This deep groove ball bearing carries radial and moderate axial loads on a 45.0 mm bore, with an outside diameter of 85.0 mm and a width of 19.0 mm. It is a single row design manufactured from corrosion-resistant materials, fitted with seals on both sides and a steel sheet metal cage (JN). The bearing has a net mass of 0.4 kg and a limiting speed of 4550.0 1/min. Radial internal clearance is CN (Group N), which corresponds to standard running clearance for typical mounting and thermal conditions. The seals keep grease inside and contaminants out, so the bearing runs without external relubrication once packed. Its corrosion-resistant construction makes it suitable for damp or otherwise aggressive environments where standard bearing steel would corrode.
