SKF needle roller bearings SKF NKXR 20 Z

This type of bearing consists of radial needle roller bearings and cylindrical roller thrust bearings. Modular bearings are capable of withstanding radial and unidirectional axial loads. Its small cross-section makes it particularly suitable for equipment applications where other types of locating end bearing arrangements take up too much space. Thrust ball bearings are guarded to create an intermittent seal that retains grease within the bearing.

  • It can withstand radial and unidirectional axial loads
  • High load-bearing capacity
  • Small cross-section
