Double row cylindrical roller bearings are divided into two ways:
(1) NN0000 double row cylindrical roller bearing This kind of bearing is compact in layout; it is deformed when receiving load. Despise the squatting С С. Because its outer ring has no ribs; therefore, it can separate the outer ring and inner ring of the device. Components (with rollers and cages); do not constrain the axial displacement of the shaft or casing; compare with single-row cylindrical roller bearings of the same radial dimension; accept larger radial loads.
(2) NN0000K type tapered bore double row cylindrical roller bearing This kind of bearing is compact in layout; it is deformed when receiving load. 虼 虼 糜诨 岬 岬 岬 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承 轴承
This type of bearing has no ribs on the outer ring; therefore it can separate the outer ring and inner ring assembly (with roller and cage); does not constrain the axial displacement of the shaft or outer casing; single row cylindrical roller bearing with the same radial dimension More comparative; can accept larger radial loads.
