An Overview of Cylindrical Roller Bearings and Their Intended Applications

June 25, 2021

Machines are typically comprised of elements that allow them to work optimally. One of the elements that can be found in a lot of machines is bearing. A bearing is a hardware element that can restrict the relative motion of a machine to solely its desired motion. It is likewise designed to support the rotating shaft inside the machine and minimise the friction between its moving parts.

Even though bearings can be grouped into various types, they all boast the same core functionalities that can be useful for different industries. The main difference among them is that they work on varying principles. One known type of bearing is the cylindrical roller bearing.

Design of Cylindrical Roller Bearings

Cylindrical roller bearings mainly utilise cylinders as their rolling element, as opposed to balls and other similar components. The cylinders of these bearings separate their inner and outer rings, allowing them to reduce the overall frictional force between both rings. Typically, the number of cylinders that a cylindrical roller bearing possesses may vary. But given the capability of the cylinders, bearings that possess a high quantity of these components usually gain significant performance improvements.

These bearings can be generated out of many materials. Some of these materials include alloy steel and pressed steel. These materials often provide bearings with the needed durability and longevity for them to work optimally.

But apart from these materials, cylindrical roller bearings can also be created out of sintered metal. Bearings made from sintered metal often possess notable strength, electrical conductivity, thermal conductivity, and reduced porosity. Those made from sintered metal are often utilised by many industries due to their aforementioned qualities.

Cylindrical Roller Bearing Variations

The general design and materials of cylindrical roller bearings allow them to possess a greater radial load capacity. They can likewise sustain faster speeds compared to other bearing types.

Cylindrical roller bearings can be further grouped into three variations. These variations include single row cylindrical roller bearings, double row cylindrical roller bearings, and multi-row cylindrical bearings. Single row cylindrical roller bearings possess a single set of an inner and outer ring and a single set of rollers and a cage. These bearings are separable, allowing them to be mounted and dismounted easily.

Double row ones, alternatively, possess two sets of rings, rollers, and a cage. They are used in precision machines due to their remarkable accuracy, carrying capacity, and augmented strength. Ultimately, multi-row cylindrical bearings feature high carrying capacity with reduced performance. Both double row and multi-row cylindrical roller bearings can offer better radial load capacity than the single row ones. They can likewise transfer axial loads in a single direction.

Notable Applications of the Bearing

The radial load capacity of the cylindrical roller bearings as well as their fast speeds allow them to be utilised in a lot of machines. Some of these machines include gearboxes, wind turbines, electric motors, pumps, steel mills, motorcycles, railways, and machine tools.
