LM29748/LM29710 inch Tapered roller bearings

LM29748/LM29710 inch Tapered roller bearings must be installed in a dry and clean environment. Before installing tapered roller bearings, pay attention to check the matching surface of the shaft and the housing, the end face of the shoulder, the groove and the connecting surface. All mating surfaces must be carefully cleaned and burrs removed. The unfinished surface of the casting must be cleared of residual sand.Before installing the bearing, lubricating oil or kerosene should be used for cleaning, and can be used after the bearing is dry, and to ensure good lubrication. Bearings are usually grease or some lubricating oil. When using grease, high quality grease should be used, such as no impurities, anti-oxidation, anti-rust and extreme pressure. The filling amount of grease is 30%-60% of the volume of bearing and bearing seat, and should not be excessive. Double row tapered roller bearings and pump shaft bearings with sealed structure are filled with grease and can be used directly by the user and cannot be cleaned.
