Timken Part Number M241547C - M241513D, Tapered Roller Bearings - TDO (Tapered Double Outer) Imperial



Tapered Roller Bearings - TDO (Tapered Double Outer)

larger image
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.
