Product Description

Versatile multi purpose bearing designed for optimal performance & durability

Features & Benefits

  • Sealed configuration limits the entry of airborne contaminants during operation
  • Hardened steel races retain dimensional stability during extended rotation
  • Ball spacing promotes consistent load sharing throughout the bearing path
  • Smooth rolling action reduces audible vibration within enclosed housings
  • Compact bearing profile fits neatly into standardized mechanical assemblies

NTN Deep-Groove Ball Bearing

The NTN Deep-Groove Ball Bearing is built to manage rotational movement by allowing rolling elements to travel smoothly within a precisely formed raceway. This bearing type is commonly integrated into assemblies where shafts rotate continuously under steady radial loading. The straight bore allows the bearing to slide directly onto a shaft without modification while maintaining concentric alignment during operation. With an inner diameter of 17 mm and an outer diameter of 40 mm, the NTN 6203LU occupies a defined space that balances load handling with compact system layout.
