Disc Bearing with Rubber Cushioned Outer Ring
Used on Krause with 1-3/4" Axles
CDS series bearing assemblies consist of a heavy duty NTN BCA® disc bearing and a special configuration separable rubber housing. These assemblies are designed for use in two-piece cast housings which when bolted together at mounting capture the bearing assembly in the appropriate position between each half. The extension on the rubber housing with the thru hole is intended to match up with a relubrication hole in one of the casting halves. Knurled surfaces on the O.D. of the outer ring are gripped by the rubber, which is compressed at mounting, to prevent outer ring movement thus assuring the relube hole in the outer ring stays in alignment with the rubber housing grease hole. This permits relubrication of the bearing through a grease fitting installed in the cast housing.
