Description
This needle roller bearing carries a solid inner ring and provides a bore diameter of 50.0 mm, outside diameter of 68.0 mm and width of 25.0 mm, with a net mass of 270.03 g. It belongs to the light series and is fitted with a standard cage. The limiting speed is 8400.0 1/min, with a reference speed of 4950.0 1/min, giving a clear margin for continuous operation within the rated thermal conditions. Radial internal clearance is set to CN (Group N), the normal clearance group, suitable for standard shaft and housing fits without additional adjustment. The compact cross-section of the NKI50/25-XL design allows a high load capacity relative to its radial size, making it suitable for applications where radial space is limited but full rated speed and standard clearance are required. Lubrication and sealing are to be provided externally, as no integrated seal is included in this design.
