Spherical needle roller bearings without inner ring

Spherical needle roller bearings offer compact solutions in applications where space is at a premium. Due to the large number of rollers, they have a high load carrying capacity. In their internal design, the use of a convex outer ring accommodates two concave seating rings in the tensile sleeve, enabling the bearings to withstand initial static misalignment. If the shaft cannot be hardened and ground, bearings without inner rings are the best choice for compact bearing arrangements.

  • High radial load carrying capacity
  • Can withstand static initial misalignment
  • Small cross-section
  • Suitable for compact bearing arrangements
