| LR**4NPPU/KDDUTrack Roller Bearing-Rings and roller bearing steel by Material Science Gcr*5, the vacuum quenching tempering treatment, an outer ring of the bearing internal use of internal structure design and thickening of double row angular contact ball bearing, the bearing has higher load carrying capacity. 1 small resistance, long service life, wide application with R**0 arc supporting rollers at work, between wheel and rail by Li Junyun, avoid stress concentration, small frictional resistance, so that the service life of the product is improved a lot. Most double support rollers can also through the inner ring on the grease lubrication holes to repeat, in order to adapt to the harsh working environment. 2 simple and convenient installation Roller bearing configuration of eccentric shaft and shaft, the installation is convenient, the eccentricity of eccentric wheel can be adjusted by the proper preload. 3 stable running, small error -LR series roller support in addition to outside rolling bearing standard production, all bearing company adopts the special processing technology, for the inner ring is fixed, the outer ring special working mode rotation. Product features: the arc surface processing of excircle is a R**0 (suffix U), so that in the process of using force good products. | |
