NMB bearing RI - ZZ series radial type deep groove ball bearing cage and structure is introduced

NMB bearing RI - ZZ series radial type deep groove ball bearing cage and structure is introduced radial deep groove ball bearings NMB basically consists of outer ring, inner ring, rolling element and cage, seal ( Dustproof set) And spring coil, etc. Decided to NMB radial accuracy of deep groove ball bearing is the key to the ball rolling between the outer and inner ring groove of the roundness, =) and the theory of roundness error 'And' ball sphericity ( =) and the theory of the sphericity error 'And' material 'components. Only completely improve all the above elements of quality requirements, to achieve a higher precision. NMB radial deep groove ball bearing cage: NMB radial deep groove ball bearing outer ring and inner ring, operation channel formed in the outer ring and inner ring relative orbit each other on the surface, a certain number of ball bearing assembly to the operating channels, has a groove cage placed between the inner ring and outer ring, each ball collection in a groove, the groove opening side inside a ball contact area is formed on the surface, at each end bending groove ridge line of the boundary between inner surface and contact surface, the formation of the border curved ridge line parallel to the direction of the ball bearing rotation, basically formed in the groove bottom channel, the channel from the cage around the peripheral extending outward, in a groove on the underside of lubricating oil with the help of the ball rolling through the channel, and lead to peripheral side, has a inclined plane triangle convex edges together to form the outer weeks on the surface of the adjacent grooves between the rake face formed in the direction of the grooves bracket will be relative to the rotation of the caudal, through ball rolling from the above passage into peripheral lubricating oil on the surface of the seat in the convex rake face of the edges, and through the rotation of the cage to the rib after grooves near the leading edge. NMB radial deep groove ball bearing features: radial ball bearings NMB radial deep groove ball bearing is the most representative in the model. In addition to the radial load, but also can withstand axial load in two directions. Radial deep groove ball bearings NMB categories: open, dust cover and seal ring. Has two kinds of metric and imperial. NMB radial deep groove ball bearing cage and carbon steel column roller for single row material F1 race type deep groove raceway used features high-speed ball seal dustproof form 2 z type roller cover gasket double sealed ball bearing material roller bearing steel precision grade.
