Development of rolling bearing based on the sliding bearing,china ball bearing its working principle is based on the rolling friction instead of sliding friction, generally consists of two rings, a set of scrolling, and a cage composed of highly versatile, standardization, serialization, high degree of mechanical The basic parts. All kinds of machinery with different working conditions, the rolling bearing load capacity, structure and use of performance are various different requirements. To this end, the rolling bearing wide range of structure. , The basic structure of the inner ring, outer ring, rolling element and cage composed of.
Parts bearing role are:
Radial bearings, the inner ring is usually a tight fit with the shaft,ball bearing manufacturer together with the shaft running, outer ring usually bearing or mechanical shell hole into the transition with the played the supporting role. Some cases, outer ring operation, the inner fixed from the supporting role of inner and oute r rings are running at the same time. Thrust bearings, and shaft tight fit with the movement, said shaft ring, bearing or mechanical shell hole into the transition with the starting and supporting role, said seat. Usually with the help keep the frame uniform arrangement between the two rings for rolling movement within the bearing of the rolling element (ball, roller or needle), shape, size and number of direct impact on the bearing load capacity and performance. Cage In addition to the outside of the uniform can scroll separated, but also from the guide rotation of the rolling element and improve the lubricating properties of the bearing internal role.ball bearing supplier
