F684 Budget Flanged Open Miniature Ball Bearing 4mm x 9mm x 2.5mm
Miniature ball bearings are one of the most commonly used bearings within many different industries. Open type miniature bearings are manufactured without seals and shields to allow oil and grease to flow freely through the bearing for lubrication purposes, They are versatile, robust and fairly easy to maintain.
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.
