynamic equivalent load of the bearing (P). L10 = (C/P)3 L 10 = rating life (10 6 rev); C = basic dynamic load rating (lb or N); P = dynamic equivalent load (lb or N)
Web01. feb 2024. · The well-known bearing life equation, often referred to as L10 life, is a fundamental element in the sizing and selection of recirculating linear bearings. Through statistical analysis and real-world testing, the L10 life equation can predict, with 90 percent reliability, the life that a recirculating bearing can be expected to achieve.
