Product Features of C 2206 KTN9 Bearings

  • Adapting to misalignment
    CARB bearings are self-aligning in the same way as spherical roller bearings or self-aligning ball bearings.
  • Adaptation to axial displacement
    CARB bearings compensate for thermal expansion of the shaft, as cylindrical or needle roller bearings.
  • Available in various size series
    CARB bearings with the same boundary dimensions as the corresponding spherical roller bearings, self-aligning ball bearings, cylindrical roller bearings and needle roller bearings.
  • Long service life
    Special roller profiles prevent stress peaks at the roller ends.
  • Low friction
    Self-guided rollers keep friction and frictional heat at a low level.
  • Improved wear resistance
    All CARB bearings are upgraded to SKF Explorer bearings.
  • Low noise
    CARB bearings reduce noise and vibration levels, for example, in paper machines and fans.
  • Long bearing system life
    CARB bearings offer advantages in self-aligning bearing configurations. CARB bearings in the non-locating position do not generate internal axial forces, resulting in several benefits.
  • Reduced loads extend service life.
    The bearings run cooler, lubricants last longer, and maintenance intervals can be extended.
    Noise and vibration levels can be reduced.

Applications of C 2206 KTN9 Bearings

  • CARB circular roller bearings are unique: in addition to accommodating misalignments without increasing stress levels, they provide frictionless axial motion within the bearing in non-locating positions in self-aligning bearing configurations. They can withstand higher load levels and have a significantly longer service life.
  • The following are examples of applications where CARB circular roller bearings may be used.
  • Industrial drives
  • Metal
  • Pulp and paper
  • Mining, mineral processing and cement
  • Industrial fans
  • Marine

  • 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.
