Flange Bearings

Classification:

Flange Bearings

Flange bearings are a series of products with flanges on the outer wheels, making axial positioning easy; bearing housings are no longer needed, making them more economical. In order to obtain low friction torque, high rigidity and good rotary accuracy of the bearings, steel balls with small outer diameter are used. The use of hollow shafts ensures light weight and space for wiring. Flange bearings are a combination of flanges and bearings, which show their advantages when there is no connection at one end of the shaft and it needs to be fixed on a flat surface such as a plate or wall.
