FAQ

What cone assembly is compatible with the Timken 493D double cup?

The 493D cup is designed to be used with two single cone assemblies. The standard mating cone is the Timken 494A. Always verify your application's specific requirements before assembly.

The 'HP' designation stands for High Performance. It indicates that the bearing is manufactured with enhanced geometry, surface finishes, and material cleanliness, resulting in higher load ratings, reduced friction, and longer service life compared to standard bearings.

No, this product is only the 493D double cup (outer ring). The cone assemblies (inner rings with rollers) must be purchased separately to form a complete tapered roller bearing.
