What Are the Bearing Seals?

The sealing method of rolling bearings can be divided into contact seals and non-contact. The so-called bearing comes with sealing is the bearing itself made into a sealing function equipment. Such as bearing with dust cover, seals, etc. This seal takes up space very much. The so-called bearing plus sealing function equipment, is the equipment end cover and other internal production into a sealing equipment with a variety of functions.

1. contact seal has felt ring seal, seal ring seal, etc.

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

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

There are also several different definitions of bearing "life", one of which is called "working life", which means that the actual life of a bearing before damage is caused by wear, damage is usually not caused by fatigue, but by wear, corrosion, seal damage, etc.

Bearing seal seamounts, a bearing seal, especially a ball bearing seal ring, the ball bearing seal ring is in a ring-shaped end surface extended up two round bumps, the diameter of the smaller raised inner diameter and the outer diameter of the ball bearing, the larger diameter of the bulge with the ball bearing's ball bearing outer diameter; 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 ring, characterized by: two circular bulges extended upward on one end surface of the ring, the inner diameter of the smaller bulge is compatible with the outer diameter of the inner ring of the ball bearing, the larger bulge of the bearing is matched with the outer diameter of the ball bearing; the inner aperture of the seal ring is not less than the inner diameter of the inner circle of the ball.
