FAQ

What is the corresponding cup for the Timken NA495A cone?

The NA495A cone is designed to be paired with the Timken 493 cup to form a complete single tapered roller bearing assembly. Using any other cup is not recommended and can lead to premature failure.

What type of lubrication is suitable for this bearing?

The appropriate lubrication (oil or grease) depends heavily on the application’s speed, load, and operating temperature. For most general industrial applications, a high-quality NLGI No. 2 grease with an EP (Extreme Pressure) additive is suitable. Always consult your machine’s maintenance manual for specific lubricant requirements.

Is this bearing pre-set for a specific clearance or preload?

No, the NA495A cone itself is not pre-set. The final operating clearance (or preload) is determined during installation and is a function of the housing and shaft fits, as well as the axial adjustment relative to the mating cup (493). Proper setting is critical for optimal bearing life.
