High Quality Ball Bearings Manufacturer

Ball bearings are a part of rolling bearings. As a professional bearing supplier and one of the local China bearing brands, ZWA ,one of national ball bearing company, has its own ball bearing factory and the business covers home and abroad. Compared with roller bearings, ball bearings are point contact which makes the obstruction is small, and the contact section is oval. Ball bearings are composed of an inner ring, outer ring, cage or retainer, and balls. The balls are mounted between the inner ring and outer ring. This kind of bearings allows for smooth, high-speed motion, reduced friction, and both axial radial load capacity. The main function of ball bearings is to confirm the relative position of two parts usually shaft and housing, make them rotate freely, and transmit the loads in between. Especially in those high rotating speed conditions, the function can be expanded to free rotating without abrasion.



Deep groove ball bearings are the typical rolling bearings which have the most widely application. It’s suitable for those working conditions with higher rotating speed, lower noise and vibrating levels. Meanwhile, this kind of bearings is easy to mount or dismount, require for less maintenance and inspection.



ZWA’s deep groove ball bearings include single row and double row ones. For the single row deep groove ball bearings which are also the most widely used type, ZWA offer it with both capped and open. For the capped ones, it includes anti-rust design and anti-oil design. For the anti-dust design, the bearings are with pressed steel cap. And for the anti-oil design, the bearings are with seals to prevent lubrication leaking from inside.For the double row deep groove ball bearings, while there is deviation of alignment between the inner ring and outer ring, extra load will occur which will cause extra loads to the balls and cages. In this case, the service life of the bearing will reduced. Therefore, the max allowable deviation is only 2 arc minute. Any bigger deviation will increase the noise level.



In the past years, ZWA has offered hundreds pieces of deep groove ball bearings, especially single-row ones to the customers. With higher precision and excellent performance of the bearings, ZWA has favored the customers to reduce the cost, increase the productivity and prolong the service life of the equipment.
