This needle roller bearing carries a solid inner ring and locates needle rollers with a machined TV cage, suited for radial load support at a bore diameter of 45.0 mm, outside diameter of 62.0 mm and width of 25.0 mm. Net mass is 215.3 g, limiting speed reaches 9200 1/min while the reference speed is 5100 1/min, and radial internal clearance corresponds to group CN (Group N), the normal clearance range. The solid inner ring design of the NKI series allows direct mounting without a separate inner raceway, keeping radial section low for the given bore. Normal internal clearance suits standard fit conditions, and the TV cage guides the needle rollers evenly around the raceway, supporting stable running at the stated speed limits. As an open bearing without integrated sealing, lubrication and contamination protection must be provided by the surrounding housing arrangement.
