Deep groove ball bearing bore tolerance selection and control: deep groove ball bearing pressure into deep groove ball bearing, flexible rotation without obstruction. If you don't flexible rotation obviously, means the size of the shaft is too large, the tolerance should be downward adjustment. If the deep groove ball bearing pressure into the shaft rotation, with the hand will have obvious 'sasha vujacic' feeling, this may be the shaft or shaft roundness tolerance is too big. As a result, the control shaft and deep groove ball bearing chamber of tolerance, should also be well control the roundness. At present, many domestic manufacturers control tolerance and not only control the roundness. 2. Deep groove ball bearing assembly methods: because deep groove ball bearings are high precision products, therefore, if improper deep groove ball bearing assembly, it is easy to damage the deep groove ball bearings. Deep groove ball bearings. Deep groove ball bearing in the assembly should have special mold. Can't knock it. Only by small ring at the pressure into the shaft stress, and is large ring press can only ring under high stress. The need when assembling pneumatic or hydraulic, when the force fit on mould and lower mould should be in the level state. If the tilt, the deep groove ball bearings of the groove will be damaged due to the force, and will cause deep groove ball bearings. 3. Prevent foreign body assembly: deep groove ball bearing installation progresses in rotor dynamic balance, it is easy to will be produced in the process of dynamic balance iron into the deep groove ball bearings. , so it's best to install deep groove ball bearing is a dynamic balance. For ease of assembly, some manufacturers in deep groove ball bearing chamber with some oil or grease for lubrication, but the operator is usually difficult to control its use. If oil, deep groove ball bearing chamber accumulated deep groove ball bearing rotates, it is easy to along axis to the deep groove ball bearings. Deep groove ball bearing chamber is best not to apply oil or grease. If there is no need to, you must control it do not accumulate in the deep groove ball bearing chamber.
