88602 Nonstandard Deep Groove Ball Bearings Advantages: 1. High operation precision; 2. Most rolling bearings can also be subjected to radial and axial loads, so the combined structure of bearings is simple; 3. For axle diameters of the same size, the width of rolling bearing is smaller than that of sliding bearing, which can make the axial structure of machinery compact; 4. Under ordinary conditions, the efficiency of rolling bearing is equal to that of hydrodynamic smooth bearing, but higher than that of inclusion smooth bearing.
