Single-row cylindrical roller bearing carrying radial loads through line contact between rollers and raceways, with two ribs on the outer ring and one rib on the inner ring, forming a semi-locating configuration that permits axial displacement in one direction while providing guidance in the other. Bore diameter is 100.0 mm, outside diameter 215.0 mm, width 73.0 mm, net mass 11.96 kg. The bearing uses a polyamide cage (TVP2) and the reinforced E design for increased roller complement and load rating. Limiting speed is 4250 1/min, reference speed 2500 1/min. Radial internal clearance corresponds to CN (Group N), the normal clearance range suited for standard fits and typical operating temperatures. The roller and rib geometry allows the inner ring to move axially relative to the outer ring, accommodating shaft expansion while the fixed side of the shaft arrangement provides axial location elsewhere. The polyamide cage supports smooth roller guidance at the given speed range, and the open, non-sealed design requires external lubrication and sealing arrangements appropriate to the application environment.
