Other salient points to be noted:
Engineered for severe industrial applications, the Timken Type TTDK 2 is a double-acting thrust tapered roller bearing that delivers exceptional axial load capacity. Like its counterparts, it is highly sought after for work roll axial positions in metals rolling mills. This specific variant integrates an outer-ring spacer with an oil groove, ensuring optimal lubrication and extended service life under extreme pressure.
-
Bearing Construction: Double-acting thrust tapered roller bearing.
-
Race Configuration: Features two single flat outer races and one double tapered inner race.
-
Advanced Lubrication: Includes one outer-ring spacer designed with a dedicated oil groove for consistent and efficient lubrication.
-
High Load Capacity: Built specifically to manage very high axial loads without compromising performance.
-
Ideal Application: Metals rolling mills and heavy-duty industrial machinery.
