Deep Groove Ball Bearings FAG 6003 -Z-C3

The FAG 6003 -Z-C3 deep-groove ball bearing, with a 17 mm bore, a single-sided cover plate and increased bearing clearance, ensures reliable operation under thermal loads.

The 6003 -Z-C3 deep groove ball bearing is a single-row radial ball bearing with an internal diameter of 17 mm, an external diameter of 35 mm and a width of 10 mm. As a versatile rolling bearing, this design primarily accommodates radial forces as well as moderate axial forces in both directions. Manufactured from 100Cr6 bearing steel and fitted with a sheet steel cage, this design is used where compact installation spaces and reliable guidance of rotating shafts are required.

What installation conditions make the 6003 -Z-C3 deep groove ball bearing suitable?

This bearing design is primarily used in bearing locations with a targeted lubricant supply or a protected installation space. The single-sided sheet metal cover leaves one side of the interior open, allowing liquid lubricant such as lubricating oil to circulate unhindered or to be re-lubricated from the open side. At the same time, the metal cover shield the raceway from coarse dirt particles on the outer side. This design is therefore suitable for housing constructions where one side needs to be protected against contamination and the other side must remain open for lubricant supply.

When is the combination of a Z cover ring and C3 bearing clearance appropriate?

The C3 designation indicates a slightly increased radial bearing clearance compared with the standard version. This helps to prevent the rolling elements from becoming stressed when temperature differences occur between the inner and outer rings during operation, or when tight fits reduce the operating clearance. The single-sided gap seal operates without contact, causes no additional frictional torque and is therefore suitable for higher speeds. With tolerance class P0 or ABEC 1, the bearing meets the standard requirements in general mechanical engineering.
