NACHI Excel 68 Series Deep Groove Ball Bearings (2NSE, 2NKE, ZZE)

NACHI Excel 68 Series Deep Groove Ball Bearings (2NSE, 2NKE, ZZE)

NACHI Excel series 68 type thin-section radial ball bearings, bore 10 to 50 mm, with contact seals (2NSE), labyrinth seals (2NKE) or shields (ZZE).

Key features

  • Excel series design with special triple-lip seals: contact type (2NSE) and labyrinth/non-contact type (2NKE), plus shielded type (ZZE)
  • Low starting and running torque from a revised internal design with diminished axial play
  • Improved accuracy of rolling elements for reduced running noise and enhanced sound quality
  • Pre-lubricated with long-life grease; high-performance seals keep out dust
  • Replaces the previous 2NSL, 2NK and ZZ closures (e.g. 6203-2NSE replaces 6203-2NSL)
