Other salient points to be noted: 

The TTHDFL nomenclature designates Timken’s premium line of Tapered Thrust Heavy-Duty Free Lateral Bearing, engineered for extreme environments, this Timken bearing combines the outstanding features of both thrust tapered and cylindrical roller bearings. The result is the highest possible load capacity of any thrust bearing of its size on the market today. 

• Unique V-Flat Configuration: Consists of one thrust tapered race, one flat race, rollers, and a cage to ensure true rolling motion and maximize operational efficiency.

• Maximized Load Capacity: Larger sizes utilize specialized pin-type cages with hardened pins running directly through the center of the rollers. This allows for tighter roller spacing, dramatically increasing the bearing's overall load capacity.

• Precision Cage Design: Smaller sizes feature precision-machined brass cages designed specifically for the secure, unidirectional retention of rollers.

• Heavy-Duty Reliability: Originally developed for high-stress screwdown applications in metal rolling mills, making it the ideal solution for any industrial application where exceptionally high axial loads are common.
