Tapered Roller Bearings Brief introduction
Taper roller bearings are applicable to bear load with in radial direction load primarily and axial load combination,
and the big cone Angle taper roller bearings can be used to bear combined load that axial load primarily with radial
and axial direction.These bearings are separating type bearings, their inner rings (including tapered rollers and cage)
and outer rings can be installed separately. In the installation and using process you can adjust to the bearing radial
clearance and axial clearance, preloaded mounting can be made.
Tapered roller bearings structure
Inner ring ,outer ring,rollers,cage
Cage material :steel (only)
Tapered roller bearings' inner ring and outer ring can be separated .
There is only one model number for tapered roller bearing in international standard .
and it is two models in inch nonstandard ,export bearing has single package for two rings.
