Description
This needle roller bearing carries a machined outer ring without a flange, with the radial section built for maximum needle roller capacity within a light series outside diameter of 62.0 mm. The TV cage guides the needle roller complement, keeping mass at 145.0 g. Limiting speed is rated at 9200.0 1/min, with a reference speed of 5400.0 1/min under standard load and lubrication conditions. The light series design gives a reduced cross section compared to heavier NK series bearings, suiting installations where radial space is limited but a solid outer ring is still required. As the bearing has no inner ring, it must run on a hardened and ground shaft seat, and the TV cage keeps the needle rollers correctly spaced and aligned during rotation. Speed and mass figures indicate a lubrication regime consistent with the stated reference and limiting speed values, allowing operation with grease or oil depending on the application requirements.
