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.
Technology:
1. Sealing and Lubrication: The bearing seal uses a top-notch HNBR O-ring for optimal sealing. The exceptional compression and radial seal design enhance the sealing performance. The compensation system and superior grease prevent excessive pressure and greatly improve lubrication reliability.
2. Motor hardfacing: Tungsten carbide particle hardfacing is generously applied on the shirttail and extended to the front of the bit leg to provide extra safeguarding in high-speed, directional, or abrasive conditions.
