No cage needle roller bearings with inner ring
NA , NKI type bearings without inner ring shall be RNA , NK type needle roller bearings . Such bearings without inner ring , suitable for installation dimensions restricted radial supporting structure , and bearing directly as a journal to match rolling surface . As a raceway axis , we must quench the hardware and make grinding , and only be processed to the appropriate size and shape accuracy , the full set of needle roller bearings can be a higher life expectancy and operation of precision . At the same time , because no inner ring , the diameter of shaft can also be appropriate to increase , thereby also increased rigidity .
