Other salient points to be noted: 

The Timken Type TTDFLK 1 is a robust, double-acting thrust tapered roller bearing featuring an alternative "flat inner, tapered outer" race design. It is engineered to excel in metals rolling mill applications, specifically on work roll axial positions where managing massive axial loads is critical. This configuration includes a spacer with oil slots to maintain excellent lubrication during intense operations.

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

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

• Lubrication Management: Equipped with one outer-ring spacer featuring machined oil slots for optimal fluid flow.

• Mounting Options: Inner-ring bore keyway is available as an optional feature for anti-rotation security.

• Ideal Application: Designed extensively for work roll axial positions subject to very high axial forces.
