The needle roller bearing is suitable for both grease and oil lubrication. Ensuring the correct type of lubrication will maintain performance and longevity, particularly at high speeds.

The single-row design allows for efficient load distribution, making it capable of handling both dynamic and static loads effectively. This enhances its suitability for various demanding applications.

The fatigue limit load of 5,400N indicates the maximum load the bearing can endure over time without incurring fatigue failure. This rating ensures longevity and reliability in demanding environments.

The standard sheet steel cage offers a balance between strength and weight, promoting effective load handling while minimising mass. This is crucial in applications where reducing weight is necessary without sacrificing performance.

The open end design facilitates easier access for lubrication, which is essential for maintaining optimal performance over time, especially in high-speed applications.
