Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in the prior art, the idler bearing assembly is usually sealed by a sealing ring. During use, the idler bearing assembly often leaks oil due to poor sealing effect, thereby causing the idler The life of the roller is greatly reduced; on the other hand, in the prior art, because the dustproof performance of the idler bearing assembly is not good, dust often enters the idler bearing assembly and damages the idler bearing assembly. Increased resistance of the idler due to the complex structure of the bearing assembly

Abstract

A bearing module for the supporting roller is composed of a bearing seat, a bearing in said bearing seat, a sealing part in contact with said bearing and with at least one sealing lip on its internal edge, a cover plate arranged in the front of sealing part and close to the inner surface of sealing seat without gap, and lubricating grease between bearing and sealing part. Its advantages are no leakage of grease and high effect to isolate dust.

Description

Technical field: [0001] The invention relates to idler rollers, in particular to an idler roller bearing assembly. Background technique: [0002] In the prior art, the idler bearing assembly is usually sealed by a sealing ring. During use, the idler bearing assembly often leaks oil due to poor sealing effect, thereby greatly reducing the life of the idler; on the other hand , in the prior art, due to the poor dust-proof performance of the roller bearing assembly, dust often enters the roller bearing assembly and damages the roller bearing assembly. Roll resistance. Invention content: [0003] The technical problem to be solved by the present invention is: in the prior art, the idler bearing assembly is usually sealed by a sealing ring. During use, the idler bearing assembly often leaks oil due to poor sealing effect, thereby causing the idler The life of the roller is greatly reduced; on the other hand, in the prior art, because the dustproof performance of the idler bea...
