Product Description Bearing Steel Nnu 49/750 Chinese Supplier High-Quality Double Row Cylindrical Roller Bearing Cylindrical Roller Bearingsdouble row, with cageAvailable in various designsHigh to very high load ratingsAvailable with cylindrical or tapered boreDouble row cylindrical roller bearings with cage can absorb very high radial forces due to the linear contact between rolling element and bearing ring. They are classified into two general designs which differ in flange position on the inner or outer ring. Double row cylindrical roller bearings can be disassembled and are easily installed or uninstalled. They are suitable for medium to high speeds, but they are rigid and cannot compensate angular misalignments.

The compensation of misaignment or linear expansion of the shaft occurs unrestrained in the bearing so a sliding fit in the housing or on the shaft is not necessary.By default, cylindrical roller bearings by KRW are designed with optimised contact areas between roling elements and raceways. Due to the logarithmic prohling of the cylindrical rollers, damaging edge tension is avoided even with very high loads.Double row cylindrical roller bearings with cage are dismountable and non-latching bearings that are available in the standard designs NNU and NN.The outer ring of NNU bearings has three integral flanges while the inner ring is designed without flanges. For NN bearings, the three integral flanges are located on the inner ring and the outer ring has no flanges.Double row cylindrical roller bearings with cage are suitable for the absorption of very high radial forces and offer especially high rigidity. Cylindrical roller bearings can be delivered with cylindrical or tapered bore.
