cylindricalroller

A cylindrical roller is a type of rolling-element bearing that uses cylindrical rollers as rolling elements instead of balls. These bearings are designed to support heavy radial loads and are known for their high load-carrying capacity. The rollers are typically longer than they are wide, and their cylindrical shape allows for a larger contact area with the bearing races compared to ball bearings. This larger contact area distributes the load over a greater surface, reducing stress and increasing the bearing's durability under heavy loads.

Cylindrical roller bearings are available in various configurations, including single-row, double-row, and multi-row designs, each offering different load capacities and stiffness. They can also come with different cage designs, which help to separate and guide the rollers. Some designs incorporate features like separable inner or outer rings, which can simplify installation and maintenance. The absence of shoulders on one of the races in certain designs allows the bearing's inner and outer rings to move axially relative to each other, providing limited axial displacement capability.

Due to their high radial load capacity, cylindrical roller bearings are commonly used in applications such as heavy machinery, industrial gearboxes, electric motors, and railway axle applications where substantial radial forces are expected. Their ability to handle shock loads and operate at high speeds also makes them suitable for demanding industrial environments.
