This needle roller bearing carries a solid inner ring, giving it a full complement of rolling elements guided within a standard cage for radial load support in a compact cross-section. Bore diameter is 42.0 mm, outside diameter 57.0 mm, and width 30.0 mm, with a net mass of 222.51 g. The limiting speed reaches 9800 1/min, with a reference speed of 5400 1/min, corresponding to the light NKI series design. Radial internal clearance falls within the CN (Group N) range, suitable for standard fit conditions without preloading requirements. The solid inner ring allows precise radial guidance of the shaft, making this bearing suitable for applications where a defined, low-clearance radial fit is needed within the stated speed limits. The standard cage design maintains roller spacing and supports smooth operation across the specified speed range.
