FAQ

What does the 'C3' suffix in 6004ZZC3 mean for my application?

C3 indicates a radial internal clearance greater than standard (CN). This is beneficial in applications where the bearing is subject to a press fit on the shaft or in the housing, or where there are significant temperature differences between the inner and outer rings, as it prevents the bearing from seizing under load.

The 'ZZ' suffix denotes non-contact metal shields on both sides. They are excellent for retaining grease and protecting against larger solid contaminants. However, for environments with fine dust, high moisture, or direct water spray, a bearing with contact rubber seals (suffix 2RS) would provide superior protection.

This bearing comes pre-lubricated from the factory with a specific grease (indicated by the NS7S5 code). While it's technically possible to wash out the old grease and re-lubricate, it's not recommended as it can introduce contaminants and may not be compatible with the original cage material. For optimal performance and lifespan, it's best to use the bearing as supplied.
