KBC K Series Needle Roller and Cage Assemblies (K, K...ZW)

KBC K Series Needle Roller and Cage Assemblies (K, K...ZW)

KBC K series needle roller and cage assemblies in single-row (K) and double-row (K...ZW) designs. They run directly on a hardened shaft and housing bore, giving high load capacity in a very small radial section.

Key features

  • High load capacity with low section height
  • Single-row K and double-row K...ZW designs
  • PC: polyamide cage; SP: split-cage execution
  • Shaft and housing raceways must be hardened and ground

Specifications

Type Needle roller and cage assembly
Cage Glass-fibre reinforced polyamide (PC)
