Aurora Bearing offers maintenance-free PTFE lined alternatives to fractured race and light series spherical bearings used in hydraulic cylinders in both Metric and Inch dimension series. They are best used in static situations where potential misalignments exist that can not be accommodated by plane bushings or clevises and pins. Maintenance-free PTFE lined bearings have a closer tolerance fit between ball and race which results in greater precision and will provide maximum service life vs. metal on metal fractured race bearings that require maintenance and lubrication.
Fractured race bearing part numbers generally carry a suffix “ES”, and this is true in the Aurora line. Replacing this suffix with an “ET-2RS” will specify the dimensional equivalent with a self lubricating PTFE liner. Beyond the cataloged and stocked bearings, Aurora also can and does manufacture full swage design equivalents for the most demanding dynamic applications.
