This cylindrical roller bearing carries the single row of rollers guided by a polyamide cage (TVP2) between 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 the removable inner or outer ring simplifies mounting. Bore diameter is 50.0 mm, outside diameter 110.0 mm, width 40.0 mm, and net mass is 1.75 kg. The reinforced E design increases load capacity within the same envelope. Limiting speed reaches 8900 1/min, with a reference speed of 4900 1/min. Radial internal clearance is C3, wider than standard, compensating for interference fits and thermal expansion during operation. The semi-locating configuration allows the bearing to accommodate shaft thermal growth axially while still providing radial guidance, making it suitable where one bearing position must remain fixed and the other free to float. The polyamide cage (TVP2) supports smooth roller guidance at the given speed range, and the design is intended for grease or oil lubrication as applicable to the mounting arrangement.
