Bearing Load Ratings: Understanding Capacity Specifications
Load ratings indicate bearing capacity and guide selection. Understanding these specifications ensures appropriate bearing choice for applications.
Basic Dynamic Load Rating
This specification defines load capacity under laboratory conditions. It represents the load a bearing can endure for one million rotations before fatigue failure.
Static Load Rating
Static load rating indicates capacity for stationary loads. This matters for applications with minimal rotation or impact loads.
Equivalent Dynamic Load
Combined radial and axial loads convert to an equivalent value for comparison with rated capacity. Proper calculation ensures adequate bearing selection.
Application Adjustments
Contamination, lubrication, temperature, and speed affect actual capacity. Apply appropriate factors to laboratory ratings for reliable application.
