HR Series Rubber Sealed Bearing Bits
Journal bearing.Hardfaced head bearing surface.inner hole of cone is silver-plated.The load capacity and seizure resistance of the bearing is greatly improved.0 ring seal is made of the more wear resistance high saturated buna-N with the increased seal section and precisely designed sealing flflange in the cone sealing area increased the reliability of the seal.
