The present invention relates to a floating seal for a track roller in which a rotation sealing and a fixing sealing are closely attached to each other to form a pair, and a manufacturing method thereof, wherein a support unit with an abrasion resistant surface is made of an expensive abrasion resistant material, a body portion is made of a cheap general material to be manufactured in a centrifugal casting method, and the support unit and a body are assembled to bond the support unit and the body in a blazing method to manufacture the rotation sealing and the fixing sealing, thereby reducing manufacturing cost while maintaining wear resistant as it is, and improving productivity.

    본 발명은 회전씰링과 고정씰링이 서로 밀착하여 한 쌍을 이루는 트랙롤러용 플로팅 씰에 대한 것으로, 내마모면이 있는 지지부는 값비싼 내마모 재질로 제작하고, 몸체부위는 값싼 일반재질로 하여 원심주조로 제조한 다음, 지지부와 몸체를 조립하여 이들을 블레이징 공법으로 접합하여 회전씰링과 고정씰링을 제조함으로써, 내마모성은 그대로 유지하면서 제조단가를 낮추고, 생산성을 향상시킬 수 있는 트랙롤러용 플로팅 씰 및 그 제조방법에 관한 것이다.
