installation and maintenance tapered roller bearings should always be installed and maintained according to the original equipment manufacturer s recommendations failure to lubricate install adjust and maintain these bearings properly can result in shortened bearing life equipment failure and personal injury tyson tapered roller bearings come from the factory with a light coat of preservative designed to keep the bearings from rusting it does not provide adequate operating lubrication the bearings must either be thoroughly greased or immersed in the oil used in oil bath lubrication before assembly the bearings and lubricant must be kept very clean through the installation process it is not necessary to remove the preservative coating before installation as long as the bearing is clean adjustment of the bearings is critical to achieving the best possible bearing life as shown in the graph a slight amount of preload provides maximum life but it falls off dramatically if too much preload

rbc tapered thrust bearings the primary application for these bearings is in the heavy truck and trailer industry applications include steer axles for trucks tractors and construction equipment and landing gear for class 8 trailers due to the tapered roller design these bearings offer significant thrust load capacity and can be used in a variety of other applications where that is a requirement both the races and rollers of the thrust bearings are case hardened which offers advantages in applications where shock loads and/or misalignment are present rbc utilizes a full complement of rollers where possible which provides higher load capacity than designs using roller retainers also there is better roller alignment with the full complement design this improves the life of the bearing as an option rbc offers many sizes of thrust bearings with an integral seal these bearings are designated with a -s suffix this provides ease of installation and simplifies the design of the end product bear
