White Paper: The Facts About Roller Bearing Life Calculations
This in-depth white paper provides a detailed analytical approach to calculating life, and is designed to give engineers confidence when applying our broad range of linear motion solutions to their applications. This method applies to all products within the Cam Roller Technology (CRT) family including Redi-Rail, V-Guide wheel, Commercial Rail, and Hevi-Rail, along with Integral-V Technology (IVT).
All factors and formulas are based on data that has been proven over time by sources such as the International Organization for Standardization (ISO), as well as its membership bodies that include, but are not limited to, ANSI, DIN, and JISC.
It should be noted that there is no known formula for accurately and reliably calculating the actual lifetime of a linear or rotary bearing system. Even though these formulas are not absolutely certain, they have been generally accepted as the best available method for determining bearing lifetime by the ISO and its membership bodies.
