What is EN ISO 8459-1:2012?


EN ISO 8459-1:2012 is a technical standard that provides guidelines for the determination of static and dynamic characteristics of linear tapered roller bearings. This standard, published by the International Organization for Standardization (ISO), plays a crucial role in ensuring the reliability and performance of these types of bearings.

Static Characteristics Testing

Static characteristics testing is an essential part of evaluating the performance of linear tapered roller bearings. This includes measurements of load capacity, stiffness, friction torque, and wear. By subjecting the bearings to various loads and analyzing their response, engineers can assess their ability to withstand static forces and maintain their integrity over time.

One of the key objectives of EN ISO 8459-1:2012 is to provide standardized testing methods for these static characteristics. By establishing a common procedure, this standard enables reliable and comparable results across different manufacturers and applications. It helps ensure that end-users receive quality products that meet their specific requirements.

Dynamic Characteristics Testing

In addition to static characteristics, the dynamic performance of linear tapered roller bearings is crucial for their proper functioning in real-world applications. Dynamic characteristics testing involves measuring parameters like rotational speed, natural frequency, damping ratio, and resonance behavior.

EN ISO 8459-1:2012 specifies the test conditions and procedures for evaluating the dynamic characteristics of these bearings. It ensures accurate measurements of factors that affect their vibration and operational stability. By understanding the dynamic characteristics of linear tapered roller bearings, engineers can design systems that operate smoothly and reliably, preventing potential failures and minimizing downtime.


EN ISO 8459-1:2012 serves as an invaluable tool for both bearing manufacturers and end-users. By providing standardized testing methods for determining the static and dynamic characteristics of linear tapered roller bearings, it contributes to the development of highly reliable and efficient systems in various industries. The adherence to this standard ensures that the specified performance parameters of these bearings are met, resulting in improved product quality and customer satisfaction.
