This is a single row deep groove ball bearing made from corrosion-resistant materials, fitted with seals on both sides and a steel sheet metal cage (JN). Bore diameter is 40.0 mm, outside diameter 68.0 mm, width 15.0 mm, net mass 0.188 kg, and the limiting speed is 5500 1/min. Radial internal clearance is CN (Group N), with bore type Z. The corrosion-resistant construction makes this bearing suitable for applications where standard bearing steel would be prone to rust, while the seals on both sides keep grease in place and protect the internal geometry from contamination. Standard CN clearance combined with the steel sheet metal cage supports smooth running at the rated limiting speed without need for additional relubrication under normal operating conditions.
