F-6700 Series Deep Groove Ball Bearings (Flanged)


  • thin section bearing with an ultra-thin, square cross-section
  • suitable for space-saving installation in radial and axial directions
  • suitable for extremely high speeds compared to deep groove ball bearings with a larger cross-section
  • extra light series with compact dimensions and low weight
  • suitable for radial loads and light axial loads in both directions
  • offers high running accuracy, quiet running, and very high speeds
  • seal: contact lip seal on both sides made of rubber (2RS) for high sealing effect
  • the good fixed bearing property, but can also be used as a floating bearing, each in both directions

Special feature of this series

Main dimensions according to DIN 625-1. Thin section bearings of the F-67 series are equipped with a flange for simplified locating bores in which the bearing is supposed to be axially fixed. They still have smaller dimensions than thin section bearings of the 68 series with their ultrathin, square cross-section at the same inside diameter. In comparison to their inside diameter they have an extremely small outside diameter – and furthermore – they are extremely narrow. Relatively high shaft- and axis diameters can thereby be installed at an also extremely confined installation space. They are extremely light and are suitable for comparatively very high speeds.

Rubber seals (RS/2RS) have the optimum sealing action with increased friction. Metal seals (Z/ZZ) are suitable for higher speeds, but they have a limited sealing action as they seal contactless. Open, seal-less bearings are suitable for extremely high speeds and – furthermore – they can be regreased more easily. However, they are more susceptible to soiling.

Manufacturers of bearings: such as FAG, KOYO, NSK, SKF, SNR, etc. assign different suffixes for their characteristics, for better orientation take note of the comparison table of bearings (see further information)

Can be customized to meet your specific needs.

6000 series
F-6700 Series -TFL

Deep Groove Ball Bearings are able to accommodate low to heavy radial loads and low to moderate thrust loads in either direction. They are available with metal shields (ZZ) or rubber seals (2RS). Several tolerance grades (Abec 1-9), internal clearance (C2 to C4) and cage designs are available to best suit the running precision and speed of the application.

Common Options:

  • ZZ– Two Metal Shields
  • 2RS– Two Rubber Seals
  • NR– Snap Ring
  • M– Brass Cage
  • C0– Normal Internal Clearance
  • C3– Greater than normal
