Provides combined sealing protection for the shaft-housing interface in an SNS-type bearing housing arrangement, using a taconite-type seal design with an outside diameter of 282.5 mm and a width of 69.0 mm. Net mass is 7.2 kg, reflecting the solid construction typical of this sealing ring category. The combined sealing arrangement offers protection against both solid contamination and moisture ingress, making it suitable where the shaft operates under exposure to dust, dirt, or water in the vicinity of the bearing housing. This sealing ring is matched dimensionally to the SNS-housing series and should be installed accordingly to maintain the intended sealing performance at the specified outside diameter and width.
