The reason why the eccentricity is so important is that it directly determines the swivel performance and service life of the universal caster. In other cases of the same size, the greater the eccentricity, the better the swivel performance of the caster, but at the same time, the contradiction is that with the increase of the eccentricity, the moment generated by the load during the use of the caster also increases linearly Large, this will undoubtedly greatly affect the rotation life of the universal wheel.
Conversely, when the other dimensions are the same, the smaller the eccentricity, the safer the caster will bear the load. Therefore, at the beginning of the design of the caster, the eccentricity is considered as life-size. When the eccentricity of a universal wheel is determined, its performance and life are fixed.
In other words, from another perspective, whether the eccentricity of the universal wheel is reasonable can directly explain the good and bad, good and bad of this caster.
