Barden Precision Bearings Super Precision Cylindrical Roller Bearings

Description
Super precision cylindrical roller bearings are designated as Series N10, NN30, N19 and NNU49. NN30 double row bearings are typically used in combination with double direction angular contact thrust bearings in applications where radial stiffness, high radial capacity and high precision support is required. They represent the ideal solution for a floating bearing location, since they are internally adjusting (floating). For axial loads, double direction angular contact thrust bearings, Series 2344 are used in combination with Series NN30 bearings. A single row cylindrical roller bearing (Series N10, N19) would be most commonly used as the “floating” bearing in combination with a set of preloaded angular contact spindle bearings. Double row cylindrical roller bearings have a high load carrying capacity because of the high number of cylindrical rollers in each row, and the exclusive optimized roller crown profile which results in the best load distribution. The cage is of solid machined brass construction, making this bearing suitable for rugged applications. Single row cylindrical roller bearings also have a solid brass cage and are specially designed for the demands of high speed spindles. They are available with both steel and ceramic rollers.
