Features of Round Flanged Linear Ball Bearings

The LMF type linear ball bearing is used in conjunction with the cylindrical LM optical axis, which is a linear motion system that can complete infinite linear motion. The load bearing steel ball and the LM optical axis are in point contact, and the allowable load is small, but it can achieve high-precision and brisk linear motion with minimal frictional resistance.

The bearing sleeve is made of high carbon chromium bearing steel, and its inner and outer surfaces are ground after heat treatment.

Linear ball bearings have a wide range of applications, including office equipment and its peripheral equipment, various measuring instruments, automatic recording devices and digital three-dimensional measuring instruments and other precision instruments; as well as multi-axis drilling machines, punching machines and tool grinders, automatic gas cutting equipment, Sliding parts of industrial machinery such as printing machinery, card sorting machines, and food packaging machines.

Flanged linear bearings are widely used in electronic equipment, tensile testing machines and digital three-dimensional coordinate measuring equipment and other precision equipment, as well as multi-axis machine tools, punching machines, tool grinders, automatic gas cutting machines, printers, card sorting machines, food packaging machines and other industries Mechanical sliding parts.

The biggest feature of the flanged linear ball bearing is that the flange and the bearing are integrated. A series of products with flanges on the outer wheel makes axial positioning simple; no bearing housing is required, making it more economical. When there is no connecting piece at one end of the shaft and it needs to be fixed on a flat surface such as a plate or a wall, the flange bearing shows its advantages. In order to obtain low friction torque, high rigidity, and good rotation accuracy of the bearing, steel balls with small outer diameters are used. The use of hollow shafts ensures light weight and space for wiring.
