What's the relationship between bearings and seals?

bearings and seals

Bearings and seals, a bearing seal, in particular a ball bearing seal, in which the ball bearing seal extends upwardly on the end face of a circular ring with two rounded projections, said diameter being smaller The inner diameter of the protrusion is matched with the outer diameter of the inner ring of the ball bearing. The larger diameter protrusion matches the outer diameter of the ball ring of the ball bearing; the inner diameter of the sealing ring is not smaller than the inner diameter of the ball bearing. The inner aperture. It has the characteristics of preventing grease from catching fire, avoiding frequent refueling, and having a simple structure. It is widely used in bearings.

bearings and seals
A bearing seal ring is characterized in that two circular protrusions are extended upwards on one end face of a circular ring, and the inner diameter of the smaller diameter protrusion is equal to the outer diameter of the inner ring of the ball bearing. In cooperation, the larger diameter protrusion matches the outer diameter of the ball bearing ball ring; the inner diameter of the seal ring is not less than the inner diameter of the inner ring of the ball bearing.

The difference between the bearing ring and the apron:
Iron seal bearings are used at high speeds and in environments where protection is not high.
Rubber seal bearings are used for low speed, dust, and water, but they cannot be used for oil seals (except for special bearings).
When selecting, it is necessary to know its material, purpose, etc. The correct selection of bearings has a direct connection to future maintenance, eliminating the need for troublesome brains.

bearings and seals
The bearing has a dust cover and a seal, and the two properties are different. ‍
One is dust and the other is a seal. Dust prevention prevents dust from entering the interior of the motor; the seal not only does not allow external dust to enter and the internal grease does not flow easily. Unclean external grease does not easily flow in. The difference between the two in practical applications is not too great. Bearings generally have inner and outer oil covers, which have already played this role and are only required under certain conditions. Dust is indicated by Z, seal is indicated by S, (Felt seal is indicated by FS, and rubber seal is indicated by LS).
