6400 Series Deep Groove Ball Bearings


  • massive series with compact dimensions and high weight
  • can carry much higher radial loads despite the same inside diameter than deep groove ball bearings of series 60, 62 and 63
  • suitable for high radial loads and light axial loads in both directions
  • offers high running accuracy, quiet running and high speeds
  • seal: contact lip seal on both sides made of rubber (2RS) for high sealing effect
  • 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. Ball bearings of the 64 solid series can support considerably higher load-ratings at the same inside diameter than deep groove ball bearings of the 60, 62, and 63 series. They have a double load carrying capacity compared to deep groove ball bearings of the 62 light series, for example.

The bearings we provide can meet almost any operating accuracy requirements and application speed: our bearings have Abec tolerances of 1-9, internal clearances from C2 to C4, and several different cage designs, including J type, W Type, RJ type, TW type and so on.

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.

Massive variant for high radial loads. The deep groove ball bearing 6403-2RS is a true all-rounder and, due to its balanced properties, it is suitable for a variety of applications, in particular for high radial loads. Main dimensions according to DIN 625-1.

Other options: Metal shield (ZZ) or rubber seal (2RS) can be provided.

6000 series
6400 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
