Ball bearings to adapt to a variety of purposes, providing a wide range of standardized products. Widely used in machine tools, ball circulation patterns have circulation conduit type, circulator type, cover type. Preload preload positioning (double nut way, bit preload), constant pressure preload. You can select the appropriate type according to the application. Screw with high-precision grinding of precision ball screws (accuracy divided from CO-C7 of six levels) and by high precision cold rolled ball screw bearings molding (precision into the C7-C10 3 levels). Ball bearing common way of ball screw according to the situation by force at work, often screw supporting the thrust bearing and radial ball bearing assembly, which is supported in the following ways: 1, single push of a single push stop thrust bearing and preload were installed at both ends of the ball screw. It can improve the axial stiffness of the ball screw; Ball when buying pre-stretched installation, buy larger preload ball screw, lead screw and therefore bear only work when pulling. 2, one pair of push-push-push attached to both ends of the thrust bearing and radial ball bearings combined supply of ball screw, as the screw has a maximum rigidity of the ball screw, it can be used at both ends of double bearing, thrust bearing, and lasts radial ball bearings, and clamping force is applied to the top. This method is suitable for high rigidity, high-speed high-precision precision lead screw drive system. However, this structure allows the thermal deformation mode conversion screw preload the thrust bearing, thus requiring stents increase the carrying capacity and stiffness of the thrust bearing design.
