NSK E / EN Series Magneto Ball Bearings

NSK E / EN Series Magneto Ball Bearings

NSK magneto ball bearings (E, EN, BO and L types), bore 4-20 mm; the outer ring has a single shoulder so the bearing can be separated for mounting.

Key features

  • Separable design: outer ring can be removed from the inner ring and ball set
  • Carries radial load and axial load in one direction
  • Compact, lightweight bearing for small generators, magnetos and instruments
  • E series outer ring tolerance is plus-toleranced as noted in the catalogue
