Introduction to Single Row Cylindrical Roller Bearings

Single row cylindrical roller bearings serve as a crucial component in various machinery applications, significantly contributing to operational efficiency. Their design allows them to handle both radial and axial loads while maintaining minimal friction. This article explores the intricacies of these bearings, detailing their importance in industrial settings and the benefits they offer to machinery performance.

Design and Structure of Single Row Cylindrical Roller Bearings

Single row cylindrical roller bearings consist of cylindrical rollers that are arranged in a single row. This design facilitates a larger contact area between the rollers and the raceway, which enhances load distribution. The components typically include:

Components of Single Row Cylindrical Roller Bearings

• Inner Ring: The inner ring is mounted directly onto the shaft, providing stability and support.


• Outer Ring: The outer ring houses the rollers and fits snugly within the bearing housing.


• Cylindrical Rollers: These are designed to reduce friction and increase load-carrying capacity.


• Cage: The cage keeps the rollers evenly spaced, preventing them from coming into contact with each other.

Types of Single Row Cylindrical Roller Bearings

While there are various types of cylindrical roller bearings, single row variants are preferred for their simplicity and effectiveness. They can be categorized into:

• NU Type: Features a cylindrical bore and can accommodate axial displacement.


• N Type: Similar to NU but with an additional flange on one side, allowing for axial load support.


• NJ Type: Combines the features of NU and N types, providing enhanced axial load handling.
