Four Row Cylindrical Roller Bearings

In terms of performance, the advantages of double-row full complement cylindrical roller bearings are concentrated in "heavy load bearing" and "impact resistance". First, **Extreme radial load carrying capacity**: The double-row full complement design makes the radial dynamic load rating 50%-70% higher than double-row cylindrical roller bearings with cages, 3-4 times higher than deep groove ball bearings of the same size, and can withstand radial loads of thousands of kN , easily cope with the extreme heavy loads of rolling metal in rolling mills and crushing ores in crushers; secondly, **excellent impact resistance**: double-row rollers evenly share the impact load, and the stress strength of a single roller is greatly reduced. In working conditions with frequent starts and stops and load fluctuations (such as When the crane hook lifts heavy objects), it can effectively absorb impact energy and avoid instantaneous overload damage to the bearings; thirdly, ** strong structural rigidity…
