331640A 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
Ready to mount
