Product Overview
  • NN3020 is a double-row super precision cylindrical roller bearing with straight inner bore, dimension 100×150×37mm. It adopts NN structural design with double ribs on inner ring and rib-free separable outer ring, which enables easy assembly and disassembly. This bearing bears heavy pure radial loads and delivers ultra-high rigidity, supporting high-precision stable rotation at medium-high speed. Optional W33 lubriion groove, brass cage and P4/P5 high precision grades are available. It is the core spindle bearing widely applied to CNC lathes, grinding machines and other precision machining equipment.
