Double row tapered roller bearings provide a stiff bearing arrangement. Low friction The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. In addition, the bearings can better maintain preload and run at reduced noise levels.
TDO (Two-Row Double-Outer Race) The configuration of the TDO provides a wide effective bearing spread, making it ideal for applications in which overturning moments are a significant load component. TDO bearings can be used in fixed positions or allowed to float in the housing bore. Size range:
Single row taper roller bearings and matched paired sets RKB taper roller bearings have the rolling elements under the form of frustum of cone. They roll on tapered surface which, if extended, converges towards a single point on the bearing axis.
Tapered roller bearing cones and assemblies with a double row design can have three basic arrangements. The face-to-face (TDI) configuration joins the load lines toward the axis, the back-to-back (TDO) configuration separates the load lines toward the axis, and the tandem configuration sets the load lines parallel to one another.
