Double-Row Tapered Roller Bearings (TDO Type)
This type of bearing is composed of a double cup, two cone assemblies and a cone spacer. The bearing internal clearance has already been set using the cone spacer, so parts must be combined according to the serial number and matching symbol. The double cup has an oil slot and some oil holes.This type of bearing can carry both radial and axial loads, so it can be used as a fixed-end bearing. It is also used frequently on the free end to relieve the shaft elongation or contraction between the cup and housing.
