Product Features of RNAO 30X40X17 Bearings

  • low cross section
    In applications where space is at a premium, drawn cup needle roller bearings allow for miniaturization.
  • high load capacity and stiffness
    Due to the large number of rollers, drawn cup needle roller bearings have high load carrying capacity and rigidity.
  • good running performance

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.
