Other salient points to be noted:
The Timken Type TTDK 1 is a premium double-acting thrust tapered roller bearing built to withstand the rigorous demands of metals rolling mills. Specifically designed to support work roll axial positions under very high axial loads, this bearing ensures operational stability. The TTDK 1 variant utilizes a tapered inner race design with a keyed bore for secure shaft mounting.
-
Bearing Construction: Double-acting thrust tapered roller bearing.
-
Race Configuration: Features two single flat outer races and one double tapered inner race.
-
Secure Mounting: Includes an inner-ring bore keyway to prevent rotation on the shaft and ensure secure engagement.
-
Heavy-Duty Performance: Optimized for exceptionally high axial loads.
-
Ideal Application: Extensively used in work roll axial positions in rolling mill applications.
