331775B Double Row Tapered Roller Bearings

TDO design bearings have a double row outer ring and two single inner rings that usually have an intermediate ring between them. Their roller sets are arranged back-to-back (O-arrangement), which enables them to accommodate tilting moments. Design variants include features such as a helical groove in the bore or lubrication grooves in the side faces of the bearing rings.

Features:

High radial load carrying capacity

Accommodate axial loads in both directions

Relatively high stiffness

Accommodate tilting moments

Many variants, including a helical groove in the bore or lubrication grooves in the side faces of the bearing rings
