This single-row cylindrical roller bearing has an inner diameter of 15.0 mm, outer diameter of 35.0 mm, and width of 11.0 mm, with a net mass of 0.048 kg. The outer ring has two ribs and the inner ring has one rib, forming a semi-locating design that allows axial displacement in one direction while providing guidance in the other. The E design indicates an optimized internal geometry for increased load rating, and the bearing uses a TVP2 cage. Limiting speed is rated at 31000 1/min, with a reference speed of 17900 1/min. Radial internal clearance corresponds to the CN (Group N) normal range, suitable for standard fit and operating conditions without preload requirements. The semi-locating arrangement permits the bearing to accommodate axial shaft movement caused by thermal expansion while still transmitting radial loads, making it suitable for shaft positions where one bearing must remain axially free. The polymer TVP2 cage supports smooth roller guidance at the given speed range, and the separable inner ring construction simplifies mounting and dismounting during assembly.
