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 is applied many applications recommend a small amount of end play in the final adjustment because preload is hard to measure without equipment specifically designed for that purpose and that equipment is not normally available in the field again it is most important that the oem s instructions are followed with regard to bearing adjustment and maintenance effect of preload or clearance on life and failure mode 4
