ball bearings

Ball bearing is a kind of widely applied rolling-element bearing, which is composed of four basic components: ball, inner ring, outer ring and retainer. It uses balls as a carrier to maintain the separation between the inner and outer rings. Ball bearings can reduce rotational friction and support radial and axial loads. Radial ball bearings can withstand moderate radial loads and moderate axial loads. Ball bearings with shields or seals for protection and can be lubricated to last for their working life. Ball bearings are used in most industrial machinery, such as food processing machinery, textile machinery, packaging machinery, printing machinery and machine tools, etc. Generally, ball bearings are made of bearing steel, sometimes made of stainless steel, ceramic or polymer plastic depending on the specific applications. We provide various types of ball bearings in standard specifications, including imperial and metric series. We are also able to customize ball bearings of non-standard dimensions and specifications, non-conventional appearance structures such as slotted, chamfered, flanged ring, and specified materials and accuracy.
