Its main loads are radial loads, while it can also bear certain axial loads from any direction. The manufacturing cost or price is lower. The running resistance is small and the limit speed is high. It can achieve higher running accuracy and quite low vibratory level and can be made into sealed bearing.There are some requirements on installation. The bearing life will be obviously affected when the amount of declination between inner and outer ring axis exceeds 8’~16’. It can be applied to motors, machine tools, vehicles, precision equipments, household appliances, chemical machinery, universal machinery, agricultural machinery etc.
