What is a bearing surface that completely surrounds the journal also known as?

A bearing surface that completely surrounds the journal is referred to as a full bearing. This design allows for uniform distribution of load over the entire bearing surface, which helps to reduce wear and increase the longevity of both the bearing and the journal it supports. Full bearings facilitate smoother operation by offering a more consistent contact area, minimizing the chances of localized stress concentrations, and providing better support for axial and radial loads.

This type of bearing is crucial in applications where the alignment of loads is essential for optimal performance. It allows for better lubrication opportunities, as the full surface can maintain a proper lubricating film, contributing to reduced friction and heat generation in the system. By wrapping around the journal completely, full bearings ensure stability and durability, making them a popular choice in machinery design and applications.
