624-ZZ ECO Shielded Miniature Ball Bearing 4mm x 13mm x 5mm
Miniature ball bearings are one of the most commonly used bearing within many different industries. Metal shielded type miniature bearings are manufactured with metal shields which are inserted into the outer raceway and fit in closely to the inner race. The shields are designed to provide protection against the ingress of moisture, dust and other foreign matter and also serve to retain the pre-filled grease in the bearing. Shields can be removed for applications where only 1 shield is required.
