689-2RS JWE Sealed Miniature Ball Bearing 9mm x 17mm x 5mm
Miniature ball bearings are one of the most commonly used bearing within many different industries. Rubber sealed type miniature bearings are manufactured with rubber seals inserted into the outer raceway and in contact with the inner race. The seals 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. Seals can be easily removed for applications which require only 1 seal.
