Types of Bearings | Uses & Working Mechanisms Explained

Aug 25, 2020· Ball bearings provide very low friction during rolling but have limited load-carrying capacity. This is because of the small area of contact between the balls and the races. They can support axial loads in two directions besides radial loads. Ball bearings are used for controlling oscillatory and rotational motion.

What types of bearing are very low friction?

What makes a bearing low friction? Bearings are designed to limit friction between moving parts. The rings and balls of these bearings are machined to fine tolerances and high levels of roundness to assist in the reduction of friction. Due to this specific design, turning resistance of bearings can be extremely low.
