Cylindrical roller bearings are a type of rolling-element bearing that uses cylinders instead of balls as the rolling element. This design provides several benefits such as increased radial load capacity, higher tolerance to shock loads, and longer service life. Cylindrical roller bearings are used in a variety of applications including automotive, aerospace, construction, and industrial equipment. In this article, we will explore what cylindrical roller bearings are, their key features, and how they can be used in various applications.
