Bearing pressure calculator

The Bearing pressure calculator computes bearing pressure from the relation P = F / (d L). It takes 3 inputs (radial load in N, bearing diameter in m, bearing length in m) and returns the bearing pressure in Pa. Because this is a pure mathematical or physical formula rather than a jurisdiction-specific rule, the result never changes over time: the same inputs always produce the same answer, so you can rely on it whether you are checking homework, sizing a design, or sanity-checking another tool. Enter your values in the fields below and the result updates instantly; you can also share a permalink that pre-fills the exact calculation, which is useful for teaching, reports, or collaboration. For example, with radial load = 100 N, bearing diameter = 1 m, bearing length = 1 m, the bearing pressure works out to 100 Pa, and the worked example further down the page shows every step so you can follow the arithmetic and reproduce it by hand. The method is the standard form documented by Documented methodology, and the figure above each result carries the date it was last verified.
