>> JM90 - Bronze wrapped bearings
 

++ 구조 및 기능

▶ 기저철판 : (Bronze backing )
뛰어난 항 부식능력을 구비하여 수중 및 약산, 강 알칼리성 장소에서도 사용할수 있다.
청동 재질은 마찰운동 시 우수한 발열작용으로 냉각기능을 한다.

  ▶ 장 점
  1. 두께가 얇으면서도 고하중에 사용할 수 있어 소형 경량화 설계에 이상적이다.
  2. 낮은 마찰계수 가지며 우수한 열전도율을 지녔다.
  3. 우수한 내화학성를 지니며 내마모성 뛰어나다.
  4. 외부 이물질의 유입으로 부터 상대면을 우수하게 보호한다.
  5. 표준화 생산되어 납기가 빠르다.
  6. 저속의 고하중, 충격하중, 요동운동 및 단속운동에 이상적이다.
  7. Grease 윤활시 고속사용이 가능하다.
