Product Announcement from RBC Bearings
Journals are designed in a straight (plain) configuration with a flange to accommodate a combination of radial and axial loads with corrosion resistant materials and coatings. Journals are also offered in high temperature and water resistant series.
Typical journal materials are 17-4PH and aluminum. Bearings may also be cadmium or zinc nickel plated as required. In addition, CRES 440C and Inconel® 718 are available upon request. Journal bore and flanged journal face surfaces may also be provided with various liner systems to satisfy specific application requirements.
