The negative pressure generated in the IKO bearing can cause water to intrude from the main seal, and the structure of the hole seal has a large influence on the negative pressure. Therefore, lower IKO
The negative pressure in the bearing is a basic requirement to prevent water from entering. The most effective method is to make the hole seal not directly in contact with water, while retaining the original function of the hole seal - preventing water and dirt from invading from the side of the roll neck. The sealing method uses surface contact instead of line contact. Whether it is running or stationary, the surface contact hole seal has good sealing performance. Therefore, the new ultra-capacity sealed cleaning roller neck IKO bearing has higher reliability than the conventional sealing roller neck IKO bearing.
In addition, IKO Bearings Italy Seals has recently developed a new generation of oil and grease seals MudBlock. Its optimized design of the sealing structure can effectively prevent the intrusion of dirt. The conventional sealing structure has a radial sealing lip, a clamping spring between the outer diameter and the race, and a fixed sealing ring. The new structure has a push baffle between the bushing and the seal ring. The outer surface of the seal ring and the inner diameter of the bushing are rubber, and the inner lip is pre-lubricated with waterproof grease. MudBlock can be made from a variety of elastic materials depending on operating conditions and application requirements. These materials include: nitrile, polyacrylate, fluorinated synthetic rubber, and the like.
