Product Features of 319434 B-2LS Bearings

  • high carrying capacity
  • high stiffness
  • Adapt to axial displacement
    Bearings with ribs on both inner and outer rings are excluded.
  • low friction
  • Open flange design
    Together with the roller end design and surface finish, it promotes lubricant film formation, which reduces friction and increases axial load capacity.
  • long lasting
    Logarithmic roller profile reduces edge stress at roller/raceway contact and susceptibility to misalignment and shaft deflection.
  • Enhanced operational reliability
    The surface finish of the roller and raceway contact surfaces supports the formation of a hydrodynamic lubricant film.
  • separable and interchangeable
    The separable parts of cylindrical roller bearings are interchangeable. This facilitates installation and removal as well as maintenance inspections.

FAQ of 319434 B-2LS Bearings

  • 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.
