Structure types:

• Needle retainer assembly K/K...ZW/K...D/K...ZWD type series:
  • Needle roller cage assembly components related to the size of the fixed axial bearing assembly use
  • When using high -speed condition when the retainer and the axial limit should be added to a washer through the heat-treated in order to avoid to maintain direct contact with the limit

Features:

• Smaller cross-section leading to greated rigidity, higher load-carrying capacity and lower inertia of the needle roller bearings help size and weight reductions in machinery
• Though they are less wide, their load carrying capacity is high and is most suitable for applications where the load is high and the radial space is less
• Needle roller bearings, which are designed to withstand oscillation can operate under severe conditions and interchange with sliding bearings
