What are the implications of the race width for performance in specific machines?


The race width influences load-bearing capacity and overall stability. A width of 20mm ensures adequate support for various operating conditions, reducing stress on surrounding components.

How does the static load rating affect selection for industrial applications?


A static load rating of 32.5kN provides a safety margin in bearing applications, ensuring it can handle sudden shocks or overloads without permanent deformation.

What temperature limits should be considered for optimal performance?


While specific temperature limits are not stated, standard operating conditions for steel bearings generally allow for efficient functioning within typical industrial temperature ranges. Always consult technical specifications for precise limits.
