What are the static and dynamic load ratings for this bearing?

The static load rating is 69.5 kN, while the dynamic load rating is 25 kN. These ratings indicate the maximum loads the bearing can support without suffering damage during operation.

How does the non-metallic cage contribute to bearing performance?

The non-metallic cage reduces friction and wear, resulting in lower heat generation during operation, which enhances the overall lifespan of the bearing.

What are the implications of operating at limiting speeds of 6300 r/min?

Operating at limiting speeds of 6300 r/min allows for high-performance applications. It ensures the bearing can effectively manage reduced wear while achieving optimal operational efficiency at elevated speeds.

In what settings is this type of bearing preferred over thrust ball bearings?

Cylindrical roller thrust bearings are preferred in applications where high axial loads and speeds are present. Their design allows for better load distribution compared to thrust ball bearings, making them suitable for rigorous mechanical environments.
