Double-row Tapered Roller Bearings
Double-row Tapered Roller Bearings can replace two single-row tapered roller bearings mounted back-to-back or face-to-face when the required capacity exceeds that of single-row tapered roller bearings. If the tapered roller bearing contact lines converge away from the bearing axis, the bearing is more tolerant to misalignment. If they converge toward the axis, the tapered roller bearing has higher resistance to moment loading, but lower tolerance for misalignment.
Tapered roller bearings are widely used in roll-neck applications in rolling mills, transmissionsgear reducers, geared shafting, steering mechanisms, and machine-tool spindles. Where speeds are low, grease lubrication suffices, but high speeds demand oil lubrication -- and very high speeds demand special lubricating arrangements.
The parameters as follows:
