Sealed four-row tapered roller bearings

Sealed four-row tapered roller bearings

Sealed four-row tapered roller bearings are newly developed products in recent years and seeing an increasing trend of being applied in metallurgy and other industries. They have obvious advantages in environmental protection, economic saving and releasing labor intensity and other fields.

Structures

There is a O-ring seal mounted on the outer ring of the bearing, which can efficiently prevent fine solid contaminants and water from entering the bearing from the outer shaft and bearing box; On the two sides of the bearing, there mounted a rubber seal with steel bone, which can efficiently prevent fine solid contaminants and water or coolant from entering the bearing, it can also prevent loss of grease from the bearing and attendant contamination of the rolling emulsion.
The specially design rubber seal with steel bone can efficiently utilize the efficient space of the bearings and make the carry capacity of the bearing to a high extent; The garter spring is to be applied on the sealing lip and inner ring of the bearing.
The relative rotation linear speed of the sealing lip and the inner ring can reach 35 m/s, and the fluoro rubber seal lip can be applied under high temperature and it can still keep its fine chemical stability.

Reinforce the seal between the two inner rings of the bearing with steel bone, which can effectively.

Obvious advantages,

--- This type of bearings has totally same size with non-sealed bearings, while their life can increase 20% and 30%;

--- Lubricating grease consumption can be reduced by 80%*90%;
    The bearings with heavy load, particularly rolling mill bearings, are applicable for harsh operating condition or special sealing requirements;

--- Extend bearing maintenance circle;

--- The seals prevent loss of grease from the bearing and attendant contamination of the rolling emulsion

--- Totally substitute non-sealed bearings with same dimensions;

--- Obviously decrease pollution to the environment.
