What type of bearing is designed to mount a shaft perpendicular to the mounting surface?

A flange bearing is specifically designed to mount a shaft perpendicular to the mounting surface. This type of bearing has a flange that allows it to be securely attached to a common mounting surface, providing support for the shaft while allowing for rotation. The perpendicular orientation is ideal in applications where space constraints or specific alignment is necessary for effective operation.

In contrast, sleeve bearings are typically used to support a shaft parallel to the mounting surface, featuring a cylindrical design that provides a smooth surface for the shaft to rotate within. Angular contact bearings are designed to manage loads in both axial and radial directions but do not specifically focus on perpendicular mounting. Thrust bearings are meant for handling axial loads and do not provide the support mechanics necessary for perpendicular shaft mounting. Therefore, a flange bearing is the most suitable choice for this application.
