Other salient points to be noted: 

Built for maximum resilience, the Timken Type TTDFLK 2 is a high-performance double-acting thrust tapered roller bearing. It utilizes a flat inner race combined with tapered outer races to effectively distribute extreme axial loads. Widely used in the metals rolling industry for work roll axial positions, the TTDFLK 2 features specialized face keyways and oil slots to ensure both secure mounting and superior lubrication.

• Bearing Construction: Double-acting thrust tapered roller bearing.

• Race Configuration: Features two single tapered outer races and one flat inner race.

• Lubrication Management: Includes one outer-ring spacer complete with oil slots for optimal lubrication distribution.

• Mounting Options: Inner-ring face keyway is available as an optional feature to secure the bearing against high rotational forces.

• Ideal Application: Specifically tailored for metals rolling mills handling very high axial loads.
