Description
This needle roller bearing carries a solid inner ring and a full complement of needle rollers guided in a cage, giving it a bore diameter of 75.0 mm, outside diameter of 105.0 mm and width of 25.0 mm, with a net mass of 0.639 kg. It belongs to the NKI light series and reaches a limiting speed of 5400 1/min, with a reference speed of 3300 1/min. The radial internal clearance falls in group CN, and the standard cage keeps the rollers evenly spaced, supporting smooth rotation at the rated speeds. Thanks to its light-series design, the bearing offers a compact radial cross-section relative to its load-carrying capacity, making it suitable wherever a slim radial envelope combined with high radial load capacity at the stated bore and outside diameter is required.
