Alignment Needle Roller Bearings

Our alignment needle roller bearings have an outer ring with a sphered (convex) outside surface. Two polymer seating rings with a sphered (concave) inside surface are encased in a drawn sheet steel sleeve and fitted over the outer ring. You can get alignment needle roller bearings with an inner ring or without an inner ring.

The structure of alignment needle roller bearings allows any eventual shaft deflection to be absorbed, up to a maximum of 2°/3°. The main feature of alignment needle roller bearings is the self-aligning outer ring, thanks to a series of plastic support rings inserted between it and the drawn cup.

Types of Alignment needle roller bearings

We supplies alignment needle roller bearings with or without an inner ring. We provide RPNA and PNA Series alignment needle roller bearings.

Bearings with an inner ring

  • should be used in applications where the shaft cannot be hardened and ground.
  • have limited permissible axial displacement of the shaft relative to the housing, which can be extended, if needed, by using a wide inner ring (Needle roller bearing components – Inner rings).

Bearings without an inner ring

  • are an excellent choice for compact bearing arrangements, if the shaft can be hardened and ground.

Features of Alignment needle roller bearings

  • Accommodate static misalignment
    Alignment needle roller bearings are self-aligning up to 3° of static misalignment.
  • Low cross section
    In applications where less space is available, alignment needle roller bearings offer a compact solution.
  • High carrying capacity
    Owing to their large number of rollers, alignment needle roller bearings have a high load carrying capacity.

Appilications of Alignment needle roller bearings
