The DZA series has a segmented outer ring and an integrated inner ring design, with a cage and fully loaded roller bearings. Suitable for parts that require high inner ring rotation accuracy.With large diameter bearings.The bearings work is very strict in certain areas.DZE also provides joint bearing and large diameter bearings.DZE is a ball and roller bearing company.
Performance: Flexible rotation and high stiffness, significantly reducing material costs. Install two sets of large diameter bearings raceways and rollers at a right angle cross together, with adjacent rollers facing in opposite directions. Isolation blocks are installed between rollers, and support washers are also installed on the rollers, which allows the two half columns of rollers to be accommodated in the same space. The angle and conical geometry of the bearing ke prakar make the effective span of the bearing several times larger than the actual width of the bearing itself.
Load: Ca=234000N basic rated dynamic load, axial C0a=690000N basic rated static load, axial Cr=166000N basic rated dynamic load, radial C0r=340000N basic rated static load,
