What are the implications of the static and dynamic load ratings?
The static and dynamic load ratings indicate the maximum loads that can be safely applied without causing permanent deformation or failure. With a radial static load rating of 16.3 kN, this product can effectively handle heavy loads, while the dynamic rating of 11.4 kN allows for optimal performance during operation.
How does the high-speed capability affect its operation?
The high-speed capability enhances efficiency and performance in dynamic applications. With a reference speed of 18,000 r/min and a limiting speed of 20,000 r/min, it minimises friction and heat generation, resulting in increased longevity and reliability in demanding operational conditions.
What is the significance of the fatigue limit loads provided?
The fatigue limit loads indicate the maximum load a bearing can endure over extended use without experiencing fatigue failure. With radial and axial fatigue limits of 1.96 kN and 0.116 kN respectively, this product is engineered for applications with repeated load cycles, ensuring consistent performance over time.
