Robust performance by Skf

  • High radial load support: You accommodate heavy radial forces reliably thanks to the optimized roller set geometry.
  • Quick and separable mounting: You install inner and outer rings independently, making assembly and maintenance straightforward in tight spaces.
  • Smooth low friction running: The sturdy pressed sheet cage guides rollers accurately to reduce friction and minimize heat buildup.

With the Skf nu 309 ecj cylindrical roller bearing, you handle heavy radial loads reliably in electric motors, gearboxes, and industrial machinery. Featuring an nu design with no flanges on the inner ring, it smoothly accommodates axial displacement caused by thermal shaft expansion. Its separable construction allows you to mount and dismount inner and outer rings independently, making installation and routine maintenance straightforward. The sturdy cage guides the rollers precisely to minimize friction and heat buildup during continuous operation. Sized at 45 x 100 x 25 mm with standard normal radial clearance, this open single-row bearing delivers dependable support for demanding rotating equipment.

Product description

Single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. Having two integral flanges on the outer ring and no flanges on the inner ring, NU design bearings can accommodate axial displacement in both directions. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.

  • High radial load carrying capacity
  • Low friction
  • Long service life
  • Accommodate axial displacement in both directions
  • Separable design
