Product features:
In order to obtain low friction torque, high rigidity and good rotation accuracy of bearings, steel balls with small outer diameter are used. The use of hollow shafts ensures lightweight and wiring space. The thin-walled bearing realizes the extremely thin bearing section, and also realizes the miniaturization and lightweight of the product. The variety of products expands its range of uses.
Thin-walled 6700, 6800, 6900 series have a variety of dust cover forms, with flange forms, stainless steel forms, wide forms, etc.
Application scenarios: Thin-wall bearings are widely used in high-precision, high-rotation speed, limited space and lightweight requirements, such as aerospace, robotics, medical equipment, semiconductor equipment and precision instruments. In addition, thin-wall bearings are also used in model aircraft, machine tools, motors and other equipment.
