Precision Cylindrical Roller Bearing - Double Row with Tapered Bore. Precision Double-Row Cylindrical Roller Bearings utilize a modified cylindrical roller that provides line contact with the inner and outer ring raceways. They are suitable for high speeds and have a high radial load capacity. The rollers are guided by ribs on the inner ring. These bearings are not be able to accept any axial loading, however they will allow some axial movement. The inner and outer rings are separable which may aid in the assembly/disassembly of components. The ‘NN’ Type bearings have three shoulders on the inner ring that retains the rollers and cage. The outer ring has no shoulders. They have a tapered bore and machined brass cage. Radial clearance of tapered-bore bearings can be adjusted during the mounting process. These bearings have high radial rigidity and are used primarily for high-speed, high-accuracy applications such as; main spindle support for lathes, milling machines and machining centers.
