Description
Product Description
Flanged bearings have a solid steel flange on the outer ring. This allows the bearing to be more easily located in a housing. The flange can also help to prevent axial movement of the bearing in the event of a thrust load on the bearing. It is easier to maintain the position of a flanged bearing in the housing where a lot of vibration is present.
Product Features:
---A series of products with flanges on the outer wheel makes axial positioning simple; no bearing housing is required, making it more economical;
---In order to obtain low friction torque, high rigidity, and good rotation accuracy of the bearing, steel balls with a small outer diameter are used;
---The use of hollow shafts ensures light weight and space for wiring.
