This single row cylindrical roller bearing, NJ204-E-XL-TVP2, has a bore diameter of 20.0 mm, an outside diameter of 47.0 mm, and a width of 14.0 mm, with a net mass of 0.113 kg. The design features two ribs on the outer ring and one rib on the inner ring, corresponding to type NJ, which allows axial displacement of the inner ring relative to the outer ring in one direction, making it a semi-locating bearing. The cage is of TVP2 type, and the design follows the E series with optimized internal geometry. The limiting speed is 22000 1/min, with a reference speed of 12800 1/min. The radial internal clearance is CN (Group N), corresponding to standard clearance suitable for typical operating conditions without significant preload or excessive play. The one-directional axial displacement capability allows compensation for thermal expansion of the shaft or minor misalignment during operation. The TVP2 cage, made of glass-fiber-reinforced polyamide, supports smooth roller guidance and is suitable for moderate to high-speed applications within the specified limiting and reference speed ranges. This bearing is intended for radial load support and axial guidance in one direction, based on its semi-locating design.
