Double Row TNA Series

Double row tapered roller bearing TNA bearings are non-adjustable, double-row bearings that are supplied with built-in clearance.This results in a specifified mounting setting range satisfactory for specifific applications. They are similar to type TDO, but the  inner-ring front faces are extended so that they abut, which eliminates the need for the  inner-ring spacer of a TDO bearing.They can be used at either fixed positions or allowed to float in the housing bore to compensate for shaft expansion.


For desired fifitting practice and resultant mounted setting  range information, contact your VAFEM engineer. If a closer control of mounted setting range is required, type TDO bearing assembly is recommended.
