Carries radial loads with a solid inner ring, giving the needle roller bearing a bore diameter of 42.0 mm, outside diameter of 57.0 mm and width of 30.0 mm at a net mass of 222.51 g. The light series design keeps the cross-section compact while maintaining a limiting speed of 9800 1/min and a reference speed of 5400 1/min. The radial internal clearance is set to C3 (Group 3), providing extra internal play to compensate for interference fits and thermal expansion during operation. Fitted with a standard cage, the NKI42/30-XL-C3 suits mounting positions where a solid inner ring is required and where the C3 clearance class supports stable running under load.
