This single row cylindrical roller bearing has a bore of 50.0 mm, an outside diameter of 90.0 mm, and a width of 20.0 mm, with a net mass of 0.484 kg. The design features two ribs on the outer ring and one rib on the inner ring, making it a semi-locating bearing type NJ. The E design provides an optimized internal geometry for increased load carrying capacity, and the bearing is fitted with a TVP2 cage. Limiting speed is rated at 11100.0 1/min, with a reference speed of 6600.0 1/min. The semi-locating configuration allows the bearing to transmit radial loads while permitting axial displacement in one direction, which is useful where a shaft requires guidance in only one axial direction. Radial internal clearance is in the CN (Group N) range, suitable for standard fit and operating conditions. The polymer TVP2 cage design supports smooth roller guidance at the specified speed ratings, and the overall construction is intended for applications requiring separable inner and outer rings with single row roller loading.
