Needle roller and cage assemblies

  1. Needle roller bearing–needle roller cage assembly  is a roller bearing with cylindrical roller, relative to its diameter, the roller is both thin and long.
  2. This roller is called needle roller
    Needle roller bearings are equipped with thin and long rollers (roller diameter D ≤ 5 mm, L/D ≥ 2.5, L for roller length), so the radial structure is compact, especially suitable for radial installation size is limited support structure.
  3. SKF needle roller and cage assemblies are self-contained, ready-to-mount bearings.
  4. In applications where the shaft and housing bore can serve as a raceway, this component can be used to create bearing arrangements requiring minimal radial space.

Features and Benefits

  1. high stiffness needle roller cage assembly

  2. High-quality materials provide high rigidity and can withstand heavy loads and shock loads. These bearings are available with or without an inner ring. Types without an inner ring use the shaft directly as the raceway surface.

  3. Internationally interchangeable
    Internationally standardized size series based on ISO and MIL standards are available.

  4. Skf needle roller cage assembly Ideal for machine tools
    These bearings offer high rigidity and high precision, making them ideal for machine tools and other applications requiring high-speed rotational accuracy under heavy loads.

  5. Smallest cross section in a rolling bearing–Needle roller cage assembly
    Needle roller and cage assemblies provide a very compact solution in applications where the available space is small.
  6. High load-bearing capacity–Needle roller cage assembly
    Due to the high number of rollers, needle roller and cage assemblies have a high load carrying capacity.
  7. High stiffness–Needle roller cage assembly
    Due to their large number of small diameter rollers, needle roller and cage assemblies have a high stiffness.


  1. Skf needle roller bearing are bearing units that are a combination of radial needle roller bearings and thrust bearing components.
  2. They are used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery and printing machinery, and can be designed to make mechanical systems very compact and nimble.

Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.

Successful mounting is critical to the life cycle of your bearing. Proper bearing dismounting can safeguard other machine components and maintenance workers.

  1. The bearing is at the heart of all rotating equipment, and the condition of the bearing often reflects how well a machine is running.
  2. Learn more about bearing damage and bearing failure – and how to prevent it.
