Of the bearing seal according to the structure of the form itself to differentiate, can be divided into contact sealing effect, but also for contact and can be divided into radial sealing load axial sealing effect is the same, according to the structure of the sealing ring is divided into single lip seal effect, but also can appear the effect, in the sealing effect is not the same, and the effect of the reflected also has a certain meaning, so better to reflect the situation, what about more information bearing seal is started by the introduction of technology.
Can support bearing in this respect additional sealing device can effectively prevent the invasion of the foreign body, but in this kind of sealing device will increase the axial size of the form of organization, and from these aspects to bearing using the effect of charge inconvenient installation and maintenance, and the sealing performance can also be journal Dutch shell suitable parts of the processing precision and the effect of position tolerances.And the bearing with seal can not only have a good sealing lubrication environment effect, and can solve the problem of the support part, but also can save the effect of complex lubrication system, so in the compact structure, seal requirements of the strict part, are recommended to use the sealing effect.
Bearing the meaning of performance in this aspect is also reflected from the structure of sealing effect, at the same time in other ways also can better to reflect the effect, in the same way, can better reflect the effect of sense changed this change effect, this is the case in the sense of a kind of expression.
