Basic Load The load carrying capability of a bearing is determined by calculation of the bearing pressure a force exerts on the surface area of the bearing point. Due to the complex force distribution involved, it is normally convenient to calcualte the forces under the assumption that the radial force (F) is acting on a bearing point which has a surface area equal to the bushing ID times the bushing length.
With a force (F), a supported bearing length (l-f) and a tension bushing ID (di), the average surface pressure may be calculated as follows:
The results calculated as set forth must be compared to allowable loads for the system. For a system at rest, designers must assure a sufficient safety margin as compared to the compression yield point of the bearing material. Under dynamic loads, validation of the safety margin must include consideration of the material's fatigue limits as well as stress boundaries.
