Performance Characteristics:

  • Spherical Raceway: The outer ring raceway is spherical, allowing compensation for angular misalignment between shaft and housing.
  • Dual‑Row Configuration: The two ball rows distribute loads uniformly and maintain stable rotation under radial and moderate axial loads.
  • Tapered Bore 1:12: The K‑type tapered bore allows mounting on adapter sleeves and supports secure shaft seating.
  • Steel Cage: The pressed steel cage provides structural rigidity and consistent ball guidance.
  • CN Clearance: Normal internal clearance suitable for standard thermal expansion and alignment conditions.
  • Open Design: The absence of sealing elements allows external lubrication and direct inspection of the rolling elements.

The 1311.K RICH bearing is a self‑aligning ball bearing with a spherical outer raceway and a 1:12 tapered bore. The steel cage and CN clearance support stable operation in assemblies where shaft or housing misalignment may occur.
