This deep groove ball bearing carries radial and moderate axial loads on a 65 mm bore, with an outside diameter of 140 mm and a width of 33 mm, weighing 2.13 kg net. It is built as a single row design (H-Series) with a steel sheet metal cage (JN) and seals on both sides (2RSR), giving a limiting speed of 3000 1/min and radial internal clearance CN (Group N). The seals on both sides keep the raceway protected from contamination and retain the internal lubricant, so no external sealing arrangement is required. Radial internal clearance CN suits standard duty applications without unusual thermal or fit-related preload, while the steel cage supports stable ball guidance at the rated speed. Bore type Z indicates the standard bore tolerance for mounting on a cylindrical shaft.
