FAQ

Question?
What cup is compatible with the Timken 745-S cone?

The 745-S cone is designed to be paired with the Timken 742 cup to form a complete single-row tapered roller bearing assembly.

Question?
What is the main advantage of using a case-carburized steel bearing?

Case-carburized steel provides a hard, wear-resistant surface while maintaining a softer, tougher core. This combination allows the bearing to handle heavy shock loads without fracturing, significantly increasing its durability and reliability in demanding applications.

Question?
Does this bearing require a specific type of lubrication?

Yes, like all tapered roller bearings, the 745-S requires proper lubrication to function correctly. The type of lubricant (oil or grease) depends on the operating speed, temperature, and load of the application. Always consult your equipment’s maintenance manual for the recommended lubricant specifications.
