Roller bearings (also known as roller element bearings) are similar in profile to ball bearings but rather than using balls to rotate they utilise cylinder rolling elements. Roller bearings carry a load by placing rolling elements such as rollers between outer rings and inner rings called races. This allows the bearing to maintain separation between moving parts, helping to reduce rotational friction and noise. For applications requiring high radial and axial load support, roller bearings are ideal and are available in a variety of designs and shapes.
Roller bearings are categorised by the shape of the roller which can reduce friction and support radial and axial loads. RS Components have a great range of bearings including tapered roller bearings and needle roller bearings to meet all your requirements. These types of bearings can feature single or multiple rows of rolling elements (which can increase radial load capacity).
There are a wide range of roller bearing available in various sizes and types, each suited to specific applications. Popular types of roller bearings include:
Rotary bearings have rollers to separate the races which improves load distribution and are designed to be used in a wide range of machine motion systems to ensure continuous low friction movement. Cylindrical bearings are designed to handle heavier loads than ball bearings. They can be used for various environments such as heavy machinery, manufacturing, aerospace and are often found in:
