Product Features of NKIA 5908 Bearings

  • Aligning needle roller bearings are self-aligning and provide a compact solution in applications where space is at a premium.

  • They have a high load carrying capacity due to their large number of rollers. Their internal design, where the convex outer ring meets two concave seat rings encapsulated in a drawn sleeve, allows the bearing to accommodate initial static misalignment.

  • If the shaft can be hardened and ground, the inner ring-less bearing is the best choice for compact bearing arrangements.

  • High radial load carrying capacity

  • Adapts to static initial misalignment

  • low cross-sectional height

  • Suitable for compact bearing arrangements

Product classification of Needle roller bearings

FAQ

  • Ball bearings are ideal for high-speed rotation, while roller bearings are more suited for high loads.
  • Because cylindrical roller bearings have separable inner and outer rings, they generally do not come with seals (open specification). As such, please apply seals or other protection around the equipment mounting.
  • EW Series bearings are small and utilize a pressed cage, making them suitable for standard operating conditions. ET Series bearings use a polyamide-resin cage suited for high temperatures. Finally, EM Series bearings have machined cages for use in harsh conditions such as gearboxes or vibrating machinery or in applications where the bearing must be quiet, such as in mid-to-large size motors.
