WON ST Crossed Roller Bearing CH Series, High-Rigidity Integral Type with Mounting Holes

WON ST Crossed Roller Bearing CH Series, High-Rigidity Integral Type with Mounting Holes

High-rigidity crossed roller bearing with integral inner and outer rings and mounting holes in both rings, giving small installation error for applications where the inner and outer rings rotate together or individually.

Key features

  • Integral inner and outer rings for minimal installation error
  • Mounting holes in both rings, no housing or retainer plate needed
  • Bears radial, axial and moment loads simultaneously
  • Spacer retainer prevents roller collision, friction and skewing
