This deep groove ball bearing carries radial and moderate axial loads on a shaft of 30.0 mm bore diameter, with a 72.0 mm outside diameter and 19.0 mm width. It is a single row design made from corrosion-resistant materials, fitted with seals on both sides, and uses a steel sheet metal cage (JN). Net mass is 0.354 kg, and the limiting speed is 6000.0 1/min. The corrosion-resistant construction allows use in environments where moisture or contamination would otherwise attack standard bearing steel, while the seals on both sides keep grease inside and prevent ingress of dirt and moisture, reducing maintenance needs. The radial internal clearance falls in group CN, suitable for standard operating conditions without excessive preload or looseness. The steel sheet metal cage provides guidance for the balls while keeping the design lightweight, and the bore type Z should be checked against shaft fit requirements before mounting.
