This single row cylindrical roller bearing carries two ribs on the outer ring and one rib on the inner ring, giving it a semi-locating function that allows axial displacement in one direction while guiding the shaft in the other. Bore diameter is 70.0 mm, outside diameter 125.0 mm, width 31.0 mm, and net mass is 1.69 kg. The E design provides an optimized internal geometry for increased load carrying capacity, and the bearing runs with a machined M1 cage. Limiting speed is 10100.0 1/min, with a reference speed of 3850.0 1/min. Radial internal clearance is CN (Group N), suitable for standard fit conditions without preload requirements. The rib arrangement lets the bearing take up axial loads in one direction while accommodating axial shaft expansion in the other, making it useful where a floating support combined with limited axial guidance is needed. The separable inner and outer rings simplify mounting and dismounting on the shaft and in the housing.
