This is a single row deep groove ball bearing made from corrosion-resistant materials, with a bore diameter of 45.0 mm, outside diameter of 75.0 mm, and width of 16.0 mm. Net mass is 0.243 kg, and the limiting speed is 4900 1/min. The bearing is sealed on both sides and fitted with a steel sheet metal cage (JN), giving radial internal clearance in the CN (Group N) range. The corrosion-resistant construction allows use in humid or aggressive environments where standard bearing steel would be prone to rust. The two-side seals retain grease inside the bearing and keep out dirt and moisture, so no external relubrication is needed during service. With CN internal clearance and standard accuracy, this deep groove ball bearing suits general radial and moderate axial loading at the given bore and speed rating.
