Ball bearings from the inner, outer, inner and outer race is fixed between the steel ball and the ball of the support structure, its role is through the ball rolling, the average sliding friction to rolling friction, thereby reducing friction and improving with precision. Ball bearing can be said for the speed increase is contributed to the proper use of ball bearings can receive immediate results. The application of the four-wheel ball bearing has three main parts: 1) is widely used in vehicle axle Department, windows bearings specifications for the 6mm diameter ball bearings, so that rotation of the wheels more smooth; 2) after the cover for the motor bearings specifications 5mm in diameter, and the bearing must be enclosed to avoid being affected by impurities blocking performance of play; 3) 5mm diameter ball can also be used to guide wheel, available in the market-oriented multi-wheel,Inner bore hexangular with ball bearings, and ball bearing wheels can also be directly used as a guide.
