Needle roller bearing NK21/20R＋IR17×21×20

Advantages:

• Low cross section
• High load carrying capacity
• High stiffness
• The possibility of assembling inner and outer rings separately permits interference fits for shaft and housing and also enables easy maintenance inspections
• Accommodate axial displacement
  Except for bearings with flanges on both the inner and outer rings, needle roller bearings with machined rings can accommodate axial displacement
• Accommodate static misalignment
• Locating bearing arrangement
  Combined needle roller bearings accommodate combined radial and axial loads in one or both directions
