Abstract

본 발명은 축 방향으로 니이들 베어링을 보지하고, 니이들 베어링이 부드러운 구름을 가질 수 있도록 아웃슬리브의 내측 면과 외측 면사이에 순환형 니이들 베어링 리테이너가 무한 순환하도록 순환 홈을 형성하여 조립 체결하기 위하여, 상기 니이들 베어링 리테이너의 좌우측에 형성된 연결고리가 가이드 레일의 상면에 위치하도록 구성하고, 니이들 베어링을 보지한 순환형 리테이너가 아웃슬리브 양 끝단에서 부드럽게 순환할 수 있도록 반원으로 구성되고, 반원의 내측에는 순환 홈이 형성된 알피스(R-Piece)가 장착되고, 외측에는 앤드 캡(End Cap)이 장착되어, 다각형 구조로 조립된 니이들 베어링 순환형 리테이너가 원활한 순환이 되도록 구성함으로써 내구성 및 저소음, 고정도, 고강성을 유지하면서 무한 직선왕복운동을 부드럽게 이루어지도록 설계 제작된 무한 스트로크용 다각형 니이들 베어링 가이드에 관한 것이다.
