Deep groove ball bearing should be paid attention to when using the matters

Jiaxing bearing group sales co. , LTD. Is established in retail sales company, has years of experience in HRB bearing sales, purchasing HRB brand - in order to better service Users of deep groove ball bearings, deep groove ball bearing and more users, jiaxing bearing today when used as an introduction to deep groove ball bearing matters should be paid attention to. 1, shaft, and the choice of deep groove ball bearing chamber of tolerance and control: deep groove ball bearing pressure into the deep groove ball bearing should be flexible rotation without block. If there are any obvious rotation is not flexible, indicates the size of the shaft is too big, tolerance to downgrade. Such as deep groove ball bearing pressure into the shaft by hand after the rotation has obvious sasha vujacic feeling, may be the shaft or shaft roundness tolerance is too big. So in good control of axis and deep groove ball bearing chamber of tolerance when also want to control the roundness, at present many domestic manufacturers to control the tolerance only, not to control the roundness. 2, deep groove ball bearing assembly way: because of deep groove ball bearings are high precision products, such as improper assembly is easy to cause damage to deep groove ball bearing channel, lead to damage of deep groove ball bearings. Deep groove ball bearing in the assembly shall have a dedicated mold, not casually, only small circle of stress when pressure into the shaft, pressure can force the circle circle. Require the use of pneumatic or hydraulic assembly, lower die when being connected to outside the state level, if there are any tilt will lead to deep groove ball bearing channel due to mechanical damage, and makes deep groove ball bearing guide ring. 3, the assembly to prevent foreign body: deep groove ball bearings in loaded on the rotor dynamic balance when it is easy to dynamic balance of iron into internal deep groove ball bearing, so it is best to put before the deep groove ball bearings do dynamic balance. There are some manufacturers in order to convenient assembly, assembly time in deep groove ball bearing indoor apply some oil or grease lubrication effect, but usually operators good amount of it is hard to control, if oil or grease in deep groove ball bearing indoor storing up more, easily when they are in deep groove ball bearing rotating along the axis into deep groove ball bearings inside. Deep groove ball bearing chamber is best not to apply oil or grease, if must apply to control shall not have storing up in deep groove ball bearing interior. 4, paint, rust prevention: paint rust is characterized by multiple in sealing type motor, the motor sound is very good, when it is assembled but put some time in the warehouse, the motor sound is very big, remove the deep groove ball bearings with serious rust phenomenon. Before a lot of manufacturers will think is a problem of deep groove ball bearings, through our continuous publicity, motor factory now have realized mainly is a question of insulating varnish. Acid varnish comes out of the problem is mainly due to the formation of corrosive substances under certain temperature, humidity, the deep groove ball bearing channel after corrosion lead to damage of deep groove ball bearings. The problem now is only to choose good insulating paint, after drying and ventilation assembly after a period of time. Deep groove ball bearing's life is closely related to manufacturing, assembly, use, and must be made at each link to make the deep groove ball bearing is in optimum operation state, so as to prolong the service life of deep groove ball bearings. Correct use of deep groove ball bearing for jiaxing bearing running better, more is to introduce the jiaxing bearing group of deep groove ball bearings use the matters needing attention, more advisory welcome call jiaxing bearing group sales co. , LTD.
