Deep Groove Ball Bearings FAG 6003 -RSR

The FAG 6003-RSR deep-groove ball bearing, measuring 17x35x10 mm, offers compact dimensions and one-sided protection against the ingress of dirt under radial loads.

The FAG 6003-RSR deep groove ball bearing is a single-row radial ball bearing made from standard rolling-element bearing steel (100Cr6). Fitted with a sheet steel cage and manufactured to tolerance class P0/PN (corresponding to ABEC 1), the design is suitable for a wide range of industrial applications. The rolling elements run in deep grooves without a flange or groove on the outer ring. With standard radial bearing clearance, the bearing is designed for typical operating conditions and covers a permissible temperature range from –30 to +100 degrees Celsius.

In which installation situations is the 6003-RSR deep groove ball bearing used?

This rolling bearing is primarily designed to accommodate radial forces as well as moderate axial forces in both directions. Designs with single-sided sealing are typically used where one side of the bearing needs to be protected from external contamination, whilst the opposite, open side maintains direct contact with the internal lubrication circuit of a housing or gearbox. This arrangement eliminates the need for separate sealing elements on the outside of the housing and facilitates compact shaft mountings in mechanical engineering.

What is the function of the single-sided RSR seal?

The suffix RSR denotes a single-sided, sliding contact seal. The elastic sealing lip rests directly against the inner ring and helps to keep fine particles or moisture out of the bearing’s interior. On the open opposite side, the gap between the inner and outer rings remains freely accessible. During assembly, care must therefore be taken to ensure the correct installation direction, so that the sealing disc faces the side of the potential source of contamination.
