What Are the Ways in which Bearing Seals Are Sealed?

The sealing method of rolling bearingcance can be divided into contact sealing and non-contact type. The so-called bearing sits its own seal is to make the bearing itself into a sealing function of the equipment. Such as bearings with dust caps, seals, etc. This seal takes up a lot of space. The so-called bearing plus sealing function equipment, is the equipment end cover and other internal production of a variety of functions of sealing equipment.

1. contact seal has felt ring seal, seal seal seal and so on.

2. non-contact seal has axial crank seal, radial crank seal, oil trench seal, ring seal, etc.

Bearings that live within this life should cause initial fatigue damage (stripping or defecting) on any of their bearing rings or rolling bodies. However, in both laboratory tests and in practical use, it is clear that bearings with the same appearance under the same operating conditions have very different actual life.

In addition, there are several different definitions of bearing "life", one of which is called "working life", which means that the actual life of a bearing can be achieved before damage is usually caused by wear, damage, but by wear, corrosion, seal damage and other reasons.

Bearing seal, a bearing seal, especially a ball bearing seal, ball bearing seal is in a circular ring on one end face extending two round edhes, the diameter of the small raised inner diameter and the ball bearing inner ring outer diameter, the diameter of the larger bump and the ball bearing ball ring outside the diameter match; It has the characteristics of preventing grease from catching fire, avoiding frequent refueling and simple structure. It is widely used in bearings.

A bearing seal, characterized in: on one end surface of the circular ring extends up two circular bumps, the inner diameter of the smaller raised and the inner diameter of the ball bearing is matched, the larger diameter of the bump is compatible with the ball bearing's ball ring outside.
