This single row cylindrical roller bearing carries two ribs on the outer ring and one rib on the inner ring, forming a semi-locating bearing that permits axial displacement between inner and outer rings within the roller path. Bore diameter is 35.0 mm, outside diameter 72.0 mm, width 17.0 mm, net mass 0.295 kg. The E design provides an optimized internal geometry for increased load carrying capacity, running with a TVP2 solid polyamide cage. Limiting speed is 14100 1/min, reference speed 8100 1/min. Radial internal clearance is C4, wider than standard, compensating for interference fits and thermal expansion during operation at elevated temperature differentials. The semi-locating design allows the bearing to take up axial displacement in one direction while transmitting radial loads, making it suitable for shaft arrangements where one bearing position must remain free to move axially. The TVP2 cage guides the roller set at high speed with reduced friction and stable lubricant distribution.
