Rolling bearings support and guide, with minimal friction, rotating or oscillating machine elements – such as shafts, axles or wheels – and transfer loads between machine components. Rolling bearings provide high precision and low friction and therefore enable high rotational speeds while reducing noise, heat, energy consumption and wear. They are cost-effective and exchangeable machine elements that typically follow national or international dimension standards.

볼 및 롤러 베어링

두 가지 기본 유형의 롤링 요소는 두 가지 기본 유형의 롤링 베어링을 구분합니다:

볼 → 볼 베어링
롤러 → 롤러 베어링

볼과 롤러는 레이스웨이와 접촉하는 방식이 다릅니다.

Balls

볼은 링 레이스웨이와 점 접촉합니다. 베어링에 작용하는 하중이 증가함에 따라 접촉점은 타원형 영역이 됩니다. 접촉 면적이 작아지면 구름 마찰이 적어 볼 베어링이 고속을 수용할 수 있지만 하중 전달 능력도 제한됩니다.

롤러

롤러는 링 레이스웨이에 선으로 접촉합니다. 베어링에 작용하는 하중이 증가하면 접촉 라인의 모양이 다소 직사각형이 됩니다. 롤러 베어링은 접촉 면적이 넓고 결과적으로 마찰이 더 크기 때문에 같은 크기의 볼 베어링보다 더 무거운 하중을 견딜 수 있지만 속도는 더 낮습니다.
