NSK BL Series Maximum Type Ball Bearings (BL2, BL3)

NSK BL Series Maximum Type Ball Bearings (BL2, BL3)

NSK BL2 and BL3 series maximum type ball bearings, bore 25-100 mm, with a filling slot that allows a larger number of balls than a standard deep groove ball bearing.

Key features

  • Filling-slot design holds more balls for higher radial load capacity
  • Same boundary dimensions as 62 / 63 series deep groove ball bearings
  • Not suited to heavy axial loads because of the filling slot
  • Available open; Z and ZZ shielded versions are shown in the catalogue

Specifications
