This bearing is a single-row deep-groove ball bearing with integral rubber seals on both sides, designated as a 6004 2RS type. It is intended for use in workshop equipment and similar mechanical assemblies where it supports a rotating shaft within a housing. The bearing's seals prevent the ingress of dirt and retain the internal grease, reducing the need for re-lubrication during service. A worn bearing will produce audible noise, vibration, or increased rotational resistance. On installation, ensure the shaft and housing bore are clean and that the bearing is pressed onto the shaft using the inner ring face only.
