SF688-2RS Budget Flanged Stainless Steel Sealed Miniature Ball Bearing 8mm x 16mm x 5mm
Miniature ball bearings are one of the most commonly used bearings 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.
Flanged miniature ball bearings have a solid steel flange on the outer ring. This allows the bearing to be easily located in a housing. The flange helps to prevent axial movement of the bearing in the event of it being subject to thrust load. It is easier to maintain the position of a flanged bearing in the housing where a lot of vibration is present.
