The 604ZZ is a miniature budget deep groove chrome steel ball bearing fitted with metal shields inserted into the outer raceway.
The metal shields on these bearings offer protection against light mechanical damage and also against the ingress of moisture and dust.
The shield also retains the pre-filled grease in the bearing reducing maintenance.
The small 4 x 12 x 4mm size of these miniature bearings makes then very useable within the modelling hobby.
This bearing will fit on all of our 4mm diameter motor and steel shafts.
